<<Disclaimer: Verify this information before applying it to your situation.>> Several people have mentioned using only name-brand prescription medications to assure GF status. I have had good luck with generics. I find out from the pharmacist who manufactures the generic they stock, and usually they can give me the phone number so that I can check. A couple of times I have had to do a web search for manufacturer information, but I have always been successful in getting contact info. The pharmacy uses the same suppliers routinely, and this has saved me having to check each time. Cherie
