Calcitonin is a prescription medicine that is used for treating several conditions, including high blood calcium, Paget's disease, and osteoporosis. It is a manufactured version of a naturally occurring hormone that helps regulate bone formation and breakdown. Calcitonin comes in nasal spray and injectable form. Potential side effects of the drug include runny or stuffy nose, vomiting, and flushing.
As with any medicine, side effects are possible with calcitonin. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious side effects are less common.
Common side effects of calcitonin nasal spray include but are not limited to:
Runny or stuffy nose
Other nasal symptoms (such as nasal crusting, dryness, redness, and irritation)
