What Is Anagrelide

Anagrelide lowers the number of blood clotting cells (platelets) in the body, which helps prevent blood clots from forming.
Anagrelide is used to treat a condition called thrombocythemia (also called thrombocytosis). Thrombocythemia is a blood cell disorder in which too many platelet cells are produced, causing bleeding or blood-clotting problems.
Anagrelide may also be used for purposes not listed in this medication guide.
You should not use anagrelide if you have moderate to severe liver disease.

Anagrelide Interactions

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
Do not take aspirin unless your doctor has told you to. Follow your doctor's instructions about how much aspirin to take, and how often to take it.
Ask a doctor or pharmacist before using any other pain, cold, allergy, or sleep medication. Aspirin (sometimes abbreviated as ASA) is contained in many combination medicines. Although aspirin is sometimes prescribed for use with anagrelide, taking these medications together may increase your risk of bleeding. Check the label to see if a medicine contains aspirin or ASA.
Other drugs may interact with anagrelide, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
