    BEFORE:        DAUGHTREY, ROGERS, and COOK, Circuit Judges.
    ROGERS, Circuit Judge. This state-law product liability case arose from birth defects in
    the form of serious physical and cognitive disabilities suffered by plaintiff Rheinfrank’s child.
    The defects were allegedly caused by the antiepileptic drug Depakote, manufactured by
    defendant Abbott Laboratories, and taken by Rheinfrank while pregnant with the child.
    Rheinfrank contended that the labeling on the drug was not adequate. The district court held that
    Rheinfrank’s Ohio law failure-to-warn claim—to the extent that it was based on Abbott’s failure
    to warn of the risk of developmental delays—was preempted by federal drug labeling law
    because the Food and Drug Administration had rejected label changes containing such warnings
    even well after Rheinfrank’s pregnancy. A jury found for Abbott on several remaining claims,
    and Rheinfrank appeals the overall judgment for defendant. Each of Rheinfrank’s contentions on
    appeal is not sufficient to warrant reversal. The district court’s preemption analysis was correct.
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    With respect to the jury verdict, the district court did not abuse its discretion in putting limits on
    expert testimony related to the scope of the experts’ respective expertise, or by rejecting
    requested jury instructions that were repetitive, confusing, or both.
    I.
    For nearly her entire life Rheinfrank has suffered from epilepsy. In 1988, after a relapse
    of her epileptic seizures, she began taking two antiepileptic drugs, one of them Depakote. She
    continued that course of treatment over the next fifteen years, including the years she was
    pregnant with each of her first four children. Late in 2003, while she was still on her daily
    regimen of the two drugs, Rheinfrank became pregnant with her fifth child, M.B.D. While she
    was carrying M.B.D. she continued to take both antiepileptic drugs daily.              In July 2004
    Rheinfrank gave birth to M.B.D., who was later diagnosed with physical deformities and
    cognitive disabilities, including Fetal Valproate Syndrome. Those disabilities Rheinfrank now
    blames on her daily use of Depakote.
    The Food and Drug Administration (FDA) first approved Depakote in early 1983, and, by
    the time Rheinfrank was first prescribed the drug in 1988, it had also been designated a
    Pregnancy Category D drug by the FDA. As of 2003, the drug’s label accordingly included a
    “Black Box Warning” cautioning about the risks the drug posed to developing fetuses:
    TERATOGENICITY:
    VALPROATE CAN PRODUCE TERATOGENIC EFFECTS SUCH AS
    NEURAL TUBE DEFECTS (E.G., SPINA BIFIDA). ACCORDINGLY, THE
    USE OF DEPAKOTE TABLETS IN WOMEN OF CHILDBEARING
    POTENTIAL REQUIRES THAT THE BENEFITS OF ITS USE BE WEIGHED
    AGAINST THE RISK OF INJURY TO THE FETUS. THIS IS ESPECIALLY
    IMPORTANT WHEN THE TREATMENT OF A SPONTANEOUSLY
    REVERSIBLE CONDITION NOT ORDINARILY ASSOCIATED WITH
    PERMANENT INJURY OR RISK OF DEATH (E.G., MIGRAINE) IS
    CONTEMPLATED. SEE WARNINGS, INFORMATION FOR PATIENTS. AN
    INFORMATION SHEET DESCRIBING THE TERATOGENIC POTENTIAL
    OF VALPROATE IS AVAILABLE FOR PATIENTS.

    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    The “Usage and Pregnancy” section of the same label further underlined these risks:
    Usage in Pregnancy
    ACCORDING TO PUBLISHED AND UNPUBLISHED REPORTS,
    VALPROIC ACID MAY PRODUCE TERATOGENIC EFFECTS IN THE
    OFFSPRING OF HUMAN FEMALES RECEIVING THE DRUG DURING
    PREGNANCY. THERE ARE MULTIPLE REPORTS IN THE CLINICAL
    LITERATURE WHICH INDICATE THAT THE USE OF ANTIEPILEPTIC
    DRUGS DURING PREGNANCY RESULTS IN AN INCREASED INCIDENCE
    OF BIRTH DEFECTS IN THE OFFSPRING. ALTHOUGH DATA ARE MORE
    EXTENSIVE        WITH    RESPECT     TO    TRIMETHADIONE,
    PARAMETHADIONE, PHENYTOIN, AND PHENOBARBITAL, REPORTS
    INDICATE A POSSIBLE SIMILAR ASSOCIATION WITH THE USE OF
    OTHER ANTIEPILEPTIC DRUGS. THEREFORE, ANTIEPILEPSY DRUGS
    SHOULD BE ADMINISTERED TO WOMEN OF CHILDBEARING
    POTENTIAL ONLY IF THEY ARE CLEARLY SHOWN TO BE ESSENTIAL
    IN THE MANAGEMENT OF THEIR SEIZURES.
    THE INCIDENCE OF NEURAL TUBE DEFECTS IN THE FETUS MAY BE
    INCREASED IN MOTHERS RECEIVING VALPROATE DURING THE
    FIRST TRIMESTER OF PREGNANCY. THE CENTERS FOR DISEASE
    CONTROL (CDC) HAS ESTIMATED THE RISK OF VALPROIC ACID
    EXPOSED WOMEN HAVING CHILDREN WITH SPINA BIFIDA TO BE
    APPROXIMATELY 1 TO 2%. OTHER CONGENITAL ANOMALIES (E.G.,
    CRANIOFACIAL DEFECTS, CARDIOVASCULAR MALFORMATIONS
    AND ANOMALIES INVOLVING VARIOUS BODY SYSTEMS),
    COMPATIBLE AND INCOMPATIBLE WITH LIFE, HAVE BEEN
    REPORTED. SUFFICIENT DATA TO DETERMINE THE INCIDENCE OF
    THESE CONGENITAL ANOMALIES IS NOT AVAILABLE. THE HIGHER
    INCIDENCE OF CONGENITAL ANOMALIES IN ANTIEPILEPTIC DRUG-
    TREATED WOMEN WITH SEIZURE DISORDERS CANNOT BE
    REGARDED AS A CAUSE AND EFFECT RELATIONSHIP. THERE ARE
    INTRINSIC METHODOLOGIC PROBLEMS IN OBTAINING ADEQUATE
    DATA ON DRUG TERATOGENICITY IN HUMANS; GENETIC FACTORS
    OR THE EPILEPTIC CONDITION ITSELF, MAY BE MORE IMPORTANT
    THAN DRUG THERAPY IN CONTRIBUTING TO CONGENITAL
    ANOMALIES.
    Both before and during her pregnancy with M.B.D. in 2003 and 2004, Rheinfrank had received
    her prescription for Depakote from Dr. Dagmar Lemus, then a resident of internal medicine at
    Cincinnati’s Good Samaritan Hospital. Although Lemus claimed that she did not remember
    -3-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    prescribing Depakote to Rheinfrank, she nevertheless insisted that she would have relayed the
    information on the Black Box warning before prescribing the drug. Lemus further explained that
    she would never have relied on any promotional or other materials when deciding to prescribe
    the drug to Rheinfrank.
    In April 2005, Abbott Laboratories1 sent a letter to Dr. Russell Katz of the FDA to
    propose an update to the already-approved label for Depakote. Abbott had learned of some of
    the early results of a study then being led by Dr. Kimford Meador, investigating the
    neurodevelopmental effects of antiepileptic drugs like Depakote on young children (the “NEAD
    study”). That study uncovered preliminary evidence of “possible developmental delay in some
    children exposed to [Depakote] in utero.” In response to these reports Abbott put together a
    Prior Approval Supplement (“PAS”) that proposed changing Depakote’s label to “provid[e]
    revised information related to teratogenicity and additional information for developmental delay
    and include revisions to the WARNINGS—Usage in Pregnancy and the Patient Information
    Leaflet sections.” Accompanying that supplement were two additional changes: “[a]n outline of
    safety-related changes for teratogenicity/developmental delay and DDI with topiramate” and
    “[n]ew information concerning the use of valproate in women of childbearing potential:
    teratogenicity and developmental delay.”
    Also among the revisions Abbott proposed for Depakote’s label was the inclusion of new
    language under its “Usage in Pregnancy” section, reading in relevant part:
    THERE ARE DATA THAT SUGGEST AN INCREASED INCIDENCE OF
    CONGENITAL MALFORMATIONS ASSOCIATED WITH THE USE OF
    VALPROIC ACID DURING PREGNANCY WHEN COMPARED WITH SOME
    OTHER ANTIEPILEPTIC DRUGS. THEREFORE, VALPROIC ACID SHOULD
    BE CONSIDERED FOR WOMEN OF CHILDBEARING POTENTIAL ONLY

