Serious Adverse Events

Orthostatic hypotension with teriparatide therapy

Teriparatide may cause transient orthostatic hypotension (Forteo Package Insert, 2012).

  • Typically, an event began within 4 hours of dosing and spontaneously resolved within a few minutes to a few hours

Teriparatide should be administered initially under circumstances in which the patient can sit or lie down if symptoms of orthostatic hypotension occur (Forteo Package Insert, 2012).

Serum calcium elevation with teriparatide therapy

Teriparatide may cause slight and transient increase in serum calcium (Forteo Package Insert, 2012).

  • Maximum concentrations are reached between 4 and 6 hours and return to baseline by 16 to 24 hours

Therefore, if blood samples for serum calcium are taken, it should be done at least 16 hours after the most recent teriparatide injection (Forteo Package Insert, 2012).
