Anagrelide is a platelet reducing agent indicated for the treatment of thrombocythemia, secondary to myeloproliferative neoplasms, to reduce the elevated platelet count and the risk of thrombosis and to ameliorate associated symptoms including thrombo-hemorrhagic events. ( 1 ) Anagrelide capsules are indicated for the treatment of patients with thrombocythemia, secondary to myeloproliferative neoplasms, to reduce the elevated platelet count and the risk of thrombosis and to ameliorate associated symptoms including thrombo-hemorrhagic events .

Cardiovascular Toxicity: QT prolongation and ventricular tachycardia have been reported with anagrelide. Obtain a pre-treatment cardiovascular examination including an ECG in all patients. Monitor patients for cardiovascular effects. ( 5.1 ) Pulmonary Hypertension: Assess underlying cardiopulmonary disease prior to initiating therapy. ( 5.2 ) Bleeding Risk: Monitor patients for bleeding, including those receiving concomitant therapy with other drugs known to cause bleeding. ( 5.3 ) 5.1 Cardiovascular Toxicity Torsades de pointes and ventricular tachycardia have been reported with anagrelide. Obtain a pre-treatment cardiovascular examination including an ECG in all patients. During treatment with anagrelide monitor patients for cardiovascular effects and evaluate as necessary. Anagrelide increases the QTc interval of the electrocardiogram and increases the heart rate in healthy volunteers [ see Clinical Pharmacology ( 12.2 )]. Do not use anagrelide in patients with known risk factors for QT interval prolongation, such as congenital long QT syndrome, a known history of acquired QTc prolongation, medicinal products that can prolong QTc interval and hypokalemia [see Drug Interactions ( 7.1 )]. Hepatic impairment increases anagrelide exposure and could increase the risk of QTc prolongation. Monitor patients with hepatic impairment for QTc prolongation and other cardiovascular adverse reactions. The potential risks and benefits of anagrelide therapy in a patient with mild and …

Lactation: Advise not to breastfeed. ( 8.2 ) . 8.1 Pregnancy Risk Summary Available data from case reports with anagrelide use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal embryo-fetal studies, delayed fetal development (delayed skeletal ossification and reduced body weight) was observed in rats administered anagrelide hydrochloride during organogenesis at doses approximately 97 times the maximum clinical dose (10 mg/day) based on body surface area ( see Data ). There are adverse effects on maternal and fetal outcomes associated with thrombocythemia in pregnancy ( see Clinical …