    Abbott Laboratories separately incorporated its pharmaceutical business as “AbbVie” in 2013. Both are named
    defendants, and for convenience we refer to them as “Abbott Laboratories” or “Abbott” in this opinion.

    AFTER THE RISKS HAVE BEEN THOROUGHLY DISCUSSED WITH THE
    PATIENT AND WEIGHED AGAINST THE POTENTIAL BENEFITS OF
    TREATMENT.
    ...
    THERE HAVE BEEN REPORTS OF DEVELOPMENTAL DELAY IN THE
    OFFSPRING OF WOMEN WHO HAVE RECEIVED VALPROIC ACID DURING
    PREGNANCY.
    Abbott further proposed new language under the “Information for Women Who Could Become
    Pregnant” section of its Patient Information Leaflet:
    These medications have also been associated with other birth defects such as
    defects of the heart, the bones, and other parts of the body. Information suggests
    that birth defects may be more likely to occur with these medications than some
    other drugs that treat your medical condition. In addition, there have been reports
    of developmental delay in children born to women taking these medications.
    In support of these modifications Abbott attached to its PAS a “White Paper” discussing some of
    the scientific literature relating to developmental delay in children exposed in utero to
    antiepileptic drugs, including some of the results of the NEAD study.          In February 2006,
    however, the FDA responded to Abbott’s PAS by email, notifying Abbott that the proposed
    sentence discussing developmental delay should not be added to Depakote’s labeling:
    The sentence “There have been reports of developmental delay in the offspring of
    women who have received valproic acid during pregnancy” is based on two recent
    publications (Gaily E et al. Neurology 62(1):28-32, 2004 and Vinten J et al.
    Neurology 64(6): 949-54, 2005) that attempted to correlate children’s
    performance on IQ assessments with maternal prenatal use of valproate but which
    did not adequately control for maternal IQ and maternal educational attainment.
    Maternal IQ and maternal educational attainment are known to strongly correlate
    with children’s performance on IQ assessments and thus would confound any
    attempt to draw a correlation to maternal prenatal valproate use. Given the
    studies’ inability to establish this correlation, the proposed sentence should not be
    incorporated into labeling. A similar proposed sentence in the Patient Information
    Leaflet was removed in the Approval Letter for S-032 (January 11, 2006).
    In May 2007, after Dr. Meador released additional data from the NEAD study, Abbott
    sent another letter to Dr. Katz, this time bearing the subject-line, “General Correspondence –
    Request for Advice regarding Developmental Labeling.” The letter’s purpose was to give the
    -5-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    FDA “an updated analysis of the occurrence of developmental delay in the attached white paper,
    which now includes more compelling data from the [NEAD] study.” Attached to that letter was
    also a 2007 white paper discussing a recently published abstract from Dr. Meador’s NEAD
    study, which the letter claimed provided “the first data with adequate control for maternal IQ
    using a standard IQ measure and showed a significant developmental delay in 185 two-year-old
    children exposed to valproic acid during pregnancy.” Pointing to those data, Abbott proposed
    new language to the “WARNINGS – Usage in Pregnancy” section of Depakote’s label: “There
    have been reports of developmental delay in the offspring of women who have received
    valproate during pregnancy.”
    In March 2008, according to an internal contact report prepared by Abbott, the company
    held a teleconference with Dr. Katz and another representative of the FDA Division of
    Neurology Products “to discuss teratogenesis associated with valproic acid treatment.” The
    report indicated that “Dr. Katz stated they cannot approve this labeling change at this time,” as
    the data was “not ‘ripe’ for inclusion in labeling since it [was] based on interim data from Dr. K.
    Meador and the Neurodevelopment Effects of Antiepileptic Drugs (NEAD) Study group.” The
    report went on to state that:
    [the] FDA feels that the sample size with VPA compared to other agents is small,
    some of the data for the 2 year old IQ evaluation was imputed, and there are too
    many confounding factors to believe the data is reliable at this time point in the
    study. Dr. Katz stated that they want to wait until the study is complete at the six-
    year time point. Dr. Embrescia then commented that there have been a number of
    cases of developmental delay reported through our [p]ost-marketing safety
    surveillance program, and asked whether that might not warrant the change in
    labeling. Dr. Katz asked for the number of cases we have, and Jim responded that
    at the time we submitted the proposed labeling change we had 240 reported cases,
    although many of those cases are confounded by other congenital abnormalities
    the patients have or other medications they were on. Dr. Katz indicated he thought
    these cases were probably too confounded to assess and that he believes this is the
    type of event where they want investigation in a formal setting to confirm.

    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    In April 2009, Abbott once again requested advice from the FDA about adding
    developmental delay warnings to the Depakote label. In its letter Abbott noted that since its
    2005 and 2007 requests, Dr. Meador had published further results from the NEAD study in the
    New England Journal of Medicine, and other researchers had begun publishing the results of
    other studies relating to developmental delay in children exposed to Depakote. Abbott therefore
    requested that the FDA “provide advice on the acceptability of these data for use to support an
    amendment to the current label regarding the risk of developmental delay and/or autism/autism
    spectrum disorder with intrauterine exposure to valproate.”
    In September 2009, the FDA Division of Neurology Products held another teleconference
    with Abbott in response to its latest request for advice. According to Abbott’s internal report of
    that meeting, the FDA “had expressed concerns with Dr. Meador’s data” and had “plans to
    conduct an independent review.” Dr. Katz reportedly stated that the FDA’s “statisticians have
    raised concerns with the [NEAD] study and the methodology for the collection of data,” so that
    “before taking regulatory actions with labeling, they needed time to evaluate the data.” Dr. Katz
    accordingly “stated that they were not yet ready to ‘sign off on labeling language’” concerning
    developmental delay. Moreover, in reply to an inquiry by Abbott as to whether the FDA “would
    be open to [Abbott’s] proposal for labeling language in the interim while the [FDA] completes
    its review,” Dr. Katz noted that Abbott “would be within [its] rights to submit a [“changes being
    effected,” or CBE supplement],” but added that the FDA “would not take action until the review
    of the data was complete.” Two months later, Abbott submitted a CBE labeling supplement to
    add developmental delay warnings to Depakote’s label. In October 2011, years after Abbott’s
    initial request, the FDA approved the addition of a warning about developmental delay on the
    Depakote label.

