What is levoleucovorin (Fusilev)?
Levoleucovorin is used to treat or prevent toxic effects of methotrexate in people who have received methotrexate to treat bone cancer.
Levoleucovorin is also used to treat or prevent toxic effects of methotrexate in people whose bodies do not eliminate methotrexate properly after the drug is metabolized. Levoleucovorin may also be used to treat toxic effects of an accidental overdose of methotrexate.
Levoleucovorin is also used in combination chemotherapy with fluorouracil (5-FU, Adrucil, Efudex, Carac, Fluoroplex) to treat colorectal cancer that has spread to other parts of the body. Levoleucovorin treats only the symptoms of colorectal cancer but does not treat the cancer itself.
