There is currently a black box warning related to itraconazole stating that its use is contraindicated for the treatment of onychomycosis in patients with left ventricular dysfunction or a history of CHF. We report a case of a man presenting with 3 exacerbations of CHF secondary to itraconazole therapy for disseminated histoplasmosis. He was successfully treated with posaconazole with no recurrence of symptoms. From the University of Oklahoma Health Sciences Center, Oklahoma City, OK. Correspondence to: Michelle D.
