<<Disclaimer: Verify this information before applying it to your situation.>> For those of you who want to know "what else" is in prescription medications, I just located a website for family physicians which contains monographs for lots of prescription medications. The two I looked at, Estrace and Provera, both included a complete list of "what else" is in the pills: cornstarch, colorings, etc. It says, for instance, that several dosages of Provera are gluten-free. While I wouldn't consider this necessarily the latest information because we know that ingredients change (both monographs I looked at were dated 1996), and while you should probably check ingredients with your pharmacist, it is perhaps a place to start.
