Fixed drug eruption (FDE) is common type of drug eruption seen in skin clinics. FDE usually occurs within hours of administration of the offending agent. Most commonly implicated are sulphonamides, salicylates, oxyphenbutazones, tetracycline, dapsone, chlordiazepoxide, barbiturates, phenolphthalein, morphine, codeine, quinine and derivatives, phenacetin, erythromycin, griseofulvin, mebendazole, meprobamate etc. We hereby report a case of fixed drug eruption on glans penis due to metronidazole, a nitroimidazole-derivative clinically indicated in trichomoniasis, amebiasis, giardiasis, anaerobic and mixed antibacterial infections. A patient administered metronidazole IV developed erythematous superficial non-tender ulceration over the glans penis on the second day of treatment with Inj. Metronidazole. A provisional diagnosis of metronidazole induced fixed drug eruption was made, metronidazole inj. was stopped and the patient was managed with Tab. Prednisolone 30mg/day tapered over 10 days and Fusidic acid+Betamethasone cream. |
