It could possibly be an Oxymorphone Hydrochloride extended release 7.5 mg. It is a Narcotic Analgesic and is in the class C for narcotics. It is used for the treatment of VERY severe pain, and is habit forming. You should not take this if it is not prescribed to you. There are many risks associated with this drug. At the very least research this before you take it or you could end up in a very bad situation. and when I say possibly I meant it! so look up a pill identifier on google or something before you go taking something that could potentially put you in the hospital! PLEASE!
