<<Disclaimer: Verify this information before applying it to your situation.>> If you need to find out if a medicine is Gluten Free here in Australia, there is a company (MIM) that produces a book containing data on all the drugs for the information of Doctors and Pharmacists. They produce a bi-monthly update which is called "MIM's Bi-Monthly" (I think) which lists all ingredients and indicates, apparently, whether or not they are GF. So for all you Coeliac sufferers in Australia, this should be of assistance.
