16880066_sWhen our camp doctors at Camp Celiac in Livermore, CA, try to determine whether a medication a child needs is gluten-free, they are stymied by a lack of information. Federal regulation is insufficient. Examining labels and package inserts, searching the Internet and calling drug manufacturers (if the doctor is lucky and it’s a weekday) may or may not produce an answer. Doctors, pharmacists and patients across the country experience the same challenges with gluten in medication. Public frustration with the Food and Drug Administration’s inaction on this issue is rising.

The Food and Drug Administration (FDA) regulates the gluten-free labeling of foods for health and safety, but in 2015 the agency declined to take actions that would provide comparable protection from gluten in medication. Proposals have included banning gluten from drugs or requiring labeling. The FDA stated that it would address the issue by publishing guidance for drug manufacturers, but did not offer a timeline. Recent developments on the topic of gluten in medication indicate renewed pressure on the FDA to take action.

“This is an important issue that most healthcare providers don’t even realize exists,” said Amy Burkhart, MD, RD., who specializes in celiac disease and gluten-related disorders. “Most physicians assume the pharmacists are well versed in verifying that medications are gluten-free. The truth is that most pharmacists simply read the labels and don’t verify gluten-free status with the manufacturer. We need labeling regulations to streamline the process for pharmacists and ensure that patients on a strict gluten-free diet are able to take their medications without worry and adverse health consequences.”

LEGISLATION

U.S. Representatives Tim Ryan (D-OH) and Nita Lowey (D-NY) reintroduced legislation in September 2015 that would require medication to be labeled with a parenthetical statement identifying the source of any ingredient constituting or derived from a grain or starch-containing ingredient. The bill is titled Gluten in Medication Disclosure Act of 2015 (H.R. 3648)  Similar legislation was introduced in 2012 and 2013, but died in Congress.

CITIZEN PETITION FROM NEW YORK RESIDENT

In June 2008, New York resident Michael Weber submitted a citizen petition asking that wheat gluten in medication be banned or appropriately labeled. Following a lawsuit by Public Citizen regarding the FDA’s “unreasonable delay,” the FDA replied to the petition with a 21-page letter last May.

The petition was “denied in part and granted in part.” The FDA denied the petition in part by declining to ban gluten in medication. It granted it in part with this statement: “Your labeling request is granted in that we affirm our preexisting expectation that any drug product containing wheat gluten as an inactive ingredient should be labeled to indicate its presence.” The FDA’s expectation that gluten be labeled does not carry the force and clarity of regulation and does not match the experience of gluten-free consumers and their medical providers.

44604937_sThe FDA stated that although it does not intend to issue new regulation, it recognizes misconceptions, frustration and anxiety on this topic. To address these concerns, the FDA plans to issue draft guidance for industry (directed at drug manufacturers) regarding gluten in drug products. The guidance would cover a range of topics: the labeling of ingredients using their “common or usual names”; paying attention to potential sources of gluten in drug formulations; making inactive ingredient labeling information readily available when a drug does contain gluten; and voluntary gluten-free labeling of drugs with steps to substantiate such labeling.

Michael Weber continued the dialogue by sending the FDA a reply letter in December 2015. The Celiac Community Foundation of Northern California collaborated with Mr. Weber in analyzing the FDA’s response to his petition. In his letter, Mr. Weber expressed appreciation for the FDA’s extensive analysis and welcomed its proposed actions, but disagreed with key points.

For example, Mr. Weber questioned the FDA’s assertion that Americans are already “adequately protected” from gluten in medication. As Mr. Weber countered, “If so, then the FDA should be urgently concerned that manufacturers, physicians, pharmacists and consumers alike are frequently mired in uncertainty about whether any one drug contains gluten.” Mr. Weber asked the agency to respond with a timeline for the actions it proposed on this topic, including its planned “broader analysis of gluten and publication of draft guidance.”

CITIZEN PETITION FROM CALIFORNIA RESIDENTS

A second citizen petition was filed in December 2015 by eight board members of the Celiac Support Group in Sacramento, California, following the FDA’s disappointing response to Mr. Weber’s petition. The group reviewed the history and scope of gluten in medication issues and, as individuals, filed a 19-page citizen petition to propose labeling medications when more than 20 ppm gluten is present. The petition argued that its proposed rule would “protect celiacs…without imposing burdens on medication manufacturers or the FDA.”  On December 31, 2015, the FDA posted the petition and opened it for comments.

BACKGROUND

Gluten may be used as an inactive ingredient in medication (as a starch known as an excipient that binds medication), and the FDA does not currently require it to be labeled in prescription drugs. Gluten in medication is rare. However, without labeling and with a very low level of understanding of the issue among doctors, pharmacists, patients and even drug manufacturers, it is often difficult or impossible to tell if gluten is present in a medication.

“Healthcare providers should be able to easily determine if a medication is gluten-free, but we often cannot,” said Camp Celiac volunteer physician Amy Burkhart, MD, RD

The question of whether a medication contains gluten is often unresolved at key points in the supply chain and among patients: when a doctor prescribes a medication, when a pharmacist is considering contraindications, when an inquiry is made to the drug manufacturer, when a person with a gluten-related disorder needs to buy and take a medication, or when a parent needs it for their child. The information is unavailable, ambiguous, contradictory or so elusive that it requires extensive research beyond the resources of medical professionals or patients.

Gluten triggers an autoimmune reaction in people with celiac disease, causing short-term misery and long-term harm; it is poison to this segment of the population. Drug safety for all members of the public, including disease subpopulations, is a primary aspect of the FDA’s mission. The FDA requires a clear warning on medications that contain phenylalanine because it is toxic to the 14,500 Americans with the rare disorder phenylketonuria (PKU), while disregarding the needs of hundreds of thousands of Americans living with celiac disease and gluten-related disorders.

TAKE ACTION

The proposed legislation and citizen petitions are asking the FDA to do its job in ensuring the safety of the drug supply for all Americans, including those with gluten-related disorders. National organizations supporting the legislation, including the Celiac Disease Foundation and Beyond Celiac, are following the issue closely as it develops. Members of the public can take action in support of efforts to ban or label gluten in medication:

Legislation: The Celiac Disease Foundation’s Legislative Action Center offers a simple and fast way to send an email to Congress in support of the Gluten in Medication Disclosure Act of 2015.

Citizen Petition: Public comments are carefully considered by the FDA, which often references and responds to comments in its final documents. In addition, comments are posted on the FDA website and contribute to the national discussion. The comment period for the first citizen petition is closed, but comments on the second one may be submitted until June 27, 2016.
