However, therapy with either trimethoprim-sulfamethoxazole or pentamidine carries substantial risks of severe side effects (2). Because dapsone (4,4′-diaminodiphenylsulfone) has been effective in a rat model of pneumocystis infection (3), we studied its safety in patients with AIDS who have previously had severe reactions to trimethoprim-sulfamethoxazole.
Four patients were closely monitored while they received 25 to 200 mg of drug daily for up to 1 year. All were initially screened for glucose-6-phosphate dehydrogenase deficiency. Patients were begun on
