Pneumocystis carinii pneumonia (PCP) occurs in nearly 80% of patients with the acquired immune deficiency syndrome (AIDS) and is a common cause of morbidity and mortality. Oral trimethoprim-sulfamethoxazole (Bactrim; and others), intravenous isethionate (Pentam 300) and other systemic drugs have been used to prevent PCP, but in AIDS patients, all of these agents can occasionally cause severe adverse effects (Medical Letter, 30:94, 1988).
