The recommended starting dose of calcitonin for treating Paget's disease is 100 IU (international units) once daily, given by subcutaneous (under the skin) or intramuscular (into a muscle) injection.

Calcitonin is used with the guidance and supervision of a doctor. Your doctor or nurse may ask you to inject the medication at home once they have instructed you and are certain that you won't have any problems with doing it at home. Do not attempt to prepare or inject Apo Calcitonin on your own until you completely understand how to prepare and inject a dose.

When used to treat hypercalcemia, the dose of calcitonin is based on body weight (4 IU per kilogram of body weight) and injected every 12 hours by subcutaneous or intramuscular injection. This should be done by a nurse or doctor in the hospital. Depending on the reduction in calcium in the body, your doctor may increase this dose to a maximum of 8 IU per kilogram of body weight, injected 4 times a day.

Calcitonin should be used for the shortest time possible.

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 ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to use Apo Calcitonin exactly as prescribed by your doctor. If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not inject a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Apo Calcitonin in the refrigerator between 2°C to 8°C. Protect it from light and moisture, and keep it out of the reach of children.

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.
