Why is teriparatide limited to 2 years?

As stated above, the FDA black box warning limiting therapy duration to 2 years relates to the association of teriparatide with an increased risk of osteosarcoma in rat studies. This risk was related to both dose and duration of the medication.

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 [3]. 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?

The drug carries a “black box” safety warning, the FDA’s highest warning level, which highlights the concern over the association between Forteo and bone tumors (called osteosarcomas) in animal studies.

After teriparatide was stopped, BMD at the posterior-anterior spine decreased by 7.1 ± 3.8% in women and by 4.1 ± 3.5% in men (P = 0.036). BMD at the total hip and femoral neck decreased by 3.8 ± 3.9 and 3.1 ± 4.3%, respectively, in women but remained stable in men (P < 0.05 for both sites).

How quickly does teriparatide work?
