Parathyroid hormones are used to treat osteoporosis and manage hypoparathyroidism. These medications work to treat osteoporosis by stimulating bone formation. And they help manage complications of hypoparathyroidism by increasing the calcium levels in the blood. Parathyroid hormones are typically available as injectables. Examples include Forteo (teriparatide), Tymlos (abaloparatide), and Natpara (parathyroid hormone). You can discuss with your prescriber about which option is best for you.
