Does forteo work?

Does Forteo actually work for osteoporosis?

Forteo (teriparatide) increases bone density by mimicking parathyroid hormone. It stimulates new bone formation rather than just slowing breakdown. Clinical studies show it raises bone mineral density at the spine and hip, and reduces vertebral fracture risk by up to 65 percent in postmenopausal women.

What results do patients report seeing?

Many patients gain noticeable bone density improvements after 18–24 months of daily injections. Real-world data indicate 2–10 percent gains at the spine and 2–4 percent at the hip. Some people feel less back pain once bone strength improves. Some patients do not respond well, with zero or minimal gain.

How does Forteo compare to other osteoporosis drugs?

Forteo works faster than bisphosphonates such as alendronate. It builds bone rather than merely preserving it. The drug remains active for a lifetime after treatment ends. Lifetime fracture risk reduction continues beyond the two-year limit. Lifetime fracture risk reduction continues beyond the two-year limit.
