Miacalcin (calcitonin) is a man-made form of a hormone that occurs naturally in the thyroid gland.

Miacalcin nasal spray is used to treat osteoporosis in women who have been in menopause for at least 5 years. It should be used along with adequate calcium and vitamin D intake.

Miacalcin nasal spray should be reserved for patients for whom alternative treatments are not suitable e.g. patients where other therapies are not suitable or for patients who are intolerant or unwilling to use other treatments.
