Abstract

Dapsone (4,4’‑diaminodiphenylsulfone) is the parent compound of the sulfones, and it 
has potent antiparasitic, anti‑inflammatory, and immunomodulatory effects. It is used 
in the treatment of leprosy, dermatitis herpetiformis, and prophylactically to prevent 
Pneumocystis pneumonia and toxoplasmosis in patients unable to tolerate trimethoprim 
with sulfamethoxazole. We hereby report a case of dapsone toxicity who developed pure 
red cell aplasia and cholestatic jaundice in a suspected case of dermatitis herpetiformis. 
Patient had an excellent response to corticosteroids after withdrawal of dapsone.
