Etelcalcetide - injection
Etelcalcetide - injection
This medication is used to treat increased amounts of a certain hormone (parathyroid) in people with long-term kidney disease who are on dialysis. Dialysis treatment usually causes higher than normal amounts of certain substances (such as parathyroid hormone, calcium, phosphorus) in your body. This medication works by decreasing how much parathyroid hormone your body makes. This effect helps lower calcium and phosphorus levels in your blood. Having the right amounts of parathyroid hormone, calcium, and phosphorus in your body can help prevent bone problems.
This medication is given by injection into a vein as directed by your doctor, usually 3 times each week at the end of dialysis treatment. The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. If you miss a regularly scheduled dialysis treatment, you should not receive this medication until the end of your next dialysis treatment.
If your doctor is switching you from treatment with cinacalcet (a different medication used to decrease parathyroid hormone) to this medication, the cinacalcet should be stopped at least 7 days before starting etelcalcetide.
Nausea or vomiting may occur. If either of these effects lasts or gets worse, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
