What is the most important information I should know about ixazomib?
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Do not use ixazomib with lenalidomide if you are pregnant, or if you are a man and your sexual partner is pregnant.

What is ixazomib?
Ixazomib is a cancer medicine that interferes with the growth and spread of cancer cells in the body.
Ixazomib is used to treat multiple myeloma (bone marrow cancer), in combination chemotherapy with lenalidomide and dexamethasone. This combination is usually given after at least one other cancer medicine has been tried without success.
Ixazomib may also be used for purposes not listed in this medication guide.

Even one dose of lenalidomide can cause major birth defects. Do not take ixazomib with lenalidomide if you are pregnant.
