Cinacalcet is used to treat increased amounts of a certain hormone (parathyroid) in people with long-term kidney disease who are on dialysis.

Cinacalcet works by decreasing the amount of parathyroid hormone, calcium, and phosphorus in your body. Having the right amount of these substances in your body helps to prevent bone disease.
