D12 PURPLE PILLS – IDENTIFICATION, MECHANISM OF ACTION, PRECAUTIONS
A purple pill marked with the imprint D12 (specifically stamped M D12) is Doxazosin Mesylate 8 mg, a prescription medication manufactured by Mylan Pharmaceuticals.
(Note: “Purple Pills” is also the title of a famous 2001 hip-hop single by Eminem’s group D12, but medically, the physical purple tablet bearing the code “D12” refers to Doxazosin).
