What Experts Say

Teriparatide is a genuine bone-building agent, unlike most osteoporosis treatments that only slow further bone loss without adding new bone. Given as a small daily pulse, it stimulates osteoblast activity and new bone formation rather than simply blocking the cells that break bone down, which sets it apart from bisphosphonates and denosumab.

Specialists typically reserve it for patients with severe osteoporosis, an existing history of fragility fractures, or those who have not responded adequately to standard bisphosphonate therapy over an extended period. Bone density scans before and during treatment help confirm the expected gains.

Because of its cost and injectable daily format, treatment courses are usually time-limited to a set duration set by the prescribing specialist, and are often followed by a bisphosphonate to help maintain the bone density gains achieved during the injectable phase. Calcium and vitamin D levels are checked before starting therapy.

Drug Interactions

• Digoxin: Raised calcium levels from this injection may increase the risk of digoxin toxicity.
• Other Osteoporosis Medicines: Combining with bisphosphonates may reduce the bone-building effect, so timing is usually staggered.

Risks and warnings

• Bone Tumor Risk: Carries a warning about a rare bone cancer seen in animal studies, so it is avoided in people with certain bone conditions or prior bone radiation.
