How long must I take bisphosphonates for osteoporosis? Are they a lifelong commitment?
Answer From Ann Kearns, M.D., Ph.D.
Bisphosphonates, the most common type of osteoporosis medications, are typically taken for at least 3 to 5 years. After that, your doctor will consider your risk factors in determining whether you should continue to take these or other osteoporosis medications.
Examples of bisphosphonates include:
- Alendronate (Binosto, Fosamax)
- Ibandronate (Boniva)
- Risedronate (Actonel, Atelvia)
- Zoledronic acid (Reclast, Zometa)
These drugs help strengthen bones and prevent fractures. The most common sites for osteoporosis fractures are the wrist, hip and spine. A broken hip can result in a severe decline in quality of life and even increases the risk of death.
Rarely, bisphosphonates may cause:
- Osteonecrosis of the jaw. This bone disease features pain, swelling or infection in the jaw. This occurs most commonly after invasive dental procedures, such as tooth extractions.
- Thighbone fractures. Long-term bisphosphonate therapy has been linked to a rare type of thigh fracture. This injury, known as atypical femoral fracture, is similar to a stress fracture, causing pain that begins subtly and can gradually worsen. If not identified early on, a complete fracture of the thighbone can occur.
To reduce the risk of these rare complications, your doctor may recommend that you temporarily stop taking bisphosphonates after 3 to 5 years. This is sometimes called a bisphosphonate holiday. People who have severe osteoporosis may need to wait for 10 years before they stop taking these drugs.
A bisphosphonate holiday typically lasts at least a year, but it may last indefinitely for some people if the risks of treatment outweigh the benefits. Luckily, the bone-strengthening effects of bisphosphonates appear to continue for several years after people stop taking the drugs.
