  • Tell your health care provider if you have ever had any heart problems including a long QT on an ECG.
  • Inform your health care professional if you are pregnant or may be pregnant prior to starting this treatment. Pregnancy category C (use in pregnancy only if benefit to mother outweighs risk to fetus).
  • For both men and women: Do not conceive a child (get pregnant) while taking anagrelide. Barrier methods of contraception, such as condoms, are recommended. Discuss with your doctor when you may safely become pregnant or conceive a child after therapy.
  • Do not breast feed while taking this medication.

Self-Care Tips:

  • You may feel drowsy and/or dizzy when you first start taking anagrelide. This should lessen as your body adjusts to the drug. Do not drive a car or operate machinery if you are feeling drowsy, dizzy or less alert than usual.
  • You may bleed more easily. Be careful and avoid injury. Use a soft toothbrush and an electric razor.
  • To reduce nausea, take anti-nausea medications as prescribed by your doctor, and eat small, frequent meals.
  • Drink at least two to three quarts of fluid every 24 hours, unless you are instructed otherwise.
  • In general, drinking alcoholic beverages should be minimized or avoided. You should discuss this with your doctor.
  • Get plenty of rest.
  • Maintain good nutrition.

Monitoring and Testing:

You will be monitored carefully and regularly by your doctor while you are taking anagrelide. Before beginning this therapy and during treatment, your cardiovascular (heart) health will be assessed. Blood tests and other monitoring will be done periodically throughout your treatment program to spot any side effects early on and to assess your response to the medicine.

How Anagrelide Works:

Thrombocythemia is a blood disorder in which there are too many platelets found in the blood. The megakaryocyte is the cell type from which platelets are produced. It is in the mature stage of the megakaryocyte's development that platelets are formed. If this maturation process is stopped platelets are unable to be produced.

Anagrelide interferes with the megakaryocyte maturation. It does this by blocking an enzyme (phospholipase A2) which is needed for completing the maturation process of megakaryocytes.