    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    In 2013 Rheinfrank brought this suit in diversity against Abbott, on behalf of herself and
    M.B.D., asserting several Ohio state statutory claims of strict liability based on design defect,
    inadequate warning, and nonconformance with representations, as well as a number of state
    common law claims. Abbott responded with a number of motions, including one for summary
    judgment on Rheinfrank’s failure-to-warn claim with respect to the risks of developmental delay
    and her request for punitive damages under the Ohio Product Liability Act.
    As to the failure-to-warn claim, Abbott contended that because the FDA had twice
    rejected its proposed modifications to Depakote’s label warning of new evidence of development
    delay, there was “clear evidence” under Wyeth v. Levine, 
    555 U.S. 555
     (2009), that the agency
    would not have approved a developmental-delay warning before M.B.D.’s conception and birth
    ten years earlier. The district court accepted Abbott’s argument, reasoning that:
    because there is clear evidence the FDA would not have approved a change to the
    Depakote label adding a developmental delay warning prior to M.B.D.’s injury.
    The Court finds the FDA’s February 2006 decision that developmental delay
    warnings “should not be incorporated into [Depakote] labeling” and the FDA’s
    2008 belief that “the data do not provide sufficient evidence to support
    [Depakote] labeling changes at this time” constitute “clear evidence” that when
    confronted by the issue in 2003, the FDA would have rejected an attempt to add a
    developmental delay warning.
    Although the district court thus determined that Rheinfrank’s particular claim that Abbott had
    failed to warn of the risk of developmental delay was preempted, the court nevertheless denied
    summary judgment on Rheinfrank’s broader failure-to-warn claim because other questions of
    material fact remained.    The court did grant summary judgment for Abbott, however, on
    Rheinfrank’s request for punitive damages, ruling that she was “barred from recovering for
    punitive damages because the FDA has not made a finding of either fraud or misrepresentation.”
    Before trial, the district court also entered an order limiting in various respects the
    testimony of several of Rheinfrank’s experts.        The first of those limitations involved the
    -8-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    testimony of Drs. Michael Privitera (a neurologist), Howard Saal (a geneticist), and C. Ralph
    Buncher (an epidemiologist), restricting all three from giving any opinion as to what warnings or
    information should have been included in Depakote’s label. As to Dr. Privitera, the court
    concluded that:
    Dr. Privitera is not qualified to opine on the regulatory aspects of the case,
    including whether Abbott was required to send a patient package leaflet directly
    to patients or whether Abbott’s submissions to the FDA should have included
    certain materials. Similarly, testimony about what Defendants should have
    included in the label or what materials should have been submitted to the FDA
    falls outside the scope of his expertise, as it falls under the regulatory component
    and is speculative. Thus, Dr. Privitera also may not testify about whether
    Depakote should have been contraindicated for all women of childbearing years.
    On the other hand, testimony in which Dr. Privitera opines on the medical facts
    and science regarding the risks and benefits of Depakote and compares that
    knowledge with what was provided in the text of the labeling is admissible.
    As for Dr. Saal, the court determined that, although he was “well-qualified . . . to testify as to the
    medical facts and science and compare that information and data with the language of the 2003
    Depakote label,” he was “not an expert in FDA regulations,” and thus “lack[ed] the requisite
    expertise to opine as to the regulatory aspects of the case, including what ‘should’ have been in
    the 2003 label and whether the drug ‘should’ have been contraindicated for women of
    childbearing years, as this assumes regulatory knowledge.” The court concluded much the same
    about Dr. Buncher: despite being “qualified to opine on the medical facts and science regarding
    Depakote and compare that data to a Depakote label,” the court found that he lacked “specialized
    knowledge or expertise in the regulatory field, as he has never worked for the FDA, nor is he an
    expert on FDA labeling regulations.” The court concluded that Dr. Buncher “lack[ed] the
    requisite expertise to opine as to the regulatory aspects of the case, including what ‘should’ have
    been in the 2003 Depakote label and whether Depakote ‘should’ have been contraindicated for
    women of childbearing years, as this assumes regulatory knowledge.”

