Know potential side effects

It’s important to know about the most common side effects to expect when you or your loved one are taking the NINLARO treatment combination* so that you can take steps to manage any side effects that occur with your healthcare provider.


The NINLARO treatment combination has been available since 2015 and has a well-established safety profile

In the clinical study, the side effects with the NINLARO treatment combinationwere comparable to side effects with the lenalidomide+dexamethasone combination alone.

Manageable tolerability was seen with the NINLARO treatment combination

Discontinuation rates due to adverse reactions were similar

13 percent vs 11 percent.

10% of people discontinued NINLARO permanently due to an adverse reaction.

Most people did not need to reduce their starting dose of NINLARO

Four orange people icons with one gray icon on the end to represent 3 out of 4 people who received the NINLARO® (ixazomib) combination did not need to reduce their starting dose or NINLARO at any point.

The NINLARO treatment combination included NINLARO+lenalidomide+dexamethasone; the lenalidomide+dexamethasone combination included placebo+lenalidomide+dexamethasone.

NINLARO may cause serious side effects, including:

  • Low platelet counts (thrombocytopenia) are common with NINLARO and can sometimes be serious. You may need platelet transfusions if your counts are too low. Tell your healthcare provider if you have any signs of low platelet counts, including bleeding and easy bruising.
  • Stomach and intestinal (gastrointestinal) problems. Diarrhea, constipation, nausea, and vomiting are common with NINLARO and can sometimes be severe. Call your healthcare provider if you get any of these symptoms and they do not go away during treatment with NINLARO. Your healthcare provider may prescribe medicine to help treat your symptoms.
  • Nerve problems are common with NINLARO and may also be severe. Tell your healthcare provider if you get any new or worsening symptoms including: tingling, numbness, pain, a burning feeling in your feet or hands, or weakness in your arms or legs.
  • Swelling is common with NINLARO and can sometimes be severe. Tell your healthcare provider if you develop swelling in your arms, hands, legs, ankles, or feet, or if you gain weight from swelling.
  • Skin reactions. Rashes are common with NINLARO. NINLARO can cause rashes and other skin reactions that can be serious and can lead to death. Tell your healthcare provider right away if you get a new or worsening rash, severe blistering or peeling of the skin, or mouth sores.
  • Thrombotic microangiopathy (TMA). This is a condition involving blood clots and injury to small blood vessels that may cause harm to your kidneys, brain, and other organs, and may lead to death. Get medical help right away if you get any of the following signs or symptoms during treatment with NINLARO: fever, bruising, nose bleeds, tiredness, or decreased urination.
  • Liver problems. Tell your healthcare provider if you get these signs of a liver problem: yellowing of your skin or the whites of your eyes; pain in your right upper-stomach area (abdomen).

Other common side effects of NINLARO include low white blood cell counts and bronchitis.

Tell your healthcare provider if you get new or worsening signs or symptoms of the following during treatment with NINLARO:

Managing side effects

There are steps that you may wish to discuss with your healthcare provider to help manage some of the most common side effects that you may experience when taking NINLARO in combination with lenalidomide+dexamethasone.

  • Nausea and vomiting: there are many ways to manage nausea/vomiting, including lifestyle changes such as changing some things you eat or drink. Ask your healthcare team for recommendations.
  • Constipation: after talking with your healthcare provider, you may be asked to modify your diet to include more liquids or change certain foods to reduce constipation.
  • Diarrhea: ask your healthcare team for specific recommendations for coping with diarrhea. Your team may suggest you eat certain foods and make changes to your overall diet to help reduce diarrhea.
  • Rash: it is important to immediately report rash or any skin changes to your healthcare team. Do not diagnose or treat yourself to avoid making the rash worse.

Talking to your doctor about side effects

Ask your healthcare provider if you have any questions about side effects or are having trouble managing side effects. Contact your healthcare provider immediately if you experience any serious side effects.
