Possible 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. False positive results can occur based on diet & stool additives.

What about bleeding?: Given your medications and the history, I would worry about bleeding from your gastrointestinal tract. The black stool may go along with this (unless you are taking a bunch of iron supplements). I would make an appointment to see your regular doctor.
