Pembrolizumab (Intravenous route)
Uses of This Medicine:
Pembrolizumab injection is used to treat melanoma (a type of skin cancer) that has spread or cannot be removed by surgery. It is also used to help prevent melanoma from coming back after it and lymph nodes affected by cancer have been removed by surgery in patients with Stage IIB, Stage IIC, or Stage III melanoma.
Pembrolizumab injection is used alone to treat non-small cell lung cancer (NSCLC) that has spread, whose tumors express PD-L1 and do not have an abnormal EGFR or ALK gene in patients who have not received other cancer treatments. It is also used alone to treat NSCLC that has spread, whose tumors express PD-L1 and have an abnormal EGFR or ALK gene in patients who have received other cancer medicines (eg, platinum) that did not work well. Pembrolizumab injection is also used alone as first-line treatment for stage III NSCLC in patients who cannot have surgery or chemotherapy with radiation or for NSCLC that has spread and whose tumors express PD-L1 without an abnormal EGFR or ALK gene. This medicine is also used in combination with pemetrexed and platinum-containing chemotherapy to treat NSCLC that has spread and whose tumors do not have an abnormal EGFR or ALK gene. Pembrolizumab injection is also used together with carboplatin and paclitaxel or nab-paclitaxel to treat squamous NSCLC that has spread.
Pembrolizumab injection is used in combination with platinum and fluorouracil as first-line treatment of head and neck squamous cell cancer (HNSCC) that has spread or cannot be removed by surgery. This medicine is also given to patients whose tumors express PD-L1 or patients who have received other cancer medicines (eg, platinum) that did not work well.
Pembrolizumab injection is used to treat relapsed (cancer that has come back) or refractory (cancer that did not respond to treatment) classical Hodgkin lymphoma (cHL) in adults. This medicine is also used to treat cHL in children who have tried a treatment that did not work, or whose cHL has returned after 2 or more previous lines of treatment.
Pembrolizumab injection is used to treat primary mediastinal large B-cell lymphoma (PMBCL) in patients who have tried a treatment that did not work, or whose PMBCL has returned after 2 or more previous lines of treatment.
Pembrolizumab injection is also used to treat urothelial carcinoma (a type of urinary tract cancer) that has spread throughout the body (metastatic) or cannot be removed by surgery (advanced). This medicine is given to patients who are not able to receive platinum-containing chemotherapy (eg, carboplatin or cisplatin) or patients who have received platinum-containing chemotherapy that did not work well. This medicine is also used to treat patients with high-risk Bacillus Calmette-Guerin (BCG)-unresponsive, high-risk, non-muscle invasive bladder cancer (NMIBC) with a tumor type called carcinoma in situ (CIS) with or without papillary tumors who cannot receive or have not decided to have surgery to remove the bladder.
Pembrolizumab injection is also used to treat microsatellite instability high (MSI-H) or mismatch repair deficient (dMMR) solid tumor that has spread or cannot be removed by surgery. It is given to patients who have received other cancer treatments that did not work well. This medicine is also used to treat MSI-H or dMMR colorectal cancer (CRC) that has spread or cannot be removed by surgery.
Pembrolizumab injection is also used in combination with other cancer treatments (eg, trastuzumab, fluoropyrimidine, platinum) as first-line treatment of gastric or gastroesophageal junction adenocarcinoma in patients whose cancer has an abnormal HER2 gene and has spread or cannot be removed by surgery.
Pembrolizumab injection is also used to treat esophageal or gastroesophageal junction carcinoma that cannot be cured by surgery or combination of chemotherapy and radiation. It is used in combination with other cancer treatments (eg, fluoropyrimidine, platinum) or alone in patients who have received 1 or more types of cancer treatment that did not work well and whose tumors are squamous and express PD-L1.
Pembrolizumab injection is used in combination with other cancer treatments, with or without bevacizumab, to treat cervical cancer that has returned or spread, or does not go away, and whose tumors express PD-L1. It is also used alone to treat cervical cancer that has returned or spread, and whose tumors express PD-L1 in patients who have received other cancer medicines that did not work well.
Pembrolizumab injection is also used to treat a type of liver cancer called hepatocellular carcinoma (HCC) in patients who have been previously treated with sorafenib that did not work well.
Pembrolizumab injection is also used to treat a kind of skin cancer called Merkel cell carcinoma (MCC) that has returned or spread, or cutaneous squamous cell carcinoma (cSCC) that has returned or spread and cannot be cured by surgery or radiation.
Pembrolizumab injection is also used in combination with other cancer treatments (eg, axitinib, lenvatinib) as first-line treatment of advanced renal cell carcinoma (RCC), a kind of kidney cancer, in patients whose cancer has spread or cannot be removed by surgery. It is also used alone to treat kidney cancer in patients who are at intermediate-high or high risk of the cancer coming back after surgery to remove all or part of your kidney, or remove all or part of your kidney and surgery to remove cancer that has spread to other parts of the body (metastatic lesions).
Pembrolizumab injection is also used in combination with lenvatinib to treat advanced endometrial cancer (cancer of the lining of the uterus or womb) that is not MSI-H or dMMR, in patients who have received other cancer medicines but did not work well and cannot be removed by surgery or radiation.
Pembrolizumab injection is also used to treat a type of cancer called tumor mutational burden-high (TMB-H) in patients whose solid tumors have spread or cannot be removed by surgery. It is given to patients who have received other cancer treatments that did not work well and who have no other treatment options.
Pembrolizumab injection is also used together with other cancer medicines before surgery and then continued alone after surgery to treat patients with early-stage triple-negative breast cancer (TNBC) and who are at high risk of the cancer coming back. It is also used together with other cancer medicines to treat patients with TNBC that has spread or cannot be removed by surgery and whose tumors express PD-L1.
Pembrolizumab is a monoclonal antibody that changes the immune system to help control the growth of cancer cells.
This medicine is to be given only by or under the direct supervision of your doctor.
Before Using This Medicine:
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 this medicine, the following should be considered:

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 performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of pembrolizumab injection in children 12 years of age with melanoma or in children with lymphoma, solid tumors, colorectal cancer, Merkel cell carcinoma, microsatellite instability-high cancer, or tumor mutational burden-high cancer. However, safety and efficacy have not been established in children with other cancers.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of pembrolizumab injection in the elderly. However, elderly patients are more likely to have serious unwanted effects, which may require caution in patients receiving this medicine.
