Forteo is quickly absorbed from the injection site, has a half-life of approximately 1 hour, and is undetectable in the blood within 3 hours


Forteo® (teriparatide [rDNA origin] injection) is rapidly and extensively absorbed following subcutaneous injection, with a Cmax at approximately 30 minutes (Forteo Package Insert, 2012; Satterwhite, 2010).

Systemic clearance of teriparatide is approximately 62 L/hr in women and 94 L/hr in men, which exceeds the rate of normal liver plasma flow, consistent with both hepatic and extra-hepatic clearance (Forteo Package Insert, 2012).
