Oseltamivir induced oral-only erythema multiforme

Steven Siemieniak et al. Am J Emerg Med. 2022 May.

Abstract

Severe dermatologic and mucosal adverse reactions to oseltamivir are rare. To date, only two other case reports have described mucosal changes secondary to oseltamivir, but both cases were associated with concomitant skin changes. We report a case of a previously healthy 18-year-old-male who developed oral-only erythema multiforme after being treated with oseltamivir for influenza B. Given the frequency of which oseltamivir is prescribed, we highlight the importance of recognizing this uncommon but serious adverse reaction.

Keywords: Erythema multiforme; Oseltamivir; Stevens-Johnson syndrome; Tamiflu; Toxic epidermal necrolysis.
