Acneiform Rash Caused by an Unlikely Drug: Topiramate

摘要

>Topiramate is an antiepileptic drug that can also be used for migraine prophylaxis, weight control, and even for methamphetamine dependence; the dosage margin is wide, and the list of side effects is shorter than with other anticonvulsants. We present the case of a 35-year-old man with a disseminated rash of the trunk and extremities after treatment with 25 mg of topiramate daily as a prophylactic migraine treatment. This case report is useful, as this patient was not polymedicated and had a score of 7 on the Naranjo Adverse Drug Reaction Probability Scale. The patient was diagnosed as atypical DRESS syndrome and resolved satisfactorily with symptomatic treatment and topiramate withdrawal; slowly, the lesions regressed. He required no further drugs for the dermatologic condition.
