Fixed Drug Eruption Due to A Cerumenolytic Ear Drop; Hydrogen Peroxide and Boric Acid: A Case Report

Abstract

Treatment of earwax often involves the use of a wax softening agent (cerumenolytic) with or without antimicrobial agents to easily removing. Cerumenolytic agents used to remove and soften earwax areoil-based treatments, water-based treatments. Fixed drug eruption (FDE) is a well-defined, circular, hyperpigmented plaque that usually occurs on the trunk, hands mucosal surfaces, after a systemical application of drugs. In this report, a case with FDE developed after a cerumenolytic agent (hydrogen peroxide and boric acid in water). A definitive diagnosis was made with skin punch biopsy and FDE was treated with oral levocetirizine and topical mometasone.
