How should I use this medicine?

Teriparatide is administered as a 20 mcg daily subcutaneous injection via a prefilled pen, with supplemental calcium/vitamin D as needed.  

Dosage and Administration  

The standard dose is 20 mcg once daily via subcutaneous injection into the thigh or abdomen. Patients should receive calcium (1,000 mg/day) and vitamin D (≥400–800 IU/day) if dietary intake is insufficient. The prefilled pen delivers 28 doses; discard 28 days after first use. Initial doses should be given in a seated/lying position to mitigate orthostatic hypotension. Treatment duration is typically ≤2 years, extended only if fracture risk remains elevated. Avoid intravenous/intramuscular use. Storage requires refrigeration (2–8°C); freezing or prolonged room-temperature exposure invalidates the product.
