Ipilimumab (YERVOY®) is used to treat:
- advanced melanoma
- advanced kidney cancer (renal cell cancer)
- non-small cell lung cancer (NSCLC)
- pleural mesothelioma.
It may sometimes be used to treat other cancers. It is best to read this information with our general information about the type of cancer you have.
Ipilimumab is an immunotherapy drug. It may also be called a checkpoint inhibitor. Your doctor will talk to you about this treatment and the possible side effects before you agree (consent) to have treatment.
You will be given ipilimumab at a day unit as an outpatient. Ipilimumab can be given on its own or with other cancer drugs such as nivolumab.
During treatment you usually see a cancer doctor, a specialist nurse, and a specialist pharmacist. This is who we mean when we mention doctor, nurse or pharmacist in this information.
Before, or on the day of, treatment, a nurse or person trained to take blood (phlebotomist) may take a blood sample from you.
You will see a doctor or nurse before you have treatment. They will talk to you about your blood results and ask you how you have been feeling. If your blood results are okay, the pharmacist will prepare your treatment.
Ipilimumab is given as a drip into a vein (intravenous infusion). It is given over about 90 minutes.
Your course of treatment
We explain the main side effects of this treatment here. We also include some other possible side effects.
You may get some of the side effects we mention, but you are unlikely to get all of them. If you are also having treatment with other cancer drugs, you may have some side effects that we have not listed here. Always tell your doctor, nurse or pharmacist about any side effects you have.
Your doctor can give you drugs to help control some side effects. It is important to take them exactly as your nurse or pharmacist explains. This means they will be more likely to work for you. Your nurse will give you advice about managing your side effects. After your treatment is over, most side effects start to improve.
Serious or delayed side effects
Some cancer treatments can cause severe side effects. Rarely, these may be life-threatening. Your doctor or nurse can explain the risk of these side effects to you.
This treatment may cause delayed side effects. These can start weeks, months, or sometimes more than a year, after you finish treatment.
If you have any symptoms or side effects that start during treatment or after treatment finishes, contact your doctor or hospital straight away. Side effects can become serious if they are not treated.
Your patient alert card
Your doctor, nurse or pharmacist will give you a card with information about your treatment on it. It is important to always have the card with you during treatment and after treatment finishes. You should show it to any doctor or healthcare professional you need to see.
Contact the hospital
Your nurse will give you telephone numbers for the hospital. If you feel unwell or need advice, you can call at any time of the day or night. Save these numbers in your phone or keep them somewhere safe.

- pale skin
- lack of energy
- feeling breathless
- feeling dizzy and light-headed.
Tell your doctor or nurse if you have these symptoms.
If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.
Blood clot risk
Cancer and some cancer treatments can increase the risk of a blood clot. Symptoms of a blood clot include:
- throbbing pain, redness or swelling in a leg or arm
- suddenly feeling breathless or coughing

You can help reduce the risk of developing a blood clot by:

- medicines you have been prescribed
- medicines you buy in a shop or chemist
- vitamins, herbal drugs and complementary therapies.
Tell other doctors, pharmacists or dentists who prescribe or give you medicines that you are having this cancer treatment.
You can visit the electronic Medicines Compendium (eMC) for more detailed information about your treatment.
Vaccinations can reduce your risk of getting certain infections. Your doctor or nurse may talk to you about having vaccinations.
Doctors usually recommend that people with cancer have a flu vaccination and a coronavirus (covid) vaccination. These are both inactivated vaccinations that can help reduce the risk of infection. People with weak immune systems can have these, as they are not live vaccinations.
If your immune system is weak, you need to avoid live vaccinations. This is because they can make you unwell. Live vaccines contain a very weak version of the illness they are vaccinating you against. Your cancer doctor or GP can tell you more about live and inactivated vaccinations.
Your doctor will advise you not to get pregnant or make someone pregnant while having this treatment. The drugs may harm a developing baby. It is important to use contraception during your treatment and for a while after treatment finishes. Your doctor, nurse or pharmacist can tell you more about this.
You are advised not to breastfeed while having this treatment, or for some time after treatment finishes. This is because the drugs could be passed to the baby through breast milk.
Your doctor or nurse can give you more information.
Medical and dental treatment
If you need medical treatment for any reason other than cancer, always tell the doctor and nurse that you are having cancer treatment. Show them your Patient Alert Card. Give them the contact details for your cancer doctor so they can ask for advice.
If you think you need dental treatment, talk to your cancer doctor or nurse. Always tell your dentist you are having cancer treatment.
