Common Name:

calcitonin salmon nasal spray


How does this medication work? What will it do for me?

Calcitonin salmon nasal spray belongs to the group of medications called bone metabolism regulators. It is used to treat osteoporosis for women who are more than 5 years past menopause.

Calcitonin is a hormone that occurs naturally in the human body. Calcitonin salmon is similar to human calcitonin hormone in many ways, but is longer-acting and more potent than human calcitonin. Calcitonin salmon is not derived from salmon, but is a man-made version of calcitonin produced by salmon. Calcitonin salmon nasal spray works by reducing the rate of bone breakdown caused by cells in the bone called osteoclasts and may encourage cells called osteoblasts to build up the bones. This increases the density of bone in the lower spine.

Miacalcin® NS is no longer being manufactured for sale in Canada. For brands that may still be available, search under calcitonin salmon nasal spray. This article is being kept available for reference purposes only. If you are using this medication, speak with your doctor or pharmacist for information about your treatment options.

How should I use this medication?

The recommended dose of calcitonin salmon nasal spray is one spray (200 IU) in one nostril daily, alternating nostrils each day.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the one above, do not change the way that you are taking the medication without talking to your doctor.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

When starting a new bottle of nasal spray, allow the spray to reach room temperature and then prime the pump by pressing down firmly on the pump 3 times. When green is showing in the dose counter window, the new spray is ready to use.

Directions for use (refer to the package for detailed instructions):

  • Remove the protective cap.
  • Bend your head slightly forward and insert the applicator nozzle into one of your nostrils. Make sure the nozzle is placed in a straight line with your nasal passage to allow the spray mist to spread after taking a dose. Depress the plunger once and release.
  • After taking a dose, sniff several times to prevent the solution from dripping out of your nostril. Do not blow your nose immediately after taking a dose.

Be aware that the nasal spray contains 14 doses. You will know the 14 doses have been used when a red marker appears in the counter window.

Store new, unopened bottles in the refrigerator between 2°C and 8°C. Do not allow the spray to freeze, avoid shaking, and keep it out of the reach of children.

Once opened, keep the spray at room temperature and use within 4 weeks. Store and carry the bottle in an upright position to ensure the correct dose is measured each time.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
