Before Using This Medicine:


Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Studies on this medicine have been done only in adult patients, and there is no specific information comparing the use of calcitonin in children with use in other age groups. Therefore, be sure to discuss with your doctor the use of this medicine in children.

Older adults

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing the use of calcitonin in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults. Calcitonin is often used in elderly patients.


Calcitonin has not been studied in pregnant women. However, in animal studies, calcitonin has been shown to lower the birth weight of the baby when the mother was given a dose of calcitonin many times the human dose.


Calcitonin has not been reported to cause problems in nursing babies. However, studies in animals have shown that calcitonin may decrease the flow of breast milk.

Other medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Other interactions

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Proper Use of This Medicine:

Make certain your health care professional knows if your diet includes large amounts of calcium-containing foods and/or vitamin D-containing foods, such as milk or other dairy products. Calcium and vitamin D may cause the calcitonin to be less effective in treating a high blood calcium. Also let your health care professional know if you are on any special diet, such as low-sodium or low-sugar diet.

This medicine is for injection only. If you will be giving yourself the injections, make sure you understand exactly how to give them, including how to fill the syringe before injection. If you have any questions about this, check with your doctor.

Use the calcitonin only when the contents of the syringe are clear and colorless. Do not use it if it looks grainy or discolored.
