About Hydroxyurea
Hydroxyurea (also called hydroxycarbamide) is the single most important medicine for sickle cell disease — and that matters enormously in Nigeria, which has the largest sickle cell population in the world, with tens of thousands of affected babies born every year. It is a daily capsule or tablet that changes the course of the disease, reducing the frequency of painful crises, cutting the need for blood transfusions, and lowering the risk of serious complications. It is sold as Hydrea, Siklos, and generic hydroxyurea.
