I purchased a few of them to use for emergency supplies of some medication I need to take daily. I am interested in finding out about any possible reactions between the pills and the aluminum container. Does anybody know a good source to find this out (Physician's Desk Reference perhaps?). Chemistry wasn't my strong subject in school so something simple like "generally avoid items containing X substances when using aluminum containers" would help. I've avoided listing my medicine to keep this as general as possible.
