Precautions While Using This Medicine:

It is important that your doctor check your progress at regular visits.

In some patients, clindamycin may cause diarrhea.

  • Severe diarrhea may be a sign of a serious side effect. Do not take any diarrhea medicine without first checking with your doctor . Diarrhea medicines, such as loperamide (Imodium A-D) or diphenoxylate and atropine (Lomotil), may make your diarrhea worse or make it last longer.
  • For mild diarrhea, diarrhea medicine containing attapulgite (e.g., Kaopectate tablets, Diasorb) may be taken. However, attapulgite may keep clindamycin from being absorbed into the body. Therefore, these diarrhea medicines should be taken at least 2 hours before or 3 to 4 hours after you take clindamycin by mouth.
  • If you have any questions about this or if mild diarrhea continues or gets worse, check with your health care professional.

Before having surgery (including dental surgery) with a general anesthetic, tell the medical doctor or dentist in charge that you are taking clindamycin.
