What is Opdivo (nivolumab) used for?

How Opdivo (nivolumab) works

Opdivo (nivolumab) is an immunotherapy medication. In particular, it's called a programmed death-1 inhibitor, or PD-1 inhibitor. It's also called a checkpoint inhibitor.

Opdivo (nivolumab) works by blocking the programmed death-1 (PD-1) pathway. Some cancer cells use the PD-1 pathway to hide from the immune system. When this happens, the immune system can't find and destroy the cancer cells as well. And so, the cancer can grow.

By blocking the PD-1 pathway, Opdivo (nivolumab) helps the immune system find cancer cells and kill them better. This helps stop the cancer from growing.

Pharmacist tips for Opdivo (nivolumab)

pharmacist
  • Put your Opdivo (nivolumab) infusion appointments into your calendar. Depending on your cancer and treatment plan, your infusions will be once every few weeks. If you miss an appointment, call the clinic as soon as possible to reschedule.
  • Each Opdivo (nivolumab) infusion takes about 30 minutes. But your visit might be longer because you'll need time to get settled. Plan extra time for your appointments, and bring something to do, like a book or an electronic device.
  • Get your lab tests done on time while taking Opdivo (nivolumab). These tests help your oncology care team check for side effects you might not notice very easily. These side effects can include liver, kidney, or thyroid problems.
  • Tell your oncology care team right away if you have any immune-related side effects while taking Opdivo (nivolumab). These can include rash, itching, trouble breathing, coughing, or diarrhea. You might need extra medical care to help manage these symptoms.
  • Don’t take any over-the-counter (OTC) medications for Opdivo (nivolumab) side effects without talking to your oncology care team first. OTC medications, like loperamide (Imodium A-D) for diarrhea, might not be enough to help. You might need a steroid or other supportive treatments to help you feel better.
  • If you need to take a steroid for a few weeks to help with side effects, be sure to follow your prescriber's directions. Don't stop taking it suddenly because it could cause stomach cramps and body aches. Your prescriber will help you slowly lower the dose so you can stop the steroid safely.
  • It's not common, but some people might have a reaction during their Opdivo (nivolumab) infusion. Tell your nurse right away if you have chills, flushing, trouble breathing, or itching. Your care team can treat the reaction quickly and slow the infusion if needed.
  • If you can get pregnant, use reliable birth control while taking Opdivo (nivolumab). Keep using birth control for 5 months after your last infusion of the medication. Opdivo (nivolumab) can harm an unborn baby. Tell your oncology care team right away if you become pregnant during treatment.
  • Don’t breastfeed while taking Opdivo (nivolumab) and for 5 months after your last infusion. It's not known if the medication can pass into breast milk. But if it can, there's a potential risk that it can cause side effects in your baby. Talk to your oncologist or a lactation consultant about safer feeding options.

Common questions about Opdivo (nivolumab)

Opdivo (nivolumab) is a type of immunotherapy. It works in a different way than traditional chemotherapy. Traditional chemotherapy kills any fast-growing cells in the body, including cancer cells. Immunotherapy helps your own immune system fight cancer. Opdivo (nivolumab) helps your immune system find and destroy cancer cells better.

Each dose of Opdivo (nivolumab) can stay in your system for about 4 months. This is based on its half-life, or how long it takes for half the medication to clear from your body. If you're worried about how long the medication stays in your system, ask your oncologist.

How long Opdivo (nivolumab) side effects last can be different for everyone. It depends on how severe the side effect is and how well you respond to supportive treatment. For example, your oncologist might give you a steroid like prednisone to help. For rashes and itching, moisturizing creams or topical steroids might help. Tell your oncology care team if you have any side effects that bother you. They can find ways to help with side effects.

Yes, Opdivo (nivolumab) can sometimes cause thyroid problems. It can make your thyroid too active or not work as well. This is one of the medication's immune-related side effects. Thyroid problems can cause mood changes like feeling nervous, irritable, or tired. They can also make you more sensitive to heat or cold. Sometimes, people don't have these symptoms or they're hard to notice. That's why you'll need regular blood tests to check your thyroid function during treatment. Be sure to get these blood tests when asked. Talk to your oncologist if you have questions about your lab results.

