What is Kyprolis?

Kyprolis (carfilzomib) is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Kyprolis is used to treat multiple myeloma. It is sometimes given in conjunction with other medicines when treating relapsed multiple myeloma.

Kyprolis is usually given after at least two other cancer medicines have been tried without success.

Important information

Kyprolis can affect your heart or lungs. Call your doctor at once if you have chest pain, pounding heartbeats, shortness of breath (even with mild exertion or while lying down), swelling of your hands or feet, feeling like you might pass out, wheezing, gasping for breath, cough with foamy mucus, or blue colored appearance of your lips and skin.

Before taking this medicine

You should not use Kyprolis if you are allergic to carfilzomib.

To make sure Kyprolis is safe for you, tell your doctor if you have:

  • kidney disease (or if you are on dialysis);

  • heart disease, high blood pressure; or

  • liver disease, or abnormal liver function tests.

Kyprolis can harm an unborn baby. Use effective birth control to prevent pregnancy while you are using this medicine, whether you are a man or a woman. Kyprolis use by either parent may cause birth defects.

If you are a woman, keep using birth control for at least 30 days after your last dose of carfilzomib. If you are a man, keep using birth control for at least 90 days after your last dose. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using this medicine.

It is not known whether carfilzomib passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using Kyprolis.

How is Kyprolis given?

Kyprolis is injected into a vein through an IV. A healthcare provider will give you this injection.

Kyprolis is given in a 28-day treatment cycle. You will receive an injection only on certain days of this cycle.

Your doctor will determine how many treatment cycles you should receive.

You may be given medication to prevent certain side effects while you are receiving Kyprolis. Drink plenty of liquids before and after your Kyprolis injections.

Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while receiving this medication.

You may need frequent medical tests to be sure Kyprolis is not causing harmful effects. Your cancer treatments may be delayed based on the results of these tests.
