Why teriparatide is contraindicated in Paget’s disease?
Teriparatide has a box warning for osteosarcoma. Because of this, teriparatide should not be used in Paget’s disease, in pediatric or young adults with open epiphyses, or in subjects with a history of skeletal malignancies. Lifetime use for more than 2 years is not recommended.
How long should a patient be treated with teriparatide?
As a consequence, the approved lifetime duration of treatment with teriparatide is 24 months . Because teriparatide is approved in patients at high risk for fracture who are generally of increased clinical concern, the correct use of teriparatide may be important to achieve optimal outcomes.
Is Forteo a safe drug?
