Hey I was wondering what is mepergan?? I have some left from a while back. I have hears its demoral and that demerol is not an opiate, is that true. Please tell me all you can about this drug?

Mepergan is a combination of meperdine and promethazine...or demerol and phenergan in more familar terms. Demerol, or meperdine hydrochloride, is a powerful opiate usually given in injection form but can also come in oral pills. Be very careful with this stuff.
