What is teriparatide?

  • Teriparatide is used to treat severe osteoporosis (bone loss), in people who have a high chance of getting fractures. 
  • It lessens the risk of a broken bone or fracture. 
  • Teriparatide is a man-made form of a natural hormone in the body called parathyroid hormone, which is important for maintaining healthy bones. Teriparatide increases bone formation, thereby increasing bone strength and reducing the chance of fracture.
  • Teriparatide is available as an injection.

Dose

  • The dose of teriparatide is 20 micrograms injected once daily usually for up to 18 months.
  • Always take your teriparatide exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much teriparatide to take, how often to take it, and any special instructions.

How to take teriparatide

  • Inject teriparatide under the skin (subcutaneously), in the thigh or in the tummy area (abdomen). 
  • Teriparatide comes in a pen-shaped device to make the daily injection easier. The pen injector contains enough medicine for 28 doses.
  • Use a new needle for each injection.
  • Throw away the pen after 28 days of use, even if it is not empty.
  • Try to administer your injection around the same time every day to help you remember. The best time to take it is at night before going to bed.
  • If you forget your dose, inject it as soon as you remember that day. But, if it is nearly time for your next dose, just inject the next dose at the right time. Do not inject more than one dose per day.
  • Your doctor will usually recommend that you take calcium and vitamin D as additional treatment for osteoporosis.

Like all medicines, teriparatide can cause unwanted side effects, although not everyone gets them. Often unwanted side effects improve as your body gets used to the new medicine.
