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.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
