Calcitonin for Paget's disease of bone
|Generic Name||Brand Name|
Calcitonin is available for injection either under the skin (subcutaneous or subQ injection) or into the muscle (intramuscular or IM injection). Miacalcin is available in a nasal spray, but it is not approved by the U.S. Food and Drug Administration (FDA) for the treatment of Paget's disease.
How It Works
Calcitonin slows bone breakdown and rebuilding. It is injected under the skin for the treatment of Paget's disease.
Why It Is Used
People use calcitonin to control symptoms of Paget's disease and to slow the process of bone tissue breaking down and rebuilding too quickly. Doctors also may prescribe it to help prevent complications in people with Paget's disease who do not yet have symptoms.
How Well It Works
Calcitonin helps manage bone pain1.
Calcitonin may prevent future hearing loss, but it will not repair hearing loss that has already occurred.
The benefits of calcitonin may take many weeks to notice, and they often go away soon after the person stops taking the medicine. Calcitonin does not slow or eliminate disease activity as well as bisphosphonates do.2
You may feel sick to your stomach (nausea) after you receive a shot of calcitonin. But nausea usually gets better over time. Less common side effects of calcitonin include:
- Suddenly feeling very hot (flushed).
- Abdominal pain.
Taking the medicine in the evening after dinner can reduce side effects.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
You must take the injection form of calcitonin daily or at least several times a week. You or a family member can usually learn how to give the shot properly. It is important not to give the shot in the same place twice in a row. Changing places where the shots are given prevents damage to muscle tissue.
Some people develop a resistance to calcitonin. The medicine then stops working, and the disease becomes active again. Bisphosphonates appear to keep Paget's disease in an inactive state longer than calcitonin does.
The effects of calcitonin go away within a few months after you stop taking the medicine.
Miacalcin is available in a nasal spray. But this form has not been well-tested for Paget's disease.
