Hydroxycarbamide is prescribed for a number of different conditions. There are multiple brands of the medicine available. The brand of hydroxycarbamide capsules called Hydrea® are prescribed for people with some types of cancer, and also for people with a condition known as polycythaemia rubra vera. The brand of hydroxycarbamide tablets called Siklos® is 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 hydroxycarbamide that you have had before.
