These highlights do not include all the information needed to use PEMETREXED FOR INJECTION safely and effectively. See full prescribing information for PEMETREXED FOR INJECTION.

PEMETREXED FOR INJECTION, for intravenous use
Initial U.S. Approval: 2004


Pemetrexed for Injection is a folate analog metabolic inhibitor indicated:

  • In combination with cisplatin for the initial treatment of patients with locally advanced or metastatic, non-squamous, non-small cell lung cancer (NSCLC). (1.1)
  • As a single agent for the maintenance treatment of patients with locally advanced or metastatic, non-squamous NSCLC whose disease has not progressed after four cycles of platinum-based first-line chemotherapy. (1.1)
  • As a single agent for the treatment of patients with recurrent, metastatic non-squamous, NSCLC after prior chemotherapy. (1.1)
  • Limitations of Use: Pemetrexed for Injection is not indicated for the treatment of patients with squamous cell, non-small cell lung cancer. (1.1)
  • Initial treatment, in combination with cisplatin, of patients with malignant pleural mesothelioma whose disease is unresectable or who are otherwise not candidates for curative surgery. (1.2)


  • The recommended dose of Pemetrexed for Injection, administered as a single agent or with cisplatin, in patients with creatinine clearance of 45 mL/minute or greater is 500 mg/m2 as an intravenous infusion over 10 minutes on Day 1 of each 21-day cycle. (2.1, 2.2)
  • Initiate folic acid 400 mcg to 1000 mcg orally, once daily, beginning 7 days prior to the first dose of Pemetrexed for Injection and continue until 21 days after the last dose of Pemetrexed for Injection. (2.4)
  • Administer vitamin B12, 1 mg intramuscularly, 1 week prior to the first dose of Pemetrexed for Injection and every 3 cycles. (2.4)
  • Administer dexamethasone 4 mg orally, twice daily the day before, the day of, and the day after Pemetrexed for Injection administration. (2.4)


For Injection: 100 mg, 500 mg or 1 gram lyophilized powder in a single-dose vial. (3)


History of severe hypersensitivity reaction to pemetrexed. (4)


  • Myelosuppression: Can cause severe bone marrow suppression resulting in cytopenia and an increased risk of infection. Do not administer Pemetrexed for Injection when the absolute neutrophil count is less than 1500 cells/mm3 and platelets are less than 100,000 cells/mm3. Initiate supplementation with oral folic acid and intramuscular vitamin B12 to reduce the severity of hematologic and gastrointestinal toxicity of Pemetrexed for Injection. (2.4, 5.1)
  • Renal Failure: Can cause severe, and sometimes fatal, renal failure. Do not administer when creatinine clearance is less than 45 mL/min. (2.3, 5.2)
  • Bullous and Exfoliative Skin Toxicity: Permanently discontinue for severe and life-threatening bullous, blistering or exfoliating skin toxicity. (5.3)
  • Interstitial Pneumonitis: Withhold for acute onset of new or progressive unexplained pulmonary symptoms. Permanently discontinue if pneumonitis is confirmed. (5.4)
  • Radiation Recall: Can occur in patients who received radiation weeks to years previously; permanently discontinue for signs of radiation recall. (5.5)
  • Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception. (5.7, 8.1, 8.3)


  • The most common adverse reactions (incidence ≥20%) of pemetrexed, when administered as a single agent, are fatigue, nausea, and anorexia. (6.1)
  • The most common adverse reactions (incidence ≥20%) of pemetrexed when administered with cisplatin are vomiting, neutropenia, anemia, stomatitis/pharyngitis, thrombocytopenia, and constipation. (6.1)

To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 or FDA at 1-800-FDA-1088 or


Ibuprofen increased risk of Pemetrexed for Injection toxicity in patients with mild to moderate renal impairment. Modify the ibuprofen dosage as recommended for patients with a creatinine clearance between 45 mL/min and 79 mL/min. (2.5, 5.6, 7)


Lactation: Advise not to breastfeed. (8.2)
