Urinary schistosomiasis treated with niridazole (Ambilhar): A quantitative evaluation

17 male farmers aged 9–18 years infected with S. haematobium were treated with oral niridazole (Ambilhar). The daily dose was 25 mg. per kg. body weight in divided doses for 6 days. Bell's egg-count technique was used to assess intensity of infection and percentage reduction of egg excretion after treatment. The criterion of cure was the absence of live eggs in the urine 3 months after treatment. All patients were cured, side effects were minimal, and in 5 young patients radiological and functional improvement occurred. It appears that oral niridazole is equal to sodium antimony tartrate in the treatment of S. haematobium infection in young patients.
