Question: what is the strongest antibiotic for skin infection?
Answer: As most cases of uncomplicated cellulitis are caused by Strep, they are still best treated with a penicillin or cephalosporin (e.g., Keflex) type of antibiotic, known as beta-lactams. These antibiotics are much better than TMP-SMX for strep infections. These drugs are also safer than clindamycin, for widespread use.
