Why is this medication prescribed?

Leucovorin, also known as folinic acid, is a medication that is often prescribed in combination with certain chemotherapy drugs to enhance their effectiveness and reduce their side effects. It is commonly used in the treatment of colorectal cancer, as well as other cancers such as osteosarcoma and pancreatic cancer. Leucovorin is a form of folic acid, a B-vitamin that plays a crucial role in DNA synthesis and repair.

Here are some reasons why Leucovorin Injection may be prescribed:

• Methotrexate Rescue: Leucovorin is often used as a “rescue” drug to counteract the toxic effects of high doses of methotrexate, a chemotherapy medication. It helps protect healthy cells from the harmful effects of methotrexate while allowing cancer cells to be affected by the chemotherapy.
• Colorectal Cancer: Leucovorin is commonly used in combination with fluorouracil (5-FU) as part of a chemotherapy regimen for colorectal cancer.
• Osteosarcoma: It may be used in the treatment of osteosarcoma, a type of bone cancer.
