Why is this medication prescribed?
Adults with chronic kidney disease (condition in which the kidneys stop working slowly and gradually) who are receiving dialysis (medical procedure to clean the blood when the kidneys are not working properly) are treated for secondary hyperparathyroidism with etelcalcetide injection. Secondary hyperparathyroidism is a condition in which the body produces excessive amounts of parathyroid hormone (PTH; natural substance needed to control the amount of calcium in the blood). Etelcalcetide injection belongs to the group of drugs known as calcimimetics. In order to lower the level of calcium in the blood, it signals the body to create less parathyroid hormone.
How should this medicine be used?
A solution (liquid) to be injected intravenously (into a vein) is how etelcalcetide injection is delivered. It is typically administered by a doctor or nurse at the dialysis centre three times each week at the conclusion of each dialysis session.
Your doctor will likely start you on an average dose of etelcalcetide injection and gradually increase or decrease it, not more frequently than once every four weeks, depending on how your body responds to the medication.

What special precautions should I follow?
Before receiving etelcalcetide injection,
- If you have an allergy to etelcalcetide, any other medications, or any of the substances in etelcalcetide injection, let your doctor and chemist know right away. Request a list of the ingredients from your chemist.
- Inform your doctor and chemist about any additional prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are now taking or intend to use. Additionally, let your doctor or chemist know if you are currently taking cinacalcet (Sensipar) or have recently stopped using it.

- Inform your doctor if you have or have ever had long QT syndrome, heart failure, low potassium or magnesium levels in the blood, seizures, stomach ulcers, any type of irritation or swelling of the stomach or oesophagus (tube that connects the mouth and stomach), or severe headaches. Long QT syndrome increases the risk of developing an irregular heartbeat that may cause loss of consciousness or sudden death.
- Inform your doctor if you are expecting, intend to get pregnant, or are nursing a baby. Call your doctor if you get pregnant while having etelcalcetide injection.
- Inform the surgeon or dentist that you are receiving an etelcalcetide injection if you are undergoing surgery, including dental surgery.