    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    The court also placed several limitations on the testimony of Rheinfrank’s regulatory
    expert, Dr. Suzanne Parisian. As relevant here, the court ruled that, although a medical doctor
    and former “FDA Medical Officer,” Parisian was nevertheless “unqualified to opine that as of
    2003, Depakote was known to be the most teratogenic drug,” as she is “not a teratologist and
    does not have any specialized knowledge or experience in evaluating [antiepileptic drugs].” Her
    opinion testimony was thus limited to “what actions Abbott could have taken and/or was
    required to take with respect to communicating risks to healthcare professionals,” as well to
    “regulatory requirements relating to the development, testing, marketing, and surveillance of
    prescription drugs.”
    Before the case went to the jury on the four remaining causes of action—strict liability
    under Ohio law for failure to warn and failure to conform to representations, and negligent
    failure to warn and negligent design—Rheinfrank requested a number of jury instructions.
    Among those were requests for instructions concerning the manufacturer’s standard of care and
    knowledge (No. 7), federal requirements for drug labeling (No. 8) and for adding safety
    warnings (No. 11), as well as an instruction concerning strict liability for an inadequate post-
    market warning (No. 14). The district court refused to offer the first three of these instructions
    separately (Nos. 7, 8, and 11), “but incorporated aspects of those proposed instructions where
    appropriate.” As the court later explained when denying Rheinfrank’s motion for a new trial:
    As Plaintiffs acknowledged in their Proposal for Supplemental Jury Instructions
    in Response to [Jury] Question #4, the majority of their Requested Jury
    Instruction No. 7 was incorporated into page 30 of the Civil Jury Instructions
    under Claim One: Strict Product Liability – Defect Due to Inadequate Warning.
    The Court rejected Requested Jury Instruction No. 8, because Plaintiffs cited no
    Ohio authority in support of the instruction and because the Court was concerned
    that an instruction on misbranding would confuse the Jury. The Court
    incorporated the first sentence of Plaintiff’s Requested Jury Instruction No. 11
    into the instruction on Compliance with Regulations. The Court rejected the
    remainder of the requested instruction because it found no reason to deviate from
    -10-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    the Ohio pattern instructions and that superfluous instructions would be
    burdensome and confusing to the Jury.
    The court also excluded an instruction Rheinfrank had proposed on post-market warnings
    (No. 14). Rheinfrank had in fact asked for two instructions, Nos. 13 and 14, both dealing with
    her strict liability failure-to-warn claim. As proposed, Instruction No. 13 would have read:
    STRICT LIABILITY – INADEQUATE WARNINGS/INSTRUCTIONS
    M.B.D. claims that Defendants’ drug Depakote was defective due to inadequate
    warnings or instructions, and as a result caused M.B.D.’s harm, injuries, and
    losses.
    You must find for M.B.D. on her claim that Depakote was defective based on
    inadequate warnings or instructions if the greater weight of the evidence
    demonstrates that:
    (A) At the time Depakote left Defendants’ control, Defendants knew or should
    have known, in the exercise of reasonable care as an expert in the field, that
    Depakote posed increased risks of harm to unborn children; and
    (B) Defendants failed to provide the warnings or instructions that a manufacturer
    exercising reasonable care would have provided concerning Depakote’s increased
    risks of harm to unborn children; and
    (C) As a result of Defendants’ failure to provide adequate warnings or
    instructions, Pamela Rheinfrank’s doctor prescribed and Pamela Rheinfrank used
    Depakote, which resulted in M.B.D.’s harm, injuries, and losses.
    Rheinfrank’s proposed Instruction No. 14, on the other hand, would have added:
    STRICT LIABILITY – INADEQUATE POST MARKET
    WARNINGS/INSTRUCTIONS
    M.B.D. claims that Defendants’ drug Depakote was defective due to inadequate
    post-market warnings or instructions, and as a result caused M.B.D.’s harm,
    injuries, and losses.
    You must find for M.B.D. on her claim that Depakote was defective based on
    inadequate warnings or instructions if the greater weight of the evidence
    demonstrates that:
    (A) After Depakote left Defendants’ control, Defendants knew or should have
    known, in the exercise of reasonable care as an expert in the field, that Depakote
    posed increased risks of harm to unborn children; and
    -11-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    (B) Defendants failed to provide the post-market warnings or instructions that a
    manufacturer exercising reasonable care would have provided concerning
    Depakote’s increased risks of harm to unborn children; and
    (C) As a result of Defendants’ failure to provide adequate post-market warnings
    or instructions, Pamela Rheinfrank’s doctor prescribed and Pamela Rheinfrank
    used Depakote, which resulted in M.B.D.’s harm, injuries, and losses.
    The court ultimately decided to exclude the requested Instruction No. 14, citing two reasons.
    First, the court was “concerned that two, separate strict liability instructions back-to-back would
    be confusing and inconsistent with Plaintiffs’ other proposed instructions and interrogatories.”
    As the court explained in rejecting Rheinfrank’s motion for a new trial:
    For example, [Rheinfrank’s] Requested Jury Instruction No. 15 (Presumption
    Based on Inadequate Warnings) did not distinguish warning and instruction from
    post-marketing warning and instruction. [Rheinfrank’s] Proposed Interrogatory
    No. 1 did not distinguish between warning and instruction and post-marketing
    warning or instruction.
    The court reasoned, moreover, that Rheinfrank “did not justify why [she] proposed two separate
    instructions on the strict liability failure to warn claim, as opposed to one merged instruction.”
    On those grounds the court had instead decided to provide a single “Compliance with
    Regulations in its Civil Jury Instruction,” which explained that “a drug manufacturer bears the
    ultimate responsibility for the content of its label at all times. It is charged both with drafting an
    adequate label and with ensuring that its warning remain adequate as long as the drug is on the
    market.” The court further noted that, before the charge conference, it had circulated its
    Annotated Civil Jury Instructions to both Rheinfrank and Abbott—instructions that did not
    include Rheinfrank’s requested instruction No. 14. During the later charge conference with both
    sides’ counsel—a meeting that lasted more than three hours—Rheinfrank raised no objection to
    the court’s exclusion of Instruction No. 14.

