Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, stop using this medication and call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.
Do not receive a "live" vaccine such as typhoid vaccine, cholera vaccine, or BCG (Bacillus Calmette and Guérin) vaccine.
