A Case of Atypical Fixed Drug Eruption Induced by Erdosteine

Abstract

Erdosteine is a mucolytic agent used in acute and chronic respiratory disease and it is known to be well tolerated.Adverse drug reactions related with erdosteine are mostly mild gastrointestinal symptoms and only two case reports of hypersensitivity have been published. Here, we report a case of atypical fixed drug eruption related with erdosteine intake proven by a drug provocation test. Physicians should be aware of the hypersensitivity reaction related to erdosteine, despite its well-known tolerability.
