Sensipar Warnings/Precautions

Warnings/Precautions

Hypocalcemia: may increase risk of QT prolongation and ventricular arrhythmias in congenital or family history of long QT syndrome or sudden cardiac death, history of QT prolongation and other predispositions; monitor closely. Seizure disorders. If corrected serum calcium is below lower limit of normal or symptoms of hypocalcemia occurs, initiate or increase calcium supplementation. Monitor for adynamic bone disease; if iPTH levels decrease to <150pg/mL, reduce dose (Vit.D sterols and/or cinacalcet) or discontinue. Known gastritis, esophagitis, ulcers, severe vomiting: monitor for worsening GI reactions, bleeding, and ulcerations. Impaired cardiac function. Moderate and severe hepatic impairment. Pregnancy.

Secondary hyperparathyroidism in patients with chronic kidney disease on dialysis.

Swallow whole; take with food. Individualize. Initially 30mg once daily. Measure serum calcium and serum phosphorus within 1 week and iPTH within 1–4 weeks after start initiation or dose adjustment. Titrate dose every 2–4 weeks through sequential doses of 30mg, 60mg, 90mg, 120mg, and 180mg once daily until target iPTH levels of 150–300pg/mL. Assess serum iPTH levels no earlier than 12hrs after most recent dose. May take with Vit.D sterols and/or phosphate binders. Switching from etelcalcetide: discontinue etelcalcetide for ≥4 weeks before starting cinacalcet. Monitoring and dose adjustment: see full labeling.
