I found a pill that is small, white, and round, with a boxed M on one side and a 05 52 on the other side I would like to know what it is. I found out the boxed M means mylan pharmaceuticals but that is all I know. Please help? Thank you

Try looking it up on the PDR:
PDRHealth | Prescription Drug Information and Health Information

You found a pill. If you don't know what it is, then why don't you simply dispose of it in a proper manner like taking it to a pharmacist for identification and proper disposal? If people on this site would like to assume the proper identification of it, then I would assume that they would also assume the possible legal responsibility of being incorrect as far as what it might be in case it might be taken internally.

Best to be taking it to a pharmacist for correct identification and proper disposal. No one on this site is properly qualified to help you in the identification of it withlout seeing it in person.

Thanks!
