About this medication
What the medication is used for:
SENSIPAR is used:
- to treat secondary hyperparathyroidism (high-per-pear-uh-THIGH-royd-izm) in patients with chronic kidney disease (CKD) receiving dialysis;
- to reduce high levels of calcium in the blood (hypercalcemia) in patients with parathyroid cancer;
- to reduce high levels of calcium in the blood (hypercalcemia) in patients with primary hyperparathyroidism when removal of the gland(s) is not possible.
What it does:
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, PTH keeps your calcium and phosphorus levels normal by moving the right amounts of calcium and phosphorus in and out of your bones. Chronic Kidney Disease (CKD) can cause a condition called secondary hyperparathyroidism.
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 can cause bone disease and also may be a risk factor for heart disease and abnormal calcification of blood vessels and other parts of the body. SENSIPAR treats secondary hyperparathyroidism by lowering PTH. This helps keep calcium and phosphorus within proper levels.
Parathyroid carcinoma/Primary hyperparathyroidism
Primary hyperparathyroidism is caused by an overactive, enlarged parathyroid gland (or 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. This helps lower your blood calcium levels.
When it should not be used:
You should not take SENSIPAR if you are hypersensitive (allergic) to any of the ingredients in the tablet.

Warnings and precautions
BEFORE you use SENSIPAR talk to your doctor or pharmacist if:
- You have or had seizures (convulsions). The risk of having a seizure is greater if you have had seizures before.
- You have or had heart problems (low blood pressure or worsening heart failure).
- You have or had liver problems.
- You have lower blood calcium levels.
- You are pregnant, breastfeeding, or plan to do so.
If you become pregnant while taking SENSIPAR, you are encouraged to enroll in Amgen’s Pregnancy Surveillance Program. If you choose to breastfeed while taking SENSIPAR, you are encouraged to enroll in Amgen’s Lactation Surveillance Program. You can enroll in these programs by calling 1-866-512-6436.
Low calcium levels can have an effect on your heart rhythm. Tell your doctor if you experience an unusually fast or pounding heart beat, if you have heart rhythm problems, or if you take medicines known to cause heart rhythm problems, while taking SENSIPAR.
SENSIPAR is not recommended for patients with CKD not receiving dialysis.
SENSIPAR should not be used in children. A death was reported in an adolescent clinical trial patient with very low calcium levels in the blood (hypocalcemia).
Interactions with this medication
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, even those not prescribed.

Proper use of this medication
It is important to take SENSIPAR exactly as your doctor has instructed you. Your doctor will tell you how much SENSIPAR to take. Your doctor will order regular blood tests to measure how you are responding to SENSIPAR and may increase or decrease your dose based on your PTH, calcium, and phosphate levels.
Usual Adult Dose:
If you have secondary hyperparathyroidism the usual starting dose for SENSIPAR is one 30 mg tablet once daily.
If you have parathyroid cancer or primary hyperparathyroidism, the usual starting dose for SENSIPAR is one 30 mg tablet twice daily.
SENSIPAR is taken once a day with food or right after a meal. SENSIPAR tablets must be taken whole and are not to be divided. It’s best to take SENSIPAR at the same time each day.
Tell your doctor or contact your regional Poison Control Centre immediately if you think you took more than the recommended dose of SENSIPAR.
In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.
