Stibophen (Fuadin),* an organic trivalent antimony compound, has been used for many years in the treatment of schistosomiasis. Many side-effects have been reported, but their occurrence has been infrequent. The more common side-effects have been nausea, anorexia, vomiting, dizziness, joint pains, electrocardiographic changes, eosinophilia, and mild upper abdominal pain. The less frequent side-effects have been fever, maculopapular rash, bradycardia, hypotension, hepatic and renal insufficiency, bone marrow depression, retinitis, and neuritis.1-4

The fourth case5 is the only reported instance noted in which stibophen was demonstrated to be the etiologic agent. Thrombocytopenic purpura was produced in a normal person by administering stibophen
