How does this medication work? What will it do for me?
Calcitonin is a medication that is also known as a calcium regulator. It is used to treat hypercalcemia (too much calcium in the blood) by working in the kidney to remove the calcium from the body. Calcitonin also works by slowing down the rate of bone breakdown.
Calcitonin is also used to treat symptoms of Paget's disease when other treatments have not been successful. Paget’s disease causes inflammation of the bones, in turn causing pain and changes to the breakdown and formation of bones. Calcitonin is used by itself or in combination with other medications when it is necessary to quickly remove excess amounts of calcium from the blood.

This should be done by a nurse or doctor in the hospital. Depending on the reduction in calcium in the body, your doctor may increase this dose to a maximum of 8 IU per kilogram of body weight, injected 4 times a day.
