Most antibiotics can cause some degree of stomach upset like nausea, vomiting, and/or diarrhea. If you have severe diarrhea or diarrhea that lasts for 2 or more days, let your healthcare provider know. Diarrhea is a common side effect while taking antibiotics and just after finishing them. But in some cases, diarrhea from antibiotics can be a sign of a more serious infection caused by Clostridium difficile (C. diff.) bacteria.
