<<Disclaimer: Verify this information before applying it to your situation.>> Many thanks to all who replied! I checked out your suggestions and here's what I found. http://www.needymeds.com -has a list of drugs and manufacturers contact info. Does not seem to include all drugs, so it's most useful if the one you're interested is on their list, or if you know the name of the manufacturer of what you're interested in. http://www.stokesrx.com-has a book which can be purchased for $39.95 plus shipping (about another $4 or so) with GF info on prescription drugs. Also someone wrote that a phone call to their 800 number can get helpful info. 800-754-5222 Stokes Pharmacy, 639 Stokes Rd. Medford, NJ 08055 http://www.rxlist.com/interact.htm -has a searchable database that lists ingredients, not specifically whether or not GF, but if it says "starch" ...... http://www.geocities.com/naplesceliacs/ has a link to the needymeds drug company address list http://www.longs.com - has an ask the pharmacist email service, replies said to be sent in 1-2 working days. The link is off of the customer service link. Because the meds I was interested in are generic and are each made by several companies, they could not help unless I could tell them exactly which manufacturer had produced the drug in question. http://www.rxmed.com - though I didn't specifically find gluten related info, it has a lot of info, good for things like reactions, etc. aimed at physicians http://www.csaceliacs.org/pharmaceuticals.html - From CSA, looks helpful, drug info guide has whether or not the stuff was positive or negative on gliadin antibody test http://www.medscape.com - suggested by someone for its searchable database of articles including one on Gluten in medications. You have to register (free, but do they then sell your info to a million other companies? I don't know.) http://www.geocities.com/gluten_rx/gluten.html has a list of drugs that claim to be GF, however this list does not always agree with the CSA page list http://www.geocities.com/HotSprings/Spa/4003/gf-index.html - has a link to a medications page and lots of links to info on vitamins and supplements as well http://my.webmd.com - someone suggested, but I was unable to find much on gluten in drugs, however it has other interesting stuff including articles http://www.celiac.com/products.html#Medicines - has a list of GF common OTC and prescription drugs
