Calcitonin: Uses, Side Effects

Calcitonin is a man-made form of a hormone that occurs naturally in the thyroid gland.

Calcitonin injection is used to treat Paget’s disease of bone, or high levels of calcium in the blood (hypercalcemia). Calcitonin injection is also used to treat osteoporosis in postmenopausal women.

Tell your doctor if you have ever had low levels of calcium in your blood (hypocalcemia).

It may not be safe to breast-feed a baby while you are using this medicine. Ask your doctor about any risks.

Side Effects

You may have increased bone pain during the first few months of treatment with calcitonin injection. This is not a sign that the medication isn’t working properly.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • a light-headed feeling, like you might pass out; or
  • low calcium levels–muscle spasms or contractions, numbness or tingly feeling (around your mouth, or in your fingers and toes).

Common side effects may include:

  • flushing (warmth, redness, or tingly feeling);
  • nausea, vomiting; or
  • swelling where the injection was given.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.

Calcitonin Interactions

Avoid driving or hazardous activity until you know how this medicine will affect you. Your reactions could be impaired.

If you have osteoporosis, avoid smoking, or try to quit. Smoking can reduce your bone mineral density, making fractures more likely.

Other drugs may affect calcitonin, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
