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.
