African type anti-trypanosomal drug (T.Gambiense, Sleeping disease). Treatment is recommended for 7 days long. There is not any experience with this drug on breastfeeding to make a recommendation. Assess risk-benefit ratio and mother’s condition closely, which is usually precarious. In any case, check-up for side effects on both the mother and the baby. Because of such short-term treatment, a temporally breastfeeding withholding may be scheduled. Melarsoprol is a much less toxic drug, unfortunately, the industry do not regard it as being profitable enough to assure a continuing access of poor patients to the latter drug.
