Teriparatide 250mcg/ml is a synthetic form of parathyroid hormone used to treat osteoporosis in postmenopausal women and men at high risk of fractures, as well as in cases of glucocorticoid-induced osteoporosis. It comes as a clear, colorless solution in a single-patient-use prefilled pen containing 600mcg/2.4ml, delivering daily subcutaneous injections typically in the thigh or abdomen. This formulation stimulates bone formation by mimicking the body's natural parathyroid hormone, thereby increasing bone mass and reducing fracture risk in the spine and other areas.
