Clindamycin, which was first made in 1966, is an antibiotic that works by stopping bacteria from producing the protein they need to reproduce and spread infection in your body. Plus, it comes in a number of different forms (capsules, creams, gels, solutions, injection, and more). Clindamycin can be prescribed to treat or prevent many types of infections, such as bone or joint infections, pelvic inflammatory disease, strep throat, pneumonia, middle ear infections, and endocarditis. Additionally, this antibiotic might also be used to prevent an infection in the heart before a dental procedure, especially for people who may be allergic to or unable to take penicillin. As for its side effects, they include nausea, diarrhea, rash, and pain at the site of injection. On a side note, Clindamycin appears to be generally safe in pregnancy.
