Uses for durvalumab

Durvalumab injection is used to treat non-small cell lung cancer (NSCLC) that has not spread and cannot be removed by surgery. It is given to patients who have received other cancer medicines (eg, platinum) and radiation treatment for their NSCLC. Durvalumab is also used in combination with etoposide and either carboplatin or cisplatin as first-line treatment for extensive-stage small cell lung cancer (ES-SCLC).

Durvalumab is to be given only by or under the supervision of your doctor.

Before using durvalumab

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For durvalumab, the following should be considered:


Tell your doctor if you have ever had any unusual or allergic reaction to durvalumab or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Appropriate studies have not been performed on the relationship of age to the effects of durvalumab injection in the pediatric population. Safety and efficacy have not been established.


Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of durvalumab injection in the elderly.


There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Interactions with food/tobacco/alcohol

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Other medical problems

The presence of other medical problems may affect the use of durvalumab. Make sure you tell your doctor if you have any other medical problems, especially:

  • Adrenal gland problems or
  • Diabetes or
  • Immune system problems or
  • Infection or
  • Kidney problems or
  • Liver problems or
  • Lung or breathing problems or
  • Thyroid problems—Use with caution. May make these conditions worse.
  • Patients who have had allogeneic hematopoietic stem cell transplant (HSCT)—Use with caution. May cause side effects to become worse.

Proper use of durvalumab

Medicines used to treat cancer are very strong and can have many side effects. Before using durvalumab, make sure you understand all the risks and benefits. It is important for you to work closely with your doctor during your treatment.

A nurse or other trained health professional will give you durvalumab. It is given through a needle placed into one of your veins. It must be given slowly, so the needle will have to remain in place for at least 60 minutes every 2, 3, or 4 weeks.

Durvalumab should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor if you have any questions.

Precautions while using durvalumab

It is very important that your doctor check your progress at regular visits to make sure that durvalumab is working properly. Blood and urine tests may be needed to check for unwanted effects.

Receiving durvalumab while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment with durvalumab and for at least 3 months after the last dose. If you think you have become pregnant while receiving the medicine, tell your doctor right away.

Tell your doctor right away if you have a cough, chest tightness, or any type of breathing problem with durvalumab. These could be symptoms of a serious lung problem (eg, pneumonitis).

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, a loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Colitis (inflammation of the colon) may occur with durvalumab. Tell your doctor right away if you have stomach pain or tenderness, watery or bloody diarrhea, or a fever after receiving the medicine.

Adrenal, pituitary, or thyroid gland problems may occur while you are receiving durvalumab. Tell your doctor if you have changes in mood or behavior, constipation, dry skin or hair, feeling cold, sensitivity to heat, sweating, trouble sleeping, or weight changes.

Check with your doctor right away if you have bloody urine, a decrease in frequency or amount of urine, an increase in blood pressure, increased thirst, loss of appetite, lower back or side pain, nausea, swelling of the face, fingers, or lower legs, trouble breathing, unusual tiredness or weakness, vomiting, or weight gain. These could be symptoms of a serious kidney problem.

Serious skin reactions (eg, exfoliative dermatitis, Stevens-Johnson syndrome, drug rash with eosinophilia and systemic syndrome (DRESS), or toxic epidermal necrolysis) can occur with durvalumab. Check with your doctor right away if you have blistering, peeling, or loosening of the skin, chills, cough, diarrhea, itching, joint or muscle pain, red irritated eyes, red skin lesions, often with a purple center, severe acne or a skin rash, sore throat, sores or ulcers on the skin, mouth, or lips, swollen glands, unusual bleeding or bruising, or unusual tiredness or weakness with durvalumab.

Check with your doctor right away if you have severe headache, drowsiness, confusion, general feeling of illness, or stiff neck or back while you are receiving durvalumab. These may be symptoms of meningitis.

Call your doctor right away if you start to have a cough that won't go away, weight loss, night sweats, fever, chills, painful or difficult urination, or flu-like symptoms, such as a runny or stuffy nose, headache, blurred vision, or feeling generally ill. These may be signs that you have an infection.

Durvalumab may cause inflammation of the heart muscle (myocardium) called myocarditis. Check with your doctor right away if you have chest pain or discomfort, fever, chills, a fast heartbeat, or trouble breathing.

Durvalumab may cause thrombocytopenic purpura. Check with your doctor right away if you have black, tarry stools, blood in the urine, bloody nose, fever, heavier menstrual periods, pinpoint red spots on the skin, skin rash, unusual bleeding or bruising or unusual tiredness or weakness.

Call your doctor right away if you have difficulty with breathing, swallowing, or talking, muscle weakness, severe tiredness, or sudden numbness and weakness in the arms or legs. These could be symptoms of a nervous system problem.

Durvalumab may cause a rare but serious type of an allergic reaction called an infusion reaction. This can be life-threatening and requires immediate medical attention. Tell your doctor right away if you start to have a skin rash, dizziness, trouble breathing, chest tightness, swelling in your face or hands, fever or chills while you are receiving durvalumab.

Durvalumab may increase your risk for possible organ transplant rejection. Talk to your doctor about this risk.
