Fedolen

Calcium folinate, the active ingredient in Fedolen, is a folate analog presented as a 5mg/10ml injection for intravenous use. It is primarily used to counteract the effects of folic acid antagonists and support cellular function and DNA synthesis. GNH USA supplies Fedolen as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals and oncology centers worldwide.

Fedolen is essential in managing methotrexate toxicity and folate deficiency, ensuring effective rescue therapy in critical care settings. Its formulation adheres to stringent quality standards, making it a reliable choice for healthcare professionals.

Fedolen acts on the folate pathway, crucial for cellular function and DNA synthesis. It is used to:

- Methotrexate toxicity rescue: Mitigates the toxic effects of methotrexate by providing a reduced form of folic acid. - Folate deficiency: Treats folate deficiency when oral administration is not feasible, such as in cases of malabsorption or parenteral nutrition. - Combination therapy: Enhances the effectiveness of 5-fluorouracil in cancer treatment by stabilizing its complex with thymidylate synthase.

Fedolen may cause several side effects, ranging from common to serious. Common Side Effects: - Nausea and vomiting - Diarrhea - Stomatitis (inflammation of the mouth) - Rash - Allergic reactions

Serious or Rare Side Effects: - Severe allergic reactions, including anaphylaxis - Increased ammonia levels in the blood - Bone marrow suppression - Severe diarrhea leading to dehydration - Skin reactions such as hand-foot syndrome

Fedolen should be used with caution and under medical supervision. Precautions include: - Allergies: Avoid use in patients with known hypersensitivity to calcium folinate or folic acid. - Renal impairment: Monitor closely in patients with kidney dysfunction. - Pregnancy: Use only if clearly needed, as safety during pregnancy is not established. - Breastfeeding: Consult a healthcare provider before use. - Store below 25°C: Keep in the original pack, protect from moisture.

Fedolen may interact with other medications, requiring careful monitoring. Major Interactions (Avoid): - Antifolate drugs: Avoid concurrent use with methotrexate without proper rescue therapy. - Fluorouracil: Adjust dosing when used in combination to prevent excessive toxicity.

Moderate Interactions (Monitor Closely): - Phenobarbital: May reduce the effectiveness of calcium folinate. - Phenytoin: Monitor for altered drug levels when used together. - Trimethoprim: May require dosage adjustments to avoid folate deficiency.
