Parathyroid hormone has been shown to increase the rate of bone tumors in lab animals. It is not known if there is a higher risk of bone tumors in humans. Parathyroid hormone is only for use in people not controlled on calcium and vitamin D treatment. Parathyroid hormone is also only for use when the benefits are thought to be more than the risks.
Parathyroid hormone should not be used in patients who are at risk for bone tumors, including children and young adults whose bones have not finished growing, and patients with Paget disease, prior radiation involving the skeleton, or unexplained high levels of alkaline phosphatase in their blood.
You can only get parathyroid hormone through the Natpara REMS Program.
