We want to alert you to the recall of all doses of Natpara (parathyroid hormone) on Sept. 6, 2019.1 We recommend you review your medical records and contact all patients for whom you have prescribed Natpara to warn them of the recall to ensure safe discontinuation of the medication. We would like to remind you that abrupt discontinuation of Natpara or dose interruption in patients can result in severe hypocalcemia as stipulated in the Natpara Full Prescribing Information.2

Due to removal of this drug from the market, we have listed an alternative option below. It is important to note that according to the prescribing information and the American Association of Clinical Endocrinologists, Natpara use is recommended only for patients who cannot be well-controlled on calcium supplements and active forms of vitamin D alone. Therefore, your patient(s) may have already tried or are currently taking this alternative.3

Takeda voluntarily recalled all doses of Natpara (25 mcg, 50 mcg, 75 mcg, 100 mcg). This recall was initiated due to a potential issue related to rubber particulates originating from the rubber septum of the Natpara cartridge. During the 14-day Natpara treatment period, the septum is punctured by a needle each day to obtain the daily dosage of medicine solution. When the septum is repeatedly punctured, it is possible that small rubber fragments may detach into the cartridge.1

This drug is used for the treatment of hypocalcemia in patients with hypoparathyroidism as an adjunct to calcium and vitamin D supplementation.2
