Is My Medicine Gluten-Free?
Look up the inactive ingredients on public FDA DailyMed labels for the medicines families actually keep in the cupboard — pain and fever relievers, antibiotics, allergy medicine, reflux, inhalers, and more.
Celiac disease means every swallowed excipient matters, and the ingredient list is the only honest place to start. This tool shows you what the label says, flags the ingredients that carry gluten risk, and hands you the exact questions to ask before you fill the prescription.
Search by brand or generic name — or by an ingredient you want to check.

Ask the AI lookup
For a medicine that is not in the snapshot, the AI lookup explains which inactive ingredients are worth checking and what to ask your pharmacist. It reads general knowledge, not a specific label.
How the flags work
- The scan reads the inactive-ingredient elements and the inactive-ingredient section of each public FDA DailyMed label.
- It flags wheat, wheat starch, wheat gluten, barley, rye, malt (but not maltodextrin), and any “starch” that is not qualified as corn, potato, tapioca, or rice.
- No flag does not mean certified gluten-free. Most oral medicines use corn-, potato-, or rice-derived starch, but wording on a label can still be ambiguous — that is exactly what a pharmacist is for.
- Excipients change by manufacturer and NDC even when the active ingredient is identical, so match the exact package in your hand.
Before you fill a prescription
A flagged ingredient is a question, not a verdict. Plenty of medicines that mention “starch” are made with corn starch, and some manufacturers will confirm the source of an excipient in writing if you ask. The fastest reliable path is still your pharmacist: they can read the manufacturer's package insert, call the company, and tell you whether a gluten-free version of the same drug exists.
For the wider picture — including how the FDA approaches gluten in medications and why “gluten-free” on a drug label is not a regulated certification the way it is on food — see the FDA's guidance on medications and gluten.
Sources and how this is built
- Label data comes from the DailyMed SPL API from the U.S. National Library of Medicine.
- Every result links back to its DailyMed label so you can read the original source yourself.
- The AI lookup runs on Abacus AI's DeepSeek router and gives general guidance only — it never reads a specific label and never certifies a product.
Not a gluten-free certification. Confirm with your pharmacist.
