WHY is this medicine prescribed?

Cinacalcet is used alone or with other medications to treat secondary hyperparathyroidism (a condition in which the body produces too much parathyroid hormone [a natural substance needed to control the amount of calcium in the blood] which can cause serious problems with the bones, heart, blood vessels, and lungs) in patients with chronic kidney disease (condition in which the kidneys stop working slowly and gradually) who are being treated with dialysis (medical treatment to clean the blood when the kidneys are not working properly). Cinacalcet is also used to treat high levels of calcium in the blood of patients who have parathyroid cancer (cancer of the glands in the neck that make parathyroid hormone). Cinacalcet is in a class of medications called calcimimetics. It works by signaling the body to produce less parathyroid hormone in order to decrease the amount of calcium in the blood.

HOW should this medicine be used?

Cinacalcet comes as a tablet to take by mouth. It is usually taken once a day with food or shortly after a meal. To help you remember to take cinacalcet, take it at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take cinacalcet exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them.

Your doctor will probably start you on a low dose of cinacalcet and gradually increase your dose, not more than once every 2-4 weeks.

Cinacalcet may help control your condition but will not cure it. Continue to take cinacalcet even if you feel well. Do not stop taking cinacalcet without talking to your doctor.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.http://www.upandaway.org
