Documented Uses

• For the treatment of osteosarcoma (after high dose methotrexate therapy). Used to diminish the toxicity and counteract the effects of impaired methotrexate elimination and of inadvertent overdosages of folic acid antagonists, and to treat megaloblastic anemias due to folic acid deficiency. Also used in combination with 5-fluorouracil to prolong survival in the palliative treatment of patients with advanced colorectal cancer. Used in cancer chemotherapy involving the drug methotrexate.
• Breast Feeding; Lactation; Milk, Human; Antidotes; Vitamin B Complex; Vitamins
• Leucovorin calcium is approved to be used alone or with other drugs to treat:
• • Colorectal cancer. It is used with fluorouracil as palliative treatment in patients with advanced disease.
• • Anemia. It is used to treat megaloblastic anemia that occurs when the body does not get enough of a vitamin called folic acid. It is used by patients who cannot take the vitamin by mouth.
• Leucovorin calcium is also used to prevent and treat the toxic effects of high-dosemethotrexate when used to treat osteosarcoma and other types of cancer. It is also used to treat overdoses of methotrexate or other folic acid antagonists. The drug is also being studied in the treatment of other conditions and types of cancer.
