Hydroxyurea (also known as hydroxycarbamide) is prescribed for a number of different conditions. There are three brands of the medicine available. The brand of hydroxyurea capsules called Hydrea® is prescribed for people with some types of cancer, and also for people with a condition known as polycythemia rubra vera. The brands of hydroxyurea capsules called Droxia® and Siklos® are prescribed for people with sickle cell disease. It is important that each time you collect a new supply of medicine, you make sure it is the same brand of hydroxyurea that you have had before.
