Cinacalcet: Uses & Sides Effects

Cinacalcet decreases levels of parathyroid hormone (PTH), calcium, and phosphorous in the body. Cinacalcet is used to treat hyperparathyroidism (overactive functioning of the parathyroid glands) in people who are on long-term dialysis for kidney disease. Cinacalcet is also used to treat hypercalcemia (high levels of calcium in the blood) in people with cancer of the parathyroid gland, and in people with overactive parathyroid glands that cannot be treated surgically.

How should I take cinacalcet?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use cinacalcet in larger or smaller amounts or for longer than recommended.

Cinacalcet works best if you take it with food or shortly after eating a meal.

Do not crush or break a cinacalcet tablet. Swallow the pill whole.

To be sure your calcium and phosphorous levels do not get too low, your blood will need to be tested 1 week after you start taking cinacalcet or whenever your dose is changed. You may also need blood tests on a regular basis during treatment.

Store at room temperature away from moisture, light, and heat.
