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 times to 60 times the exposure in humans given a 20 mcg dose. Because of the uncertain relevance of the rat osteosarcoma finding to humans, teriparatide should be prescribed only to 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, open epiphyses, or prior external beam or implant radiation therapy involving the skeleton) .

Teriparatide is a synthetic form of the natural human parathyroid hormone and is used by injection to treat osteoporosis. Teriparatide forms new bone, increases bone mineral density and bone strength, and as a result reduces the chance of getting a fracture (broken bone). Teriparatide can be used by men or postmenopausal women with osteoporosis who are at high risk for having fractures. Teriparatide can be used by people who have had a fracture related to osteoporosis, or who have multiple risk factors for fracture, or who cannot use other osteoporosis treatments.
Teriparatide has been used by injection into a vein as a test to help diagnose problems of the parathyroid gland. This test determines whether you have hypoparathyroidism or a type of pseudohypoparathyroidism.
This product, for use as a test to help diagnose problems of the parathyroid gland, was withdrawn from the U.S. market in January 1997.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For teriparatide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to teriparatide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of teriparatide in the pediatric population. Safety and efficacy have not been established. Use in children or young adults is not recommended due to possible effects on growing bones .
Appropriate studies performed to date have not demonstrated geriatrics-specific problems that would limit the usefulness of teriparatide in the elderly .
|All Trimesters||C||Animal studies have shown an adverse effect and there are no adequate studies in pregnant women OR no animal studies have been conducted and there are no adequate studies in pregnant women.|
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
