The efficacy and acceptability of oral oxamniquine were assessed in Sudanese patients infected with Schistosoma mansoni. Cure rates, determined by the absence of viable eggs in the stools six months after treatment, were 94.9% in patients treated with a total of 60 mg/kg, 78.8% in patients treated with 40 mg/kg, and 68.9% in patients treated with 30 mg/kg. All treatment regimens considerably reduced the egg count in those patients not cured. The drug was well tolerated and the side effects were minimal and transient, the most common being dizziness. Most of the patients noticed a reddish discoloration of their urine, which was probably caused by a metabolite of the drug. In patients who received 60 mg/kg oxamniquine there were transient rises in eosinophil counts and in serum alanine aminotransferase concentrations. Though 60 mg/kg was by far the most effective dose in terms of cure rate, egg counts were significantly reduced on all three doses. The lower doses could therefore be useful in a low-cost control programme in reducing transmission of S mansoni infection.
