PRESCRIBED FOR: Teriparatide is a prescription medicine that is used to treat (1) postmenopausal women with osteoporosis who are at high risk for bone fractures, (2) men with primary or hypogonadal osteoporosis at high risk for fractures, and (3) men and women with osteoporosis due to the use of steroid medicines who are at high risk for fractures.

SIDE EFFECTS: The most common side effects of teriparatide are

Teriparatide can cause some serious side effects including a drop in blood pressure when getting up from a sitting or lying position (orthostatic hypotension) and increased calcium in the blood.

In animal studies some rats developed osteosarcoma, a type of bone cancer. Osteosarcoma is a rare but serious form of cancer rarely reported in patients taking teriparatide. To investigate if teriparatide increases the risk of osteosarcoma, a voluntary patient registry has been developed. Patients can get more information about this registry by calling 1-866-382-6813 or visiting www.forteoregistry.rti.org.


  • Patients with Paget's disease of bone, pediatric and young adult patients with open epiphyses (ends of long bones that are still growing), and patients with prior external beam or implant radiation involving the skeleton should not receive teriparatide.
  • Teriparatide should not be used for more than 2 years in a patient's lifetime and should not be given to patients with bone cancer, history of skeletal cancer, metabolic bone diseases other than osteoporosis, or hypercalcemic disorders.
  • Teriparatide may increase blood levels of calcium and uric acid. It may also increase calcium levels in urine.
