I'm taking antibiotics along with a probiotic in order to reduce the diahrrea. That's been working and my stool has been normal everyday , except today it looked really dark. Nothing else was abnormal. Could this just be a solitary event?

Dark, tarry stools can be from bleeding high in the digestive tract (such as a peptic ulcer). It can also be from something you've eaten or taken such as beets, licorice, blueberries, dark green leafy vegetables, dark chocolate, Pepto Bismol, iron supplements.

It is probably nothing to worry about. Just keep an eye on it for the next couple of days and if you see red blood, you need to go to your medical provider right away.
