Leucovorin: Uses, Dosage, And Side Effects
Leucovorin, also known as folinic acid, is a medication used to counteract the toxic effects of certain drugs, particularly methotrexate. It is a derivative of folic acid and plays a crucial role in various biochemical processes within the body.
What is Leucovorin?
Leucovorin is a rescue medication often administered after high doses of methotrexate, a chemotherapy drug. Methotrexate inhibits dihydrofolate reductase, an enzyme essential for DNA and RNA synthesis. By providing an alternative source of folate, leucovorin helps normal cells recover from the effects of methotrexate, reducing its toxicity.
Uses of Leucovorin
Leucovorin is primarily used in the following scenarios:
- Methotrexate Overdose: To reduce the toxicity and counteract the effects of accidental or intentional methotrexate overdose.
- High-Dose Methotrexate Therapy: As a rescue medication following high-dose methotrexate treatment for certain cancers, such as leukemia and lymphoma.
- Fluorouracil (5-FU) Chemotherapy: In combination with 5-FU to enhance its effectiveness in treating colorectal cancer. Leucovorin modulates 5-FU activity, leading to improved outcomes.
- Folate Deficiency: To treat folate deficiency caused by certain medications or medical conditions.
Dosage and Administration
The dosage of leucovorin varies depending on the specific clinical situation and the patient's individual needs. It is typically administered intravenously or orally. The timing and dosage are carefully determined by healthcare professionals based on factors such as: — Edge Imaging CA: How To Place Your Order

Side Effects
Leucovorin is generally well-tolerated, but some potential side effects may occur. Common side effects include:
- Nausea
- Vomiting
- Diarrhea
- Mouth sores
Less common but more serious side effects may include allergic reactions, such as rash, itching, swelling, or difficulty breathing. If any signs of an allergic reaction occur, seek immediate medical attention.
Drug Interactions
Leucovorin can interact with certain medications, potentially affecting their efficacy or increasing the risk of side effects. It is essential to inform your healthcare provider about all medications you are taking, including prescription drugs, over-the-counter medications, and herbal supplements. — Dushyant Chautala: Height And Key Facts
Important Considerations
- Leucovorin should only be used under the supervision of a qualified healthcare professional.
- Patients with kidney problems may require dose adjustments.
- Leucovorin is not a substitute for folic acid in pregnant women with nutritional deficiencies.
- Regular monitoring of blood levels and kidney function may be necessary during leucovorin therapy.
Leucovorin is a valuable medication that helps mitigate the toxic effects of certain drugs and plays a crucial role in cancer treatment and folate deficiency management. Understanding its uses, dosage, and potential side effects is essential for both patients and healthcare providers to ensure safe and effective use.
