Background: Although hydroxycarbamide (hydroxyurea [HU]) has been in use for decades in both adults and child populations with sickle cell disease (SCD), its reported use has remained low in Africa and Nigeria where the largest number of SCD patients reside. Availability, cost, and concerns about safety and efficacy are some of the challenges to its use. Objectives: This study highlights the experience of using HU for children with sickle cell anemia in Ahmadu Bello University Teaching Hospital, Zaria. Materials and Methods: A descriptive, retrospective observational study of children is presented. Demographic, clinical, and laboratory features of children on HU, the indications for therapy and adverse clinical events encountered were analyzed. Results: A total of 165 children were treated with HU over a 4-year period, their ages ranging between 0.9 and 17 years. A total of 85 (47.5%) had HU for >12 months, while 61 (34.1%) were on treatment
