Gluten Screen

Printable handout

A card to hand your pharmacist

“Is this gluten-free?” is a question almost no pharmacist can answer from the counter. These three can be. Print this, fill in your details, and hand it over.

Celiac disease — medication request

glutenscreen.org/pharmacy-card
Patient:   Date:
Medication:   NDC on the bottle:

I have coeliac (celiac) disease and follow a strict gluten-free diet for medical reasons. I am not asking you to certify this medication as gluten-free. I am asking three specific questions:

  1. Does this product contain a starch excipient, and does the label name its botanical source? Corn, potato, tapioca and rice starch are fine. An unqualified “starch” or “pregelatinized starch” does not say which, and that is what I need resolved.
  2. Which labeller or manufacturer is this specific fill from? Different labellers of the same molecule use different excipients, so the answer is tied to the NDC in the bottle, not to the drug name.
  3. Can you flag my file so I am told if the generic changes? If the pharmacy switches suppliers at a future refill, the inactive ingredients can change without the prescription changing. I would like to re-check when that happens.

Why it matters: gluten is rare in oral medication and the amounts involved are small, so this is usually a quick reassurance rather than a problem. But a daily medication is a daily exposure, and drug labels are not required to disclose gluten the way food labels are. I would rather ask than assume. I am not asking to stop or change any medication — only to know what is in it.

Pharmacist notes: Not medical advice · glutenscreen.org

Why these three questions

Most gluten-in-medication anxiety dead-ends because the question asked is unanswerable. A pharmacist cannot certify a product gluten-free — no one can, because drug labels carry no gluten threshold the way food labels do under 21 CFR 101.91. But a pharmacist can read you an inactive ingredient list, can tell you which labeller the bottle came from, and can put a note on your file.

The third question is the one people forget and the one that matters most over time. A prescription that was fine for a year can change at a refill because the pharmacy's supplier changed. Nothing about the prescription looks different when that happens.

This card is a communication aid, not medical advice. Gluten Screen is not a pharmacist, physician or dietitian. Never stop, switch or substitute a prescribed medication because of something you read here — bring the question to your care team, which is exactly what this card is designed to help you do.