    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    After an 11-day trial, the jury began deliberations on the four remaining claims, during
    which they submitted to the court a question (Jury Question No. 4) about the merged inadequate-
    warning instruction:
    Page 30 of the Civil Jury Instructions, under the Claim One, paragraph two,
    sentence one states “a prescription drug is defective due to inadequate warning or
    instruction if at the time the prescription drug left the control of the manufacturer .
    . .”
    Question: What does “left the control of the manufacturer” mean? When its
    approval was granted or when it left the factory?
    According to the district court, as related in its later opinion rejecting Rheinfrank’s motion for a
    new trial:
    When the Court received Jury Question No. 4 and read it to counsel, discussion
    immediately followed about whether “left the control of the manufacturer” is a
    defined phrase in case law or statute. [Rheinfrank’s] counsel proposed that she
    believed the correct answer to be “when it left the factory.” Jury Question No. 4
    then took on a life of its own when counsel submitted briefs to the Court on the
    question. [Rheinfrank] argued that the Jury must be confused about whether
    Depakote may be defective due to inadequate post-marketing warning or
    instruction. They contended that the Court should submit not only their
    Requested Jury Instruction No. 14, but also Nos. 7, 8, and 11, and direct the Jury
    to refer to the Court’s Civil Jury Instruction on Compliance with Regulations.
    [Abbott] disagreed and argued that when something leaves the control of the
    manufacturer is a fact question for the Jury and that additional instructions would
    be improper. The Court agreed with [Abbotts’] interpretation of Jury Question
    No. 4 and instructed the Jury that “left the control of the manufacturer” was an
    issue for them, as Jury, to decide based on their assessment of the evidence and
    instructions that were previously provided.
    After the jury returned a complete verdict for Abbott, Rheinfrank moved for a new trial,
    arguing, among other things, that the court’s rulings limiting the expert testimony of Drs.
    Privitera, Saal, Buncher, and Parisian were in error and had unfairly prejudiced her case, and that
    her case had been further prejudiced by the court’s erroneous exclusion of her four requested
    jury instructions (Nos. 7, 8, 11, and 14). Rheinfrank contended, in addition, that the court’s
    response to Jury Question No. 4 was improper, and urged the court to reconsider its earlier ruling
    -13-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    granting partial summary judgment to Abbott on its federal preemption and punitive damages
    claim.
    The district court, however, stood by its earlier rulings as to the expert testimony, its
    exclusion of the first three jury instructions (Nos. 7, 8, and 11), and its earlier grant of summary
    judgment to Abbott on Rheinfrank’s failure-to-warn claim about the risks of developmental
    delay and her request for punitive damages. As to the requested Instruction No. 14, the court
    concluded that, by failing to object to the exclusion of the proposed instruction during the charge
    conference, Rheinfrank had waived any objection.         Rheinfrank countered that she had not
    waived her right to argue that the requested instruction should be given, because the jury’s
    Question No. 4 had called into doubt a “key instruction” during deliberations that required
    correction, as in Reynolds v. Green, 
    184 F.3d 589
     (6th Cir. 1999). But the court rejected that
    argument and its analogy to Reynolds, reasoning that:
    The language the Jury expressed its confusion over – “left the control of the
    manufacturer” – was in both of [Rheinfrank’s] Requested Instruction Nos. 13 and
    14. Belatedly charging the Jury in the middle of its deliberations with
    [Rheinfrank’s] Requested Jury Instruction No. 14 would not have answered
    [Rheinfrank’s] question. Further, the proposed scenarios by the Jury – “[w]hen its
    approval was granted” or “left the factory” provided insight into the mindset of
    the Jury, demonstrating that they were proposing definitions for the “left the
    control of the manufacturer,” none of which included any prodding into “post-
    market” scenarios. The Court viewed [Rheinfrank’s] argument – a belated
    attempt to bootstrap several additional jury instructions to an answer to Jury
    Question No. 4 – as inappropriate, unhelpful, and likely to cause greater
    confusion.
    The court further noted that, because the instruction the court gave already “covered the
    differences between [Rheinfrank’s] Requested Jury Instructions Nos. 13 and 14 and cured any
    deficiencies,” its instructions “read as a whole” were appropriate. And even if they were not, the
    court concluded, “based on the evidence and the Jury’s total defense verdict, there would have
    been no difference in the outcome of the case.”
    -14-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    The district court accordingly denied Rheinfrank’s motion for a new trial, and she now
    appeals.
    II.
    The first of Rheinfrank’s several claims on appeal is that the district court prejudiced her
    case by erroneously limiting the testimony of several of her expert witnesses, allegedly entitling
    her to a new trial. But because each of those rulings was based on the district court’s reasonable
    assessment as to the limits of those experts’ respective expertise, and all were consistent with the
    rulings of other courts, the district court could reasonably have limited the testimony as it did
    without exceeding the “great latitude” this court must afford such evidentiary rulings, see
    Taulbee v. Wal-Mart Stores, Inc., 5 F. App’x 361, 363 (6th Cir. 2001) (quoting Rye v. Black
    & Decker Mfg. Co., 
    889 F.2d 100
    , 101-02 (6th Cir. 1989)). Those rulings therefore did not
    amount to an abuse of the district court’s discretion, the standard for this court’s review here,
    Decker v. GE Healthcare Inc., 
    770 F.3d 378
    , 391 (6th Cir. 2014).
    Rheinfrank first argues that the district court erroneously limited the testimony of several
    of her medical experts— Drs. Privitera, Saal, and Buncher—to the medical facts about Depakote
    and how they compared to the details contained on its label, because, Rheinfrank claims, those
    experts were also qualified to opine as to the “adequacy” of that label. But as the district court
    explained, the expertise of each of those witnesses—neurology in Privitera’s case, genetics and
    dysmorphology in Saal’s, and epidemiology in Buncher’s—did not extend to regulatory
    questions like the ones Rheinfrank proposed for them to answer: “what ‘should’ have been in the
    2003 Depakote label and whether Depakote ‘should’ have been contraindicated for women of
    childbearing years.” None of them, after all, had ever worked for the FDA—unlike Dr. Parisian,
    who did testify for Rheinfrank on the regulatory aspects of Depakote’s label. None had any
    -15-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    specialized training or expertise in FDA labeling regulations. Under the standard set forth in
    Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
     (1993), and its progeny, the district
    court need only have decided, by a preponderance, that the expert witness was qualified to
    proffer her testimony, see Decker, 770 F.3d at 391. In this case, given that several other courts
    have similarly limited the testimony of medical experts to questions within their specialized
    medical ken, see In re Gadolinium-Based Contrast Agents Prods. Liab. Litig., No. 1:08 GD
    50000, MDL No. 1909, 
    2010 WL 1796334
    , at *19 (N.D. Ohio May 4, 2010); In re Diet Drugs
    (Phentermine, Fenfluramine, Dexfluramine) Prods. Liab. Litig., No. MDL 1203, 
    2000 WL 876900
    , at *11 (E.D. Pa. June 20, 2000), the court could reasonably have found that
    Rheinfrank’s experts were likelier than not unqualified under Daubert to opine on regulatory
    areas in which they had neither specialized training nor professional experience—including
    opinions as to what ‘should’ have appeared on Depakote’s label, subject as that must be to an
    essentially technical, regulatory judgment. The district court consequently did not abuse its
    discretion by so limiting their testimony.
    Rheinfrank’s arguments to the contrary, moreover, are without merit.           Rheinfrank
    appears to contend that the district court’s ruling excessively limited these experts’ testimony by
    making the question of “adequacy” into a “regulatory matter,” thus prejudicially excluding their
    other opinions as to the “adequacy” of Depakote’s label in a wider, non-regulatory sense. But
    that is a misstatement of what the district court ruled. As the district court explained in limiting
    Privitera’s testimony:
    Dr. Privitera is not qualified to opine on the regulatory aspects of the case,
    including whether Abbott was required to send a patient package leaflet directly
    to patients or whether Abbott's submissions to the FDA should have included
    certain materials. Similarly, testimony about what Defendants should have
    included in the label or what materials should have been submitted to the FDA
    falls outside the scope of his expertise, as it falls under the regulatory component
    -16-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    and is speculative. Thus, Dr. Privitera also may not testify about whether
    Depakote should have been contraindicated for all women of childbearing years.
    The court placed much the same limitation, moreover, on Saal’s and Buncher’s testimony, ruling
    that they could not testify as to “what ‘should’ have been in the 2003 Depakote label and
    whether Depakote ‘should’ have been contraindicated for women of childbearing years, as this
    assumes regulatory knowledge.” In no case, that is, did the court exclude these experts’ opinions
    as to the “adequacy” of Depakote’s label from the point of view of their respective medical
    expertise, but only from the point of view of the label’s regulatory adequacy. In fact, Privitera
    was allowed to “opin[e] on the medical facts and science regarding the risks and benefits of
    Depakote” and was likewise able to “compar[e] that knowledge with what was provided in the
    text of the labeling,” and he did so. Similarly, both Saal and Buncher were allowed to “testify as
    to the medical facts and science” and likewise were able to “compare that information and data
    with the language of the 2003 Depakote label,” and they did so. Thus the limitation the district
    court placed on each of these experts’ testimony as to the “adequacy” of Depakote’s label was
    itself limited, and only to the regulatory aspects of the labeling. As explained, that limitation
    was reasonable enough to fall within the “considerable leeway” of discretion that has been
    confided to the district court when making such rulings, see Meridia Prods. Liab. Litig. v. Abbott
    Labs., 
    447 F.3d 861
    , 868 (6th Cir. 2006) (quoting Kumho Tire Co. v. Carmichael, 
    526 U.S. 137
    ,
    152 (1999)).
    Rheinfrank also challenges the limitation placed on her regulatory expert, Dr. Parisian,
    who was not permitted to testify “that as of 2003, Depakote was known to be the most
    teratogenic drug.”   But this limitation also was reasonable and therefore not an abuse of
    discretion. The district court concluded that Parisian was not qualified to give that testimony
    because even though she had an extensive background as an FDA Medical Officer and is a
    -17-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    medical doctor, she is “not a teratologist and does not have any specialized knowledge or
