Leucovorin Calcium 5 mg/1 is a critical medication in the management of certain types of anemia and in the treatment of folate deficiency when oral therapy is not feasible. It plays a vital role in DNA synthesis and repair, making it essential in medical settings where folate metabolism is disrupted.

Leucovorin Calcium 5 mg/1 is used to modulate the effects of other chemotherapeutic agents and to treat folate deficiency. It is primarily indicated for the following conditions:

- Methotrexate toxicity rescue: Reduces the toxic effects of high-dose methotrexate by replenishing folate levels in healthy cells. - Enhancement of 5-fluorouracil efficacy: Potentiates the cytotoxic effect of 5-fluorouracil in the treatment of colorectal cancer. - Folate deficiency: Treats megaloblastic anemia caused by folic acid deficiency when oral therapy is not feasible. - Leucovorin rescue in high-dose methotrexate therapy: Counteracts the effects of impaired methotrexate elimination or inadvertent overdose.

Leucovorin Calcium 5 mg/1 may cause several side effects, ranging from common to serious. Common Side Effects: - Nausea, vomiting, or diarrhea. - Mouth sores or irritation. - Fatigue or headache. - Rash, itching.
