FDA-Approved Indications

KEYTRUDA is a prescription medicine used to treat:

  • a kind of lung cancer called non–small cell lung cancer (NSCLC).
    • It may be used in combination with chemotherapy that contains platinum and another chemotherapy medicine before surgery when you have early-stage NSCLC, which can be removed by surgery, and then continued alone after surgery to help prevent your lung cancer from coming back.
    • It may be used with the chemotherapy medicines pemetrexed and a platinum as your first treatment when your lung cancer has spread (advanced NSCLC) and is a type called “nonsquamous” and your tumor does not have an abnormal “EGFR” or “ALK” gene.
    • It may be used with the chemotherapy medicines carboplatin and either paclitaxel or paclitaxel protein-bound as your first treatment when your lung cancer has spread (advanced NSCLC) and is a type called “squamous.”
    • It may be used alone as your first treatment when your lung cancer has not spread outside your chest (stage III) and you cannot have surgery or chemotherapy with radiation, or your NSCLC has spread to other areas of your body (advanced NSCLC), and your tumor tests positive for “PD-L1” and does not have an abnormal “EGFR” or “ALK” gene.
    • It may also be used alone for advanced NSCLC if you have tried chemotherapy that contains platinum and it did not work or is no longer working and, your tumor tests positive for “PD-L1” and if your tumor has an abnormal “EGFR” or “ALK” gene, you have also received an “EGFR” or “ALK” inhibitor medicine that did not work or is no longer working.
    • It may be used alone as a treatment in adults for your lung cancer to help prevent your lung cancer from coming back after your tumor(s) has been removed by surgery and you have received platinum-based chemotherapy, and you have stage IB and your tumor(s) is 4 cm or greater in size, stage II, or stage IIIA NSCLC.
  • a kind of skin cancer called melanoma.
    • It may be used when your melanoma has spread or cannot be removed by surgery (advanced melanoma), or
    • It may be used in adults and children 12 years of age and older with stage IIB, stage IIC, or stage III melanoma, to help prevent melanoma from coming back after it and lymph nodes that contain cancer have been removed by surgery.
  • a kind of cancer called head and neck squamous cell cancer (HNSCC).
    • It may be used with the chemotherapy medicines fluorouracil and a platinum as your first treatment when your head and neck cancer has spread or returned and cannot be removed by surgery.
    • It may be used alone or as your first treatment when your head and neck cancer has spread or returned and cannot be removed by surgery, and your tumor tests positive for “PD-L1.”
    • It may be used alone when your head and neck cancer has spread or returned, and you have received chemotherapy that contains platinum and it did not work or is no longer working.
  • a kind of bladder and urinary tract cancer called urothelial cancer.
    • It may be used with the medicine enfortumab vedotin in adults when your bladder or urinary tract cancer has spread or cannot be removed by surgery (advanced urothelial cancer).
    • It may be used alone when your bladder or urinary tract cancer has spread or cannot be removed by surgery (advanced urothelial cancer), and you are not able to receive chemotherapy that contains platinum (medicines called either cisplatin or carboplatin).
    • It may be used alone when your bladder or urinary tract cancer has spread or cannot be removed by surgery (advanced urothelial cancer), and you have received chemotherapy that contains platinum, and it did not work or is no longer working.
    • It may be used alone when your cancer has not spread to nearby tissue in the bladder, but is at high-risk for spreading (high-risk, non-muscle invasive bladder cancer [NMIBC]) and when your tumor is a type called “carcinoma in situ” (CIS), and you have tried treatment with Bacillus Calmette-Guerin (BCG) and it did not work, and you are not able to or have decided not to have surgery to remove your bladder.
  • a kind of cancer that is shown by a laboratory test to be a microsatellite instability-high (MSI-H) or a mismatch repair deficient (dMMR) solid tumor. It may be used in adults and children to treat:
    • cancer that has spread or cannot be removed by surgery (advanced cancer), and
    • has progressed following treatment, and you have no satisfactory treatment options.

Important Safety Information

KEYTRUDA is a medicine that may treat certain cancers by working with your immune system. KEYTRUDA can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen any time during treatment or even after your treatment has ended.

Call or see your health care provider right away if you develop any signs or symptoms of the following problems or if they get worse. These are not all of the signs and symptoms of immune system problems that can happen with KEYTRUDA:

Lung problems: cough, shortness of breath, or chest pain.

Intestinal problems: diarrhea (loose stools) or more frequent bowel movements than usual; stools that are black, tarry, sticky, or have blood or mucus; or severe stomach-area (abdomen) pain or tenderness.

Liver problems: yellowing of your skin or the whites of your eyes; severe nausea or vomiting; pain on the right side of your stomach area (abdomen); dark urine (tea colored); or bleeding or bruising more easily than normal.

Hormone gland problems: headaches that will not go away or unusual headaches; eye sensitivity to light; eye problems; rapid heartbeat; increased sweating; extreme tiredness; weight gain or weight loss; feeling more hungry or thirsty than usual; urinating more often than usual; hair loss; feeling cold; constipation; your voice gets deeper; dizziness or fainting; changes in mood or behavior, such as decreased sex drive, irritability, or forgetfulness.

Kidney problems: decrease in the amount of your urine; blood in your urine; swelling of your ankles; loss of appetite.

Skin problems: rash; itching; skin blistering or peeling; painful sores or ulcers in your mouth or in your nose, throat, or genital area; fever or flu-like symptoms; swollen lymph nodes.

Problems can also happen in other organs and tissues. Signs and symptoms of these problems may include: chest pain; irregular heartbeat; shortness of breath; swelling of ankles; confusion; sleepiness; memory problems; changes in mood or behavior; stiff neck; balance problems; tingling or numbness of the arms or legs; double vision; blurry vision; sensitivity to light; eye pain; changes in eyesight; persistent or severe muscle pain or weakness; muscle cramps; low red blood cells; bruising.

Infusion reactions that can sometimes be severe or life-threatening. Signs and symptoms of infusion reactions may include chills or shaking, itching or rash, flushing, shortness of breath or wheezing, dizziness, feeling like passing out, fever, and back pain.

Rejection of a transplanted organ or tissue. Your health care provider should tell you what signs and symptoms you should report and they will monitor you, depending on the type of organ or tissue transplant that you have had.

Complications, including graft-versus-host disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with KEYTRUDA. Your health care provider will monitor you for these complications.

Getting medical treatment right away may help keep these problems from becoming more serious. Your health care provider will check you for these problems during treatment with KEYTRUDA. They may treat you with corticosteroid or hormone replacement medicines. They may also need to delay or completely stop treatment with KEYTRUDA if you have severe side effects.

Before you receive KEYTRUDA, tell your health care provider if you have immune system problems such as Crohn’s disease, ulcerative colitis, or lupus; have had an organ or tissue transplant, including corneal transplant, or have had or plan to have a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic); have had radiation treatment in your chest area; have a condition that affects your nervous system, such as myasthenia gravis or Guillain-Barré syndrome.

If you are pregnant or plan to become pregnant, tell your health care provider. KEYTRUDA can harm your unborn baby. If you are able to become pregnant, you will be given a pregnancy test before you start treatment. Use effective birth control during treatment with KEYTRUDA and for 4 months after your last dose of KEYTRUDA. Tell them right away if you think you may be pregnant or you become pregnant during treatment with KEYTRUDA.

Tell your health care provider if you are breastfeeding or plan to breastfeed. It is not known if KEYTRUDA passes into your breast milk. Do not breastfeed during treatment with KEYTRUDA and for 4 months after your last dose of KEYTRUDA.

Tell your health care provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
