Cinacalcet Normon acts by controlling the levels of parathyroid hormone (PTH), calcium, and phosphorus in your body, and is used to treat alterations of the parathyroid glands. The parathyroid glands are four small glands located in the neck, near the thyroid gland, that produce parathyroid hormone (PTH).

Cinacalcet Normon is used in adults:

• to treat secondary hyperparathyroidism in adults with severe kidney disease who require dialysis to remove waste products from their blood.
• to reduce high levels of calcium in the blood (hypercalcemia) in adult patients with parathyroid cancer.
• to reduce high levels of calcium in the blood (hypercalcemia) in adult patients with primary hyperparathyroidism when removal of the parathyroid glands is not possible.

Cinacalcet Normon is used in children between 3 years and less than 18 years:

• to treat secondary hyperparathyroidism in patients with severe kidney disease who require dialysis to remove waste products from their blood, and whose condition is not controlled with other treatments.

In primary and secondary hyperparathyroidism, the parathyroid glands produce too much PTH. The term “primary” means that the hyperparathyroidism is not caused by any other disease and “secondary” means that the hyperparathyroidism is caused by another disease, such as kidney disease. Both primary and secondary hyperparathyroidism can cause loss of calcium from the bones, which can produce bone pain and fractures, problems in blood vessels and heart vessels, kidney stones, mental disease, and coma.

Do not take Cinacalcet Normonif you are allergic to cinacalcet or any of the other ingredients of this medication (listed in section 6).

Do not take Cinacalcet Normonif you have low levels of calcium in your blood. Your doctor will monitor your calcium levels in the blood.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take cinacalcet.

Before starting to take cinacalcet, inform your doctor if you have ever suffered from:

• seizures(attacks or crises). The risk of seizures is higher in people who have had them before;
• liver problems;
• heart failure.

Cinacalcet reduces calcium levels. In adults and children treated with cinacalcet, life-threatening events and fatal outcomes associated with low calcium levels (hypocalcemia) have been reported.

Inform your doctor if you experience any of the following symptoms that may indicate low calcium levels: muscle spasms, contractions, or cramps, or numbness or tingling in the fingers of the hands, feet, or around the mouth, or seizures, confusion, or loss of consciousness while taking cinacalcet.

Low calcium levels can affect your heart rhythm. Inform your doctor if you experience abnormally strong or rapid heartbeats, if you have problems with your heart rhythm, or if you take medications that can cause heart rhythm problems while taking cinacalcet.

For additional information, see section 4.
