Have small white round pills. One side has the number 381 on the top half then a line through the middle and the number 6 in the bottom half. It is plain on the other side with no center line. Any ideas?
Probably not a 6 but a b for Barr Labs
381 b has been identified as Meperidine hydrochloride 50 mg.
