I thinks its morphine, its purple small round tablet, M with a square around it on one side and 30 on the other, is this morphine sulphate, or MS Contin? anyone, and a quick reply would help thanx.
From RxList: Imprint Code: M 30 Drug/Strength/Manufacturer: MS Contin 30 mg - Purdue FrederickDescription: purple round tablet This may not be 100% accurate, you might want to try searching for the manufacturer on google images and see if you can find a picture.
anyone else, the only thing about it is MS Contin usually says, MS PF 30 or whatever size it is, this is just and M with a sqare around it.
