<<Disclaimer: Verify this information before applying it to your situation.>> Thanks to all who responded to my question about whether Levothroid and Asacol were Gluten-free. All of the messages I received (see below for all the responses) said they were indeed GF, so no worries. "They are definitely gluten-free! I take both drugs and my gastro people have put me on Asacol and know about my levothyroid." "Yes, levothroid is gluten free." "I have used levothroid for 9 years and have no problems." "Asacol is still Gluten Free. My pharmacist checks all my meds for me. I am on it right now." And one respondant had some advice too (which I tend to agree with, though asacol did help to heal the symptoms of my colitis): " I was on asacol for awhile, but I couldn't see any difference and it required so many pills per day I stopped taking it. I presume it is GF however since my gastroenterologist prescribed it. I heard a few horror tales about it too, but I am not much for medication. I think it is better just to work through the diet and let your body adjust naturally which may take some time." (Here here) *Support summarization of posts, reply to the SENDER not the Celiac List*