    experience in evaluating [antiepileptic drugs],” 
    id.
     The court concluded that such a specific
    opinion as to the teratogenic effects of Depakote relative to other antiepileptic drugs therefore
    “falls outside the scope of her expertise,” limited as that is by her regulatory background with the
    FDA and as a physician without any specialized understanding or expertise in antiepileptic
    drugs. As Rheinfrank appears to concede, Parisian is no specialist in teratology and therefore
    has no more specialized or expert understanding of antiepileptic drugs than any other licensed
    physician. The court could therefore reasonably conclude that her opinion about the relative
    teratogenicity of Depakote exceeded her expertise. As that is all we have required to uphold a
    ruling like the one the district court made here, see Rye, 
    889 F.2d at 101
    , that decision was not an
    abuse of discretion.
    But even if the district court did err by so limiting Parisian’s testimony, that error was
    harmless. First, Rheinfrank was in fact able to elicit testimony at trial from Parisian that covered
    the relative teratogenicity of Depakote, the very testimony the exclusion of which Rheinfrank
    now claims prejudiced her case:
    Q: And as of this time on August 30, 2002, did the Depakote label contain
    information that the risk of malformations was higher with Depakote than with
    other AEDs?
    A: No.
    Q: And is that what information was included in the report from Dr. Holmes to
    Abbott?
    A: Yes.
    Even apart from Parisian’s testimony, moreover, Rheinfrank was able to elicit the same
    testimony from her other two experts, Privitera and Buncher, who each testified to the higher
    teratogenicity associated with Depakote relative to other AEDs. This court has indicated that
    where “the substance of the excluded testimony [is] furnished by other witnesses,” that exclusion
    -18-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    is not prejudicial. Hines v. Joy Mfg. Co., 
    850 F.2d 1146
    , 1153 (6th Cir. 1988). Thus, even if the
    district court erroneously limited Parisian’s testimony, that error would not have been
    prejudicial. Nor, as a result, would it warrant reversal. See McCombs v. Meijer, Inc., 
    395 F.3d 346
    , 358 (6th Cir. 2005).
    III.
    Rheinfrank next contends that she is entitled to a new trial because the district court erred
    in rejecting four jury instructions that she requested, resulting in confusion for the jury and
    prejudice to her case. But because the instructions that the court did give either substantially
    covered Rheinfrank’s requested instructions or did not prejudice Rheinfrank’s case in any event,
    the court’s refusal to provide those four instructions does not amount to reversible error, see
    Decker, 770 F.3d at 396.2 Those rulings, reviewed for an abuse of discretion, Cummins v. BIC
    USA, Inc., 
    727 F.3d 506
    , 510 (6th Cir. 2013), therefore do not warrant a new trial.
    Rheinfrank argues that the district court erred by refusing to give her three instructions
    relating to the manufacturer’s standard of care and knowledge (No. 7) and requirements for drug
    labeling (No. 8) and adding safety warnings (No. 11) under federal law, because all three were
    correct, and their omission confused and misled the jury and thus were prejudicial. But as the
    district court explained as to Rheinfrank’s requested Instructions No. 7 and 11, both were
    partially incorporated into the instruction the court actually gave. Moreover, at least two of the
    three differences that Rheinfrank cites between the given instruction and the two she requested
    (Nos. 7 and 11)—that the given instruction failed to explain what would make a label inadequate
    under federal law and did not identify the procedures by which the manufacturer would update
    2
    Under this court’s standard for reviewing a district court’s refusal of a jury instruction, such a decision is
    “reversible error if (1) the omitted instruction is a correct statement of the law, (2) the instruction is not substantially
    covered by other delivered charges, and (3) the failure to give the instruction impairs the requesting party's theory of
    the case.” Decker, 770 F.3d at 396 (internal quotation marks and citation omitted).
    -19-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    its labels—do not amount to substantial departures from the given instructions, which made clear
    the gist of those procedures, and explained what would make a prescription drug warning
    adequate.       Although Rheinfrank believes those explanations were deficient, for not having
    indicated “what ability Abbott had to change its label should it become inadequate,” in fact the
    given instruction made that ability clear, at least implicitly:
    a drug manufacturer bears the ultimate responsibility for the content of its label at
    all times. It is charged both with drafting an adequate label and with ensuring that
    its warning remain adequate as long as the drug is on the market.
    Abbott could hardly bear the duty of maintaining the adequacy of its label if it lacked the power
    to effect those changes. Moreover, the same compliance instruction explained, in relation to
    Depakote’s Black Box warning, that “[t]he manufacturer may make suggestions, but the FDA
    makes the ultimate determination regarding the content of the Black Box warning”—implying,
    once again, that Abbott had at least some ability under federal law to amend its labeling. As the
    given instructions substantially covered Rheinfrank’s requested Instructions No. 7 and 11, the
    district court did not err by excluding them as separate instructions, see Decker, 770 F.3d at 396.
    Furthermore, Rheinfrank’s requested instruction on the federal requirements for drug
    labeling (No. 8), which would have further defined the “adequacy” of a “label” under federal
    law, also substantially overlapped with the given instruction on the adequacy of prescription drug
    warnings. Indeed, if anything, the adequacy instruction given by the court was more detailed
    than the one Rheinfrank herself proposed.3 Ultimately, the only substantive differences between
    3
    The “Adequacy of Prescription Drug Warning” instruction reads:
    You may find a warning to be unreasonable, hence inadequate, in its factual content, its expression
    of the facts, or the method or form in which it is conveyed. The adequacy of such warnings is
    measured not only by what is stated, but also by the manner in which it is stated. A reasonable
    warning not only conveys a fair indication of the nature of the dangers involved, but also warns
    with the degree of intensity demanded by the nature of the risk. A warning may be found to be
    unreasonable in that it was unduly delayed, reluctant in tone or lacking in a sense of urgency.
    -20-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    the requested Instruction No. 8 and those the court gave come down to the omitted definition of a
    “label” and Rheinfrank’s proposed definition of “misbranding.”                     But as the district court
    explained, including those details—which were not supported by any Ohio authorities—would
    only have confused the jury, especially as misbranding did not appear to be a focus of the
    testimony at trial. In any event, Rheinfrank has given no reason to believe that the exclusion of
    the definition of a “label” from the court’s instructions prejudiced her case. On the contrary,
    even though the proposed definition would have made clear that promotional and other
    marketing materials were also “labelling,” in addition to the label that was clearly addressed at
    trial, Rheinfrank’s own physician explained that those materials did not figure in her decision to
    prescribe Depakote to Rheinfrank. Given, then, that Rheinfrank’s requested Instruction No. 8
    either overlapped in large measure with instructions given by the court or was otherwise not
    prejudicially excluded, the district court did not err by rejecting it as a separate instruction, see
    Decker, 770 F.3d at 396.
    Rheinfrank also contends that the district court erred by refusing to give her requested
    Instruction No. 14, which would have provided a separate strict liability charge for “post-market
    warning/instruction,” because, Rheinfrank claims, the instruction given by the court failed to
    explain adequately that “the manufacturer’s duty is the same both before and after the product
    leaves its control.” But there are two independently fatal flaws in Rheinfrank’s claim. First, as
    with the other instructions Rheinfrank requested, the instructions given by the district court
    Rheinfrank’s requested Instruction No. 8 reads, in relevant part:
    Directions for use and warnings are inadequate if they are misleading based on what the
    manufacturer said, how the manufacturer said it, or what the manufacturer did not say. If the
    labeling for a prescription drug does not contain such adequate directions for use and warnings,
    the drug is misbranded. Similarly, if a drug is dangerous to health when used in the dosage,
    manner, frequency, or duration prescribed, recommended, or suggested in the labeling, the drug is
    misbranded.
    The sale of misbranded prescription drugs is unlawful.
    -21-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    already covered, not just substantially but entirely, her requested Instruction No. 14. As noted,
    the court gave an instruction that made clear that “a drug manufacturer bears the ultimate
    responsibility for the content of its label at all times,” and that it must “ensur[e] that its warning
    remain[s] adequate as long as the drug is on the market.” Indeed, the given instruction on the
    strict product liability failure-to-warn claim further explained that “[t]he manufacturer has the
    duty to remain reasonably current with scientific knowledge, development, research, and
    discoveries concerning the product,” and that, consequently, it “must communicate its superior
    knowledge to those who, because of their own limited knowledge and information, would
    otherwise be unable to protect themselves.” Read as a whole, as jury instructions must be, see
    Pivnick v. White, Getgey & Meyer Co., LPA, 
    552 F.3d 479
    , 488 (6th Cir. 2009), these
    instructions made clear that what Rheinfrank had proposed in her requested Instruction No. 14
    was already covered by the instructions given by the court: Abbott had a duty to maintain the
    accuracy of its label at all times, even after Depakote had gone on the market and after the doses
    of the drug that Rheinfrank took had left the factory. That overlap is enough to clear the district
    court of any accusation of error, see Decker, 770 F.3d at 396. But even if the district court had
    erred in rejecting Rheinfrank’s Instruction No. 14, she confronts still another difficulty with her
    claim: by failing to object during the charge conference and before jury deliberations, that
    objection is now forfeited, Howe v. City of Akron, 
    723 F.3d 651
    , 660-61 (6th Cir. 2013) (citing
    Fed. R. Civ. P. 51(c)(1)). In either case, then, Rheinfrank cannot succeed on her claim that the
    district court abused its discretion by refusing to give her requested instruction.
    The question submitted by the jury during deliberations does not alter this conclusion.
    Rheinfrank contends that once the jury asked about the meaning of “left the control of the
    manufacturer,” it became clear that the jury had mistakenly believed that “the timing of when
    -22-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    Depakote’s label left Abbott’s control” bore on the company’s liability. Thus, Rheinfrank
    argues, once the jury expressed its confusion on this “key instruction,” under Reynolds v. Green,
    
