Clindamycin is an antibiotic used to treat various bacterial infections. It works by inhibiting the growth of bacteria, making it effective against certain types of infections, including those of the skin, respiratory tract, and soft tissues. Clindamycin is available in different forms, such as capsules, topical gels, and injections. This medication is often prescribed when patients are allergic to penicillin or when the bacteria are resistant to other antibiotics. Common side effects may include stomach upset, diarrhea, and skin rashes. It's important to take clindamycin exactly as directed by a healthcare provider to ensure its effectiveness.
