Making sure my medications are gluten free is one of those things that I always find to be a little tricky. I've been on hold with a few pharmaceutical companies for quite awhile trying to make sure my daughters and my prescriptions are gluten free. I found this drug list that has been really helpful. It isn't all inclusive, but it is a great start! I'm also partial to Target brand for over the counter medications since they label their products.