    184 F.3d 589
    , 594 (6th Cir. 1999), her right to raise an objection was revived and her original
    requested Instruction No. 14 became proper. As the district court explained, however, the same
    fact that distinguished Reynolds also made Rheinfrank’s proposed instruction inappropriate as a
    substitute: the very language apparently at the root of the confusion over the court’s instruction
    (“left the control of the manufacturer”) also appeared, nearly verbatim, in Rheinfrank’s requested
    Instruction No. 14 (“[a]fter Depakote left Defendants’ control”).         Thus the district court
    concluded not only that Reynolds was inapplicable, but, more importantly, that swapping in
    Rheinfrank’s instruction would add nothing but more confusion for the jury, failing as it did to
    answer the question they posed in the first place. Even assuming that Rheinfrank’s objection
    was not waived, then, her proposed instruction would still have failed to cure the jury’s
    confusion and would arguably have compounded it. It was therefore not error—and thus not an
    abuse of discretion—for the district court not to give Rheinfrank’s requested Instruction No. 14
    even in the face of the jury’s question.
    IV.
    Rheinfrank further contends that the district court erred in granting summary judgment on
    Abbott’s preemption defense against Rheinfrank’s failure-to-warn claim, because genuine issues
    of material fact remained as to whether the FDA would have approved a developmental delay
    warning prior to M.B.D.’s suffering the injuries she did in utero. This error, Rheinfrank argues,
    also entitles her to a new trial. But because the evidence in the record reveals that the FDA twice
    rejected Abbott’s attempts to strengthen Depakote’s label to add a developmental delay warning,
    there was clear enough evidence under Wyeth that the FDA would not have approved any such
    -23-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    change in Depakote’s label.             The district court’s grant of summary judgment on Abbott’s
    preemption defense, reviewed de novo, see Int’l Union v. Cummins, Inc., 
    434 F.3d 478
    , 483 (6th
    Cir. 2006), was therefore proper.
    Because the FDA twice refused Abbott’s attempts to strengthen Depakote’s label, based
    on its own review of the evidence that the drug adversely affected the development of children
    exposed to it in utero, Rheinfrank’s failure-to-warn claim is preempted by federal drug labeling
    law. In Wyeth, the Supreme Court reaffirmed the “central premise of federal drug regulation that
    the manufacturer bears responsibility for the content of its label at all times,” requiring the
    manufacturer to “craft[] an adequate label” and to “ensur[e] that its warnings remain adequate as
    long as the drug is on the market.” 
    555 U.S. at 570-71
    . However, because the FDA also has the
    authority to reject any labeling changes—under both its unilateral “Changes Being Effected”
    (CBE) and its “Prior Approval Supplement” (PAS) regimes4—the Court also indicated that the
    manufacturer could “show by ‘clear evidence’ that the FDA would have rescinded any change in
    the label and thereby demonstrate that it would in fact have been impossible to do under federal
    law what state law required.” PLIVA, Inc. v. Mensing, 
    564 U.S. 604
    , 624 n.8 (2011) (citing
    Wyeth, 
    555 U.S. at 571
    ). But the only way the FDA can “rescind” a proposed label change is
    either by rejecting it after it has been added through a CBE supplement, see 21 C.F.R.
    4
    As this court has explained these two labeling-modification regimes:
    After initial approval of a drug, branded-drug companies may seek modification of their labeling
    in two ways: first, through a “Prior Approval Supplement,” which requires submission to and
    approval by the FDA prior to distribution of the product, and applies to most labeling and other
    changes with “potential to have an adverse effect on the identity, strength, quality, purity, or
    potency of the drug product,” 
    21 C.F.R. § 314.70
    (b), and second, through a “Changes Being
    Effected” (CBE) supplement, which must be submitted 30 days before distribution, but does not
    require prior FDA approval.

