Teriparatide Overview

Updated: 

Teriparatide is a prescription medication used to treat both men and postmenopausal women with osteoporosis who are at high risk for having broken bones. Teriparatide is a synthetic hormone that is similar to the one the body makes naturally (parathyroid hormone). It works by causing the body to build new bone and increase bone strength by regulating calcium and phosphate.

Teriparatide comes in an injectable form that is given once daily. It is injected just under the skin of the stomach area or thigh.

Common side effects include nausea, joint aches, and pain.

Teriparatide and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Teriparatide and Lactation

Tell your doctor if you are breastfeeding or planning to breastfeed. It is not known if teriparatide is excreted in human breast milk or if it will harm your nursing baby.

Teriparatide Usage

  • Inject teriparatide one time each day in your thigh or abdomen (lower stomach area). Talk to a healthcare provider about how to rotate injection sites.

  • You can take teriparatide with or without food or drink.
  • The teriparatide delivery device has enough medicine for 28 days. It is set to give a 20 microgram dose of medicine each day. Do not inject all the medicine in the teriparatide delivery device at any one time.
  • Do not transfer the medicine from the teriparatide delivery device to a syringe. This can result in taking the wrong dose of teriparatide. If you do not have pen needles to use with your teriparatide delivery device, talk with your healthcare provider.
  • Teriparatide should look clear and colorless. Do not use teriparatide if it has particles in it, or if it is cloudy or colored.

  • After each use, safely remove the needle, recap the delivery device, and put it back in the refrigerator right away.
  • You can take teriparatide at any time of the day. To help you remember to take teriparatide, take it at about the same time each day.
  • If you forget or can not take teriparatide at your usual time, take it as soon as you can on that day. Do not take more than one injection in the same day.
  • If you take more teriparatide than prescribed, call your healthcare provider. If you take too much teriparatide, you may have nausea, vomiting, weakness or dizziness.
  • Follow your healthcare provider's instructions about other ways you can help your osteoporosis, such as exercise, diet, and reducing or stopping your use of tobacco and alcohol. If your healthcare provider recommends calcium and vitamin D supplements, you can take them at the same time you take teriparatide.

Teriparatide FDA Warning

WARNING: POTENTIAL RISK OF OSTEOSARCOMA

In male and female rats, teriparatide caused an increase in the incidence of osteosarcoma (a malignant bone tumor) that was dependent on dose and treatment duration. The effect was observed at systemic exposures to teriparatide ranging from 3 to 60 times the exposure in humans given a 20-mcg dose. Because of the uncertain relevance of the rat osteosarcoma finding to humans, prescribe teriparatide only for patients for whom the potential benefits are considered to outweigh the potential risk. Teriparatide should not be prescribed for patients who are at increased baseline risk for osteosarcoma (including those with Paget's disease of bone or unexplained elevations of alkaline phosphatase, pediatric and young adult patients with open epiphyses, or prior external beam or implant radiation therapy involving the skeleton) [see Warnings and Precautions, Adverse Reactions, and Nonclinical Toxicology.
