Miacalcin Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Miacalcin (calcitonin-salmon) is used to treat Paget's disease of bone, postmenopausal osteoporosis, or high levels of calcium in the blood (hypercalcemia). It is a man-made form of a hormone that occurs naturally in the thyroid gland. Common side effects include runny nose, nose bleeds, nasal irritation, dry nose with crusting, headache, dizziness, nausea, flushing of the face, or back pain.

The recommended dose of Miacalcin Nasal Spray in postmenopausal osteoporotic females is one spray (200 I.U.) per day administered intranasally (in the nose), alternating nostrils daily. There may be other drugs that can affect Miacalcin. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor. Miacalcin is used mainly in women after menopause. It is unlikely to be used during pregnancy or breast-feeding. Consult your doctor if you have any questions about this product and pregnancy or breast-feeding.

Common adverse reactions associated with the use of injectable calcitonin-salmon occurred less frequently in patients treated with Miacalcin (calcitonin-salmon) Nasal Spray than in those patients treated with injectable calcitonin. Nausea, with or without vomiting, which occurred in 1.8% of patients treated with the nasal spray (and 1.5% of those receiving placebo nasal spray) occurs in about 10% of patients who take injectable calcitonin-salmon. Flushing, which occurred in less than 1% of patients treated with the nasal spray, occurs in 2%-5% of patients treated with injectable calcitonin-salmon. Although the administered dosages of injectable and nasal spray calcitonin-salmon are comparable (50-100 units daily of injectable versus 200 units daily of nasal spray), the nasal dosage form has a mean bioavailability of about 3% (range 0.3%-30.6%) and therefore provides less drug to the systemic circulation, possibly accounting for the decrease in frequency of adverse reactions.

The collective foreign marketing experience with Miacalcin (calcitonin-salmon) Nasal Spray does not show evidence of any notable difference in the incidence profile of reported adverse reactions when compared with that seen in the clinical trials.
