Cinacalcet - oral


Patient Medicine Information
Why do I need this medicine?
Cinacalcet is used on its own or together with other medicines to treat hyperparathyroidism (high level of parathyroid hormone due to overactivity of parathyroid glands) in those with severe kidney disease who are undergoing dialysis.

This medicine is also used to reduce hypercalcaemia (high calcium level in the blood) in people with parathyroid cancer or hyperparathyroidism when surgical removal of the gland is not possible.
How do I take this medicine?
Take Cinacalcet exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

Take it together with food or immediately after a meal. Try to take it at the same time each day.

This medicine is available as a tablet or granules in capsules for opening.

If you are taking the tablet, swallow it whole. Do not divide, chew or crush the tablet.

If you have difficulty swallowing tablet(s), you may be given the granules in capsules for opening. Open the capsule and sprinkle the granules onto a small amount of soft foods or liquids such as apple sauce, yoghurt, or apple juice. Take the mixture immediately. Using water is not advisable as it may make Cinacalcet taste bitter. Do not swallow the capsule whole.

The dose of this medicine will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on your condition and response to the medication.

Cinacalcet must be taken regularly for it to be effective. Continue taking this medicine even when you feel better. Do not stop taking it unless instructed by the doctor.
What should I do if I have forgotten to take this medicine?
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.

DO NOT double a dose under any circumstances.

If you often forget to take your medicine, let your doctor and pharmacist know.
When should I not use this medicine?
Alert your doctor if you have hypocalcaemia (low calcium level in the blood) as Cinacalcet may not be suitable for you.

Do not take this medicine with etelcalcetide (other medicines used to treat high levels of parathyroid hormones).

Why is it important to keep my appointments with the doctor?

Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
  • Routine blood tests (e.g. blood calcium, phosphorus, or parathyroid hormone levels) may be done while you are being treated with Cinacalcet.
  • Regular monitoring for signs and symptoms of hypocalcaemia may also be needed.
Your doctor will advise you about how often you will need to have these tests.
