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 for patients who are allergic to penicillin or when other antibiotics are not suitable. Common side effects may include stomach upset, diarrhea, and skin rashes. It's important to complete the full course of treatment as directed by a healthcare provider to prevent antibiotic resistance.
