What Calcitonin is and what it is used for
Calcitonin contains the active substance calcitonin (salmon, synthetic).
Calcitonin is a hormone that occurs naturally in the body of both humans and animals. It
regulates the level of calcium in the blood. Calcitonin is used to reverse bone loss and may
also help in bone formation.
Calcitonin can be given for the following conditions:
- Prevention of bone loss in patients who have suddenly become immobile. For example,
patients who are bed-bound because of a fracture.
- Paget’s disease of bone in patients who cannot take other treatments for this condition, for
example patients with serious kidney problems. Paget’s disease is a slowly progressing
illness which can cause a change in the size and shape of certain bones.
- Treatment of high calcium levels in the blood (hypercalcemia) due to cancer.
What you need to know before you take Calcitonin
Do not take Calcitonin
if you are allergic to calcitonin (salmon, synthetic) or any of the other ingredients of this
medicine (listed in section 6);
if you have a very low calcium level in your blood (hypocalcaemia).
Warning and precautions
Before treatment with Calcitonin tell your doctor if you suspect to be allergic to calcitonin
(salmon, synthetic). Your doctor will perform a skin test before you start taking Calcitonin.
Please tell your doctor if you have been diagnosed with cancer. In clinical trials, patients
treated with calcitonin for osteoporosis and osteoarthritis have shown an increase in the risk
of cancer following long term treatment. Your doctor will decide if calcitonin is a suitable
treatment for you and for how long you can be treated.
Children and adolescent (age under 18 years)
Use of Calcitonin is not recommended in patients under 18 years of age.
Calcitonin can be used by older people without any specific requirements.
Other medicines and Calcitonin

It is particularly important to tell your doctor if you are taking medicines:
used to treat heart problems (e.g. digoxin) or high blood pressure (e.g. amlodipine,
containing lithium, as the dose of lithium may need to be changed;
containing bisphosphonate (used to treat osteoporosis).
Pregnancy, breast-feeding and fertility
Calcitonin should not be used by pregnant women. If you are breast-feeding use of Calcitonin
is not recommended.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a
baby, ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
Calcitonin may cause tiredness, dizziness and disturbed vision which could impair your
reactions. If this happens to you, do not drive or use any machines.

How to take Calcitonin
Always take this medicine exactly as your doctor has told you. Check with your doctor, nurse
or pharmacist if you are not sure. It is advisable to administer the medication at bedtime in
order to reduce the occurrence of nausea (feeling sick) or vomiting (being sick) which may
occur especially at the beginning of the therapy.
Do not exceed the recommended dosage. Do not take Calcitonin if you notice that the
solution is not clear and colourless. Do not change the dose or stop treatment without first
talking to your doctor.
Calcitonin is usually given by injection either into the tissue just under the skin (subcutaneous
injection) or into a muscle (intramuscular injection). Occasionally, the injection is given by a
slow infusion into a vein (slow intravenous infusion).
If you will be giving yourself subcutaneous injections, make sure you understand exactly how
to prepare and give them. Your doctor or nurse will give you precise instructions. Do not
inject yourself unless you are confident of your ability to do so.
You should not use the injection or infusion straight from the fridge. Let it reach room
temperature naturally first. The ampoules should be used immediately after opening. Excess
amount of Calcitonin should be discharged.
Your doctor will decide the correct dose and how long you should receive calcitonin
treatment depending on your condition.
The usual doses are:
For prevention of bone loss: 100 IU per day or 50 IU twice daily for 2 to 4 weeks, given
into the muscle or the tissue just under the skin.
For Paget’s disease: 100 IU daily injected into a muscle or into the tissue just under the
skin, normally for up to 3 months. In some cases, your doctor might decide to extend your
treatment up to 6 months.
For the treatment of high calcium levels: 100 IU every 6 to 8 hours, given into a
muscle or into the tissue just under the skin. In some cases, it may be given by injection
into a vein.
If you inject more Calcitonin than you should
If you accidentally inject too much Calcitonin, contact your doctor immediately. You may
require medical attention.
If you forget to inject Calcitonin
If you forget to inject yourself a dose, give it as soon as you remember it unless it is less than
4 hours until your next dose is due. In that case, wait and inject your next dose at the usual
time. Do not inject a double dose to make up for a forgotten one.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
