How it works
Hydroxycarbamide is one of a group of chemotherapy drugs known as anti metabolites. These drugs stop cells making and repairing DNA. Cancer cells need to make and repair DNA in order to grow and multiply.
How you have it
Hydroxycarbamide comes as 500mg capsules. Your doctor might ask you to take these in one dose or in several doses during the day.
Swallow your tablets whole with a glass of water. If you have difficulty swallowing capsules, you can empty the contents of the capsules into a glass of water. Then drink it all straight away. Don't leave any behind in the glass.
You usually have hydroxycarbamide as a course of several cycles of treatment. Sometimes there might be a break between cycles.
When you have hydroxycarbamide and how often depends on your type of cancer and your situation.
Taking your tablets or capsules
Whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, not more or less.
Never stop taking a cancer drug without talking to your specialist first.
Tests during treatment
You have blood tests before starting treatment and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.

Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.
