<<Disclaimer: Verify this information before applying it to your situation.>> For osteoporosis: I had trouble taking Fosomax and stopped it. It is gluten-free,...at least it was when I was using it last year. I'm also on Prempro and want to stop taking that, so the doctor recommended Evista for the bones. (Not sure of spelling.) I phoned the Eli Lilly company today and was told it is gluten-free. (800-545-5979) When I gave the person at Eli Lilly just my name, she pulled up my home phone number (not caller I.D....I was not calling from home.) They do keep track of our phonecalls, folks....and I'm increasingly impressed with their reactions to inquiries about celiac and gluten-free products. When we as individuals call them, it makes a difference. Linda
