Define melena: Melena, by definition, is passage of dark stools stained with denatured blood. As we established in prior healthtap answers, all dark stool is not melena. Your doctor, or even an over-the-counter test that you can purchase, can check to see if your dark stool contains blood. Needed is for you to provide a sample of the dark stool. Be aware that NSAID's can promote stomach ulcers that may bleed.

How dark?: Is is black, tarry or malodorous? If yes, that could be related to blood in stool. Non-steroidal anti-inflammatory medications can be hard on the GI tract. Get seen if that is the case.