    id. at 314.70(b). Together Wyeth and Mensing therefore indicate that “a court cannot order a
    drug company to place on a label a warning if there is ‘clear evidence’ that the FDA would not
    approve it.” Robinson v. McNeil Consumer Healthcare, 
    615 F.3d 861
    , 873 (7th Cir. 2010). That
    evidence would be clear enough, moreover, in cases where the FDA has rejected a proposed
    label modification in a “submission to which the agency was responding”—such as in response
    to a PAS.

     That makes sense, as the Seventh Circuit concluded in Robinson, for “it would be
    odd to think” that a manufacturer “had a legal duty to guarantee against a risk that the FDA
    thought not worth warning against.”

    In this case, because Abbott has produced precisely that kind of evidence Abbott has met
    its burden under Wyeth’s clear-evidence standard. In its email response to Abbott’s 2005 PAS
    submission, the FDA made clear that a developmental delay warning “should not be incorporated
    into [Depakote’s] labeling”—a response that even Rheinfrank has characterized as a rejection by
    the FDA of the proposed labeling. Two years later, moreover, in response to another request for
    advice from Abbott, the FDA’s Dr. Katz once again explained that “the data do not provide
    sufficient evidence to support [Depakote] labeling changes at this time.” Indeed, the FDA would
    only approve Abbott’s proposed developmental delay warnings in 2011—some six years after
    Abbott first suggested them. Given, then, that as of 2008 the FDA did not believe the state of the
    data supported a developmental delay warning, it stands to reason that as of 2003, with even less
    data to go on, the FDA would similarly have rejected a developmental delay warning—even a
    CBE, judged as that is by the same standard as a PAS, see 21 C.F.R § 314.70(c)(6)(iii)(A).5 It

    Rheinfrank contends, based on one of Abbott’s FDA contact reports dating from November 2005, that the FDA
    had in fact approved a CBE adding a developmental delay warning. But as the district court explained, the FDA
    contact report in question—stating that the “FDA was in agreement with the latest wording provided to them
    regarding . . . developmental delay”—appears to have been referring to a revision that Abbott made to its 2005 PAS
    -25-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    would accordingly have been impossible for Abbott, prior to M.B.D.’s injury in 2003-2004, to
    comply with Ohio’s product liability law to provide warnings about developmental delay while
    respecting the FDA’s apparent unwillingness—and their authority not—to accept them. Under
    Wyeth, that is enough for federal law to preempt a failure-to-warn claim raised under state law.
    Rheinfrank raises a series of objections to this conclusion, but none is persuasive.
    Rheinfrank first contends that the evidence Abbott provided showing that the FDA would have
    rejected any change to Depakote’s label was too informal to be binding, and thus, under Wyeth,
    was too little and too “fleeting” to constitute clear evidence that the FDA would not have
    accepted a proposed label change, under either the CBE or PAS regime for label modification.6
    But the Court in Wyeth did not say that for evidence to be clear it must result from a formal
    procedure of approval or disapproval. Indeed, to require as much would appear to require
    rewriting the Court’s chosen test—from whether “the FDA would not have approved a change”
    to a drug’s label under a CBE or PAS to whether the FDA had not approved it. Wyeth, 
    555 U.S. at 572
     (emphasis added). As the Court has since clarified, given the FDA’s authority to rescind
    any unilateral CBE, all that Abbott need have done—and did do here—is show that “the FDA
    would have rescinded any change in the label,” Mensing, 
    564 U.S. at

    does not appear to exclude the kind of informal communications from FDA higher-ups that
    Abbott provided.
    earlier that summer at the FDA’s request. Indeed, the next sentence makes that clear: “[The FDA officials] noted
    that we [Abbott] had removed a sentence about developmental delay from the Patient Information Leaflet, and said
    that was OK.”

    Rheinfrank questions the admissibility of Abbott’s internal contact reports with the FDA, which supply the only
    evidence that Dr. Katz had twice made clear that the FDA did not think labelling about developmental delay was
    appropriate in 2008 or 2009. But Rheinfrank does not appear to have raised the evidentiary challenge below or in
    her opening brief, nor was it considered by the district court. As a result, those arguments must be deemed forfeited,
    at least absent some showing of a “gross miscarriage of justice.” Wiley v. United States, 
    20 F.3d 222
    , 226 (6th Cir.
    1994). Rheinfrank has not made that showing here.

    Furthermore, Rheinfrank misreads Wyeth for her claim that unless communications
    between a drug manufacturer and the FDA occur under formal channels, they would be too
    “fleeting” and insufficiently “final” to qualify as “clear evidence.”   As the Court instead
    explained, the real problem with Wyeth’s claim—that “the FDA intended to prohibit it from
    strengthening the warning about” its pharmaceutical—was that there was “no evidence in [the]
    record that the FDA or the manufacturer gave more than passing attention to the issue”
    surrounding the proposed warning.      Wyeth, 
    555 U.S. at 572
     (emphasis added and internal
    quotation marks omitted).    Here, by contrast, there is considerable evidence in the record
    showing that Abbott followed up on new data surrounding developmental delay and Depakote,
    that Abbott contacted the FDA multiple times to propose modifications to reflect that data, and
    that each time officials from the FDA unit responsible for reviewing those modifications
    unequivocally stated that they were inappropriate at the time. As these communications reveal
    more than the “passing attention” that the Court agreed left Wyeth’s claim wanting, and as all
    make clear that the FDA would have rejected the proposed change to Depakote’s label, they are
    clear enough to satisfy Wyeth’s standard.
    Rheinfrank nevertheless contends that, even if the FDA signaled that it would not have
    approved a stronger developmental delay warning on Depakote’s label, a finding of “clear
    evidence” would still be precluded, either because Abbott misrepresented the state of the
    evidence to the FDA in its communications about its proposed labelling changes, or because
    there was evidence about Depakote’s effects on developmental delay that Abbott should have
    known but failed to obtain. Each of these arguments, however, is unavailing. First, even if the
    evidence that Abbott submitted was as misleading or incomplete as Rheinfrank alleges, the
    evidence in the record establishes that the FDA undertook its own review of the relevant
    -27-
    No. 16-3347,Rheinfrank v. Abbott Laboratories, Inc.
    empirical literature apart from Abbott’s various analyses.7 It was that review, moreover, that
    ultimately led Dr. Katz to conclude “that [the FDA was] not yet ready to ‘sign off on labeling
    language’” concerning developmental delay,” and that the FDA “would not take action [on
    Abbott’s submitted CBE] until the review of the data was complete.” Thus, whatever may have
    been Abbott’s omissions or misrepresentations in its communications with the agency, the FDA
    clearly explained that, in its own view of the data, the developmental delay warning that Abbott
    had proposed was not yet warranted. As explained, that evidence is also clear enough to satisfy
    Wyeth’s standard.
    Rheinfrank further argues that Wyeth makes relevant to a “clear evidence” inquiry not
    just what Abbott knew but also what it should have known, and that under that standard Abbott
    fell well short of its responsibility under federal labeling law by refusing to fund or conduct
    studies probing Depakote’s effects on developmental delay. But this argument is too conjectural
    to defeat preemption. As the Court has explained, speculation as to what “a third party or the
    Federal Government might do” that would “make[] it lawful for a private party to accomplish
    under federal law what state law requires of it” cannot thwart a claim of preemption, as evidence
    of that kind would make “most conflicts between state and federal law illusory,” and thus
    “render[] conflict pre-emption all but meaningless.”                 Mensing, 
    564 U.S. at 620-21
    .             That,
    however, is exactly what Rheinfrank asks this court to accept: a series of speculations as to what
    the FDA could have done with different evidence that Abbott might have collected if it had run
    its own studies. Because such speculations are not enough to undermine the clear evidence that

    Rheinfrank also challenges the admissibility of this evidence, but she does not appear to have raised this objection
    below or in her opening brief, nor was it considered by the district court. As a result, this challenge, too, must be
    deemed waived. See Wiley, 
    20 F.3d at 226
    ; Kuhn v. Washtenaw County, 
    709 F.3d 612

    the FDA would have rejected a strengthened warning on Depakote’s label prior to M.B.D.’s
    injury, Rheinfrank’s failure-to-warn claim is preempted by federal law.8

    We therefore affirm the district court’s grant of summary judgment and its denial of a
    new trial.

    Because the district court properly denied Rheinfrank’s motion for a new trial, we need not reach her claim for
    punitive damages.
