What is anagrelide (Agrylin)?

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 other purposes not listed in this medication guide.
