Durvalumab is an immunotherapy drug. It is used to treat lung cancer. It may also be used to treat other types of cancer.
Durvalumab is usually used to treat lung cancer.
It can be used to treat non-small cell lung cancer that cannot be removed with surgery and has not grown after finishing chemoradiation. Your doctor will arrange for tests on the lung cancer cells (from a biopsy) to find out if durvalumab is likely to be a helpful treatment for you.
Durvalumab may sometimes be used to treat other cancers, such as bladder cancer and head and neck cancer. You may have it as part of a clinical trial. It is best to read this information with our general information about the type of cancer you have.
Durvalumab 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 usually be given durvalumab at a day unit as an outpatient. Durvalumab can be given on its own or with other cancer drugs.
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.
Durvalumab is given as a drip into a vein (intravenous infusion). It is given over 1 hour.
Your course of chemotherapy
How often you have dacarbazine depends on the type of cancer being treated. Your nurse or doctor will discuss your treatment plan with you. You usually have a course of several cycles of treatment over a few months.
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.
Sometimes side effects can become serious very quickly. It is important to contact the hospital straight away if you have new symptoms or side effects.
We cannot list every side effect for this treatment. There are some rare side effects that are not listed. You can visit the electronic Medicines Compendium (eMC) for more detailed information.

They can give you mouthwashes, medicines and gels to heal ulcers and clear or prevent any infection. Your nurse will explain how to look after your mouth to reduce the risk of problems.
The most common mouth infection is called thrush (or candidiasis). It shows as white spots on your mouth and tongue, or your tongue and mouth lining become red and swollen.

You can help reduce the risk of developing a blood clot by:
- staying active during treatment

You may be given anticoagulants to help prevent a clot.
Some medicines can affect how this treatment works or be harmful when you are having it. Always tell your cancer doctor about any drugs you are taking or planning to take, such as:
- 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 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, such as shingles, 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 doctors and nurses you are having cancer treatment. 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.
