[Penicillin-induced acute renal failure as a rare severe complication of erysipelas treatment].

Penicillins are the most commonly used antibiotics in dermatology owing to their bacteriocidal effect and the high responsiveness of most bacterial dermatoses to penicillin treatment. Although there is a wide range of adverse reactions to penicillins, severe complications are seen very rarely. We report on two cases of penicillin-induced acute interstitial nephritis and summarize the characteristic features of this serious adverse reaction to penicillin administration.
