What is the most important information I should know about ixazomib?
Do not use ixazomib with lenalidomide if you are pregnant, or if you are a man and your sexual partner is pregnant. Lenalidomide is known to cause severe, life-threatening birth defects or death of a baby if the mother or the father is taking this medicine at the time of conception or during pregnancy.
What is ixazomib?
Ixazomib is used in adults to treat multiple myeloma (bone marrow cancer), in combination chemotherapy with lenalidomide and dexamethasone.
This combination is usually given after treatment with at least one other cancer medicine has failed.
Ixazomib should not be used to treat people who are receiving maintenance treatment, or who have been newly diagnosed with multiple myeloma, except if they are participants in a controlled clinical trial.
Ixazomib may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before taking ixazomib?
You should not use ixazomib if you are allergic to it.
Tell your doctor if you have ever had:
- liver disease; or
- kidney disease (or if you are on dialysis).
Ixazomib may harm an unborn baby. Both men and women should use effective birth control to prevent pregnancy while taking ixazomib, and for at least 90 days after the last dose.
If you are a woman also taking dexamethasone: If you use birth control pills or other hormonal contraception (injections, implants, skin patches, vaginal rings), also use a barrier form of birth control such as a condom, diaphragm, cervical cap, or contraceptive sponge.
Ixazomib is used together with lenalidomide. Do not use ixazomib with lenalidomide if you are pregnant, or if you are a man and your sex partner is pregnant.
