Clindamycin: Uses, Side Effects, and How to Take It Safely

Published: July 22, 2026Updated: July 22, 2026

Clindamycin is an antibiotic used to treat certain bacterial infections, including some skin, dental, bone, lung, and resistant staph infections. It does not work for viral illnesses such as colds or flu, and the correct dose and formulation depend on the infection being treated.

Quick summary

Take clindamycin exactly as prescribed and finish the full course unless your clinician tells you to stop. Contact a healthcare professional promptly for severe diarrhea, allergic reactions, or signs of liver problems.
