What Sensipar is used for

Sensipar is used to treat:
a condition called secondary hyperparathyroidism (high-per-para-THIGH-royd-izm) in people with kidney disease who require dialysis treatment.
a condition called primary hyperparathyroidism when surgical removal of the parathyroid gland is not a treatment option.
high blood calcium levels in people with cancer of the parathyroid gland.
Secondary hyperparathyroidism
Kidney disease can cause a condition called secondary hyperparathyroidism, which can have a big impact on your health. Four small glands located behind the thyroid gland in your neck are called parathyroid glands. They make a hormone called parathyroid hormone (PTH). Normally, PTH makes sure you have just enough calcium and phosphorus in your blood to keep your bones, heart, muscles, nerves and blood vessels working well. When your kidneys are working properly, PTH keeps your calcium and phosphorus levels normal by moving the right amounts of calcium and phosphorus in and out of your bones.
When your kidneys aren't working properly, the calcium and phosphorus balance in your body is upset, and your parathyroid glands send out too much PTH to your body. This condition is called secondary hyperparathyroidism, and it can cause bone disease and also may be a risk factor for heart disease and abnormal calcium deposits in blood vessels and other parts of the body. Sensipar lowers PTH by telling your parathyroid glands to stop releasing too much PTH into your blood. It also lowers your calcium and phosphorus levels.
Primary hyperparathyroidism/ Cancer of the parathyroid gland
An overactive parathyroid gland results in a condition called primary hyperparathyroidism, which can impact your health. Four small glands located behind the thyroid gland in your neck are called parathyroid glands. They make a hormone called parathyroid hormone (PTH). When your parathyroid glands are working normally, PTH keeps your calcium levels normal by moving the right amounts of calcium in and out of your bones.
Primary hyperparathyoidism is caused by an enlargement of one or more of the parathyroid glands occasionally due to cancer of the parathyroid gland. In primary hyperparathyroidism, your parathyroid glands send out too much PTH to your body and your blood level of calcium becomes high. Sensipar lowers PTH by telling your parathyroid glands to stop releasing too much PTH into your blood. It also lowers your blood calcium levels.
Your doctor may have prescribed Sensipar for another reason. Ask your doctor if you have any questions about why Sensipar has been prescribed for you.
