How does this medication work? What will it do for me?
Clindamycin belongs to the class of medications called antibiotics. It is used to treat infections caused by certain types of bacteria. It is also used before dental procedures or surgery to prevent infections in people who have heart conditions that put them at greater risk of infection. Clindamycin kills bacteria by interfering with how they function.

Antibiotic-related diarrhea: As with other antibiotics, clindamycin can cause a severe form of diarrhea associated with a condition known as pseudomembranous colitis. If you develop severe diarrhea while taking (or within a few weeks of taking) this medication, contact your doctor.
Liver disease: People with liver disease should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Overgrowth of organisms: The use of antibiotics occasionally results in the overgrowth of organisms that they don't kill, particularly yeasts that may cause yeast infections. This may lead to conditions such as vaginitis.
Pregnancy: The safety of this medication for use during pregnancy has not been established. This medication should not be used unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking clindamycin, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
