Hello, I have a pill with these markings... on one side there is a capitol M in a square box, and on the other side there is 57/71. It is supposed to be a XANAX of unknown mg. I cannot seem to find it on any pill identifying websites. The pill is white oblong and scored... any help would be greatly appreciated! Thanks guys. Bye![]()

Wow, good find phisher. Ive even had those pills so I should have known that.
Thanks for the help guys... I don't want anything to do with methadone so I'm glad I've found a website that has a group of people willing to help and knowledgeable about such things. Thanks again!![]()

The boxed m would be a mallinckrodt product , I dont think they make a generic xanax unless Im mistaking , so it may be something else.
