What is Ninlaro?

Ninlaro is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Ninlaro 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.

Ninlaro 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.


Do not use Ninlaro 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.

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.

Before taking this medicine

You should not use Ninlaro if you are allergic to ixazomib.

To make sure Ninlaro is safe for you, tell your doctor if you have ever had:

Ixazomib may harm an unborn baby. Both men and women should use effective birth control to prevent pregnancy while taking Ninlaro, 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.

Ninlaro is used together with lenalidomide. Do not use Ninlaro with lenalidomide if you are pregnant, or if you are a man and your sex 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.

Carefully follow all instructions about the use of birth control while using Ninlaro with lenalidomide, whether you are a man or a woman. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using these medicines.

Do not breastfeed while using Ninlaro, and for at least 90 days after your last dose.

How should I take Ninlaro?

Take Ninlaro exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Your combination chemotherapy will be given in a 28-day treatment cycle. You will take Ninlaro once per week on the same day of the week during the first 3 weeks of each cycle. Your other medicines may be taken daily or only once per week throughout the cycle.

If you've ever had chickenpox or shingles, taking Ninlaro can cause this virus to become active again. You may be given antiviral medication to prevent shingles.

Carefully follow your doctor's dosing instructions for taking all your medications.

Take Ninlaro at the same time each day on an empty stomach, at least 1 hour before or 2 hours after a meal.

Do not take your dexamethasone dose at the same time you take Ninlaro. Dexamethasone should be taken with food and Ninlaro should be taken without food.

Swallow the Ninlaro capsule whole and do not crush, chew, break, or open it. Take with a full glass of water.

If you vomit shortly after taking Ninlaro, do not take another dose. Wait until your next scheduled dose time to take the medicine again.

Do not use a broken capsule. The medicine inside the capsule can be dangerous if it gets in your eyes or on your skin. If this happens, wash your skin with soap and water or rinse your eyes with water. Ask your pharmacist how to safely dispose of a broken pill.

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

Store at room temperature away from moisture and heat. Do not freeze. Keep each capsule in the blister pack until you are ready to take a dose.
