I get my prescribed meds by mail order. Recently there was an extra bottle in with mine, containing Aricept 10mg tablets. The generic name is donepezil. I called my mail order pharmacy and asked them how to mail it back, but they never gave me an answer and that was several months ago now so I have given up. I know that this is used for Alzheimer's disease patients, but does it have any other use? Should I just throw it out, or what? Thanks!
