Specializes in Infectious Disease

Get checked: Any time you have bad diarrhea after taking antibiotics, or while taking them, you should get checked for clostridium difficile infection, which requires a stool exam. In the meantime, avoid milk products, since having diarrhea can make you temporarily lactose deficient.
