Hydrochlorothiazide vs Venlafaxine: Drug-induced Bullous Pemphigoid

Abstract

Pemphigoid group of dermatologic conditions is a group of autoimmune skin disorders resulting in blistering skin conditions. The two diseases that fall under this category are bullous pemphigoid and pemphigus vulgaris. While there are many similarities in these two disorders, there are numerous pathologic and biochemical differences which help us differentiate between these disorders. In this case report, we report a usual manifestation of bullous pemphigoid in a 72-year-old female secondary to use of a well-known antihypertensive (hydrochlorothiazide) and/or venlafaxine (anti-depressant).
