Calcitonin and Osteoporosis

Calcitonin is a hormone found naturally in our bodies. It is made by the thyroid gland and controls the activity of the osteoclasts (bone-eroding cells). A synthetic form of calcitonin (Miacalcin*NS®) is used in a nasal spray.

How does calcitonin work?

Calcitonin slows down the work of the osteoclasts. This allows the osteoblasts (bone-building cells) to work more effectively.

How effective is it?

Nasal calcitonin maintains or minimally increases bone density and prevents fractures of the spine. It also reduces the pain associated with vertebral fractures.

Who can take it?

Nasal calcitonin is used to treat osteoporosis in postmenopausal women. It can also be used to treat osteoporosis in non-pregnant premenopausal women and men. It is not used to prevent osteoporosis.

How is it taken?

The daily dosage is one spray (200 IU) in one nostril, alternating nostrils each day.

Are there side effects?

Side effects can include nasal dryness and swelling of the nasal membranes.