No, Opdivo (nivolumab) can't cure cancer. It can't remove all of the cancer. But studies show that it can help slow cancer growth and keep the cancer from getting worse as quickly. Talk to your oncologist about how Opdivo (nivolumab) might help with the type of cancer you have.

It's best to limit alcohol while taking Opdivo (nivolumab). Avoiding alcohol completely is even better. Alcohol can raise your risk of cancer. It might weaken your immune system, which could potentially affect how well the medication works. Talk to your oncologist about your drinking habits. If stopping is hard for you, they can offer support and resources to help.

How long you take Opdivo (nivolumab) depends on your type of cancer and your treatment plan. It also depends on how well the medication is working, whether you have any side effects, and how severe they are. Some people take Opdivo (nivolumab) for a specific amount of time or a set number of doses or cycles. Other people take it with no planned end date and continue as long as it helps and side effects are manageable. Your oncologist will check your symptoms, lab tests, and scans to see how well the medication is working. Talk to your care team about any side effects. Ask your oncologist about how long you'll take Opdivo (nivolumab).

Keytruda (pembrolizumab) and Opdivo (nivolumab) are both types of immunotherapy that work in similar ways. They're given as infusions through the vein every few weeks at a medical center. They can also cause similar side effects like rash, diarrhea, and trouble breathing. But Keytruda is generally approved to treat more types of cancers than Opdivo. Both medications can be used alone or with other cancer treatments. But unlike Keytruda, Opdivo is sometimes used with another immunotherapy medication called Yervoy (ipilimumab) for certain cancers. Talk to your oncologist to learn more about how the two compare.

Risks and warnings for Opdivo (nivolumab)

Opdivo (nivolumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Immune-related side effects

Immunotherapy medications such as Opdivo (nivolumab) can cause immune-related adverse events (irAEs). These side effects happen when your immune system becomes too active. It causes your immune system to start attacking healthy cells, not just cancer cells.

These side effects can happen anywhere in your body and at any time while you're taking Opdivo (nivolumab). They can be mild or very serious.

Some side effects show up on your blood test results. These include liver or kidney problems. That's why it's important to get your blood work done on time, even if you feel fine. This helps your care team look for side effects that you might not notice on your own.

Other side effects can cause symptoms you can feel. Examples include diarrhea, rash, and trouble breathing. Tell your care team right away if you notice these symptoms or anything unusual. Depending on how severe your symptoms are, you might need to stop Opdivo (nivolumab) for a while and take a steroid to help you feel better.

Infusion-related reactions

Some people taking Opdivo (nivolumab) can have a reaction during the infusion. Most reactions are mild or moderate. But in rare cases, they can be severe or life-threatening.

The nurse will watch for these reactions while you're getting your infusion. Tell them right away if you start feeling itchy, warm, or nauseous during your infusion. Also let them know if you feel your heart racing or have trouble breathing.

Usually, slowing or pausing the infusion can help manage these infusion reactions so you can keep taking Opdivo (nivolumab). But if the reaction is severe, you might need to stop the medication altogether.

Complications from stem cell transplants

  • Risk factors: People who’ve had a stem cell (bone marrow) transplant

Some people who’ve taken immunotherapy medications like Opdivo (nivolumab) and had a stem cell transplant can have serious problems. This can include liver damage called veno-occlusive disease (VOD). It can also lead to graft-versus-host disease (GVHD).

Before starting Opdivo (nivolumab), tell your oncology care team if you’ve had a stem cell transplant before. Also let them know if you have one planned at any time after you're done with Opdivo (nivolumab). Your care team will check on you regularly for any signs of these problems.

Harm to an unborn baby

  • Risk factors: Pregnancy

Based on animal studies and the way Opdivo (nivolumab) works, this medication might harm an unborn baby when it’s given during pregnancy.

If you can get pregnant, your oncologist might ask you to take a pregnancy test before you start treatment. This double checks you're not pregnant before starting Opdivo (nivolumab).

Then once you start Opdivo (nivolumab), use effective birth control if you're having sex. Keep using birth control for 5 more months after your last dose. Tell your care team right away if you become pregnant at any time during treatment.
