Neutrexin (trimetrexate glucuronate for injection) administered without concurrent leucovorin can cause lethal complications. There has been no extensive experience in humans receiving single intravenous doses of trimetrexate greater than 90 mg/m2/day with concurrent leucovorin. The toxicities seen at this dose were primarily hematologic. In the event of overdose, Neutrexin (trimetrexate glucuronate inj) should be stopped and leucovorin should be administered at a dose of 40 mg/m2 every 6 hours for 3 days. The LD50 of intravenous trimetrexate in mice is 62 mg/kg (186 mg/m2).


Neutrexin (trimetrexate glucuronate for injection) is contraindicated in patients with clinically significant sensitivity to trimetrexate, leucovorin, or methotrexate.

This monograph has been modified to include the generic and brand name in many instances.
