In prescription and over-the-counter medicines, fillers (also called “inactive ingredients” or “excipients”) are added to the active drug. Fillers provide shape and bulk for tablets and capsules, aid in water absorption (helping the tablet to disintegrate), and serve other purposes as well. Fillers can be derived from any starch source, including corn, potatoes, tapioca and wheat.  Currently there is no law requiring the labeling of gluten in medication.

As a courtesy to the gluten-free community, Dr. Steven Plogsted of Nationwide Children’s hospital maintains a website that provides information regarding gluten-free drugs. This site is for informational purposes only and may contain inaccuracies.  Dr. Plogsted advises that, “All persons should interpret the information with caution and should seek medical advice when necessary.”

Please note: There may be prescription drugs or over-the-counter medications that are gluten-free and are NOT included in his list, so always check with the manufacturer.
