Levofolene

Levoleucovorin, the active ingredient in Levofolene, is a folate analog presented as a sterile injectable solution for intramuscular and intravenous use. It provides reduced folate to patients experiencing methotrexate toxicity, folate deficiency, or requiring folate supplementation during cancer chemotherapy.

GNH USA supplies Levofolene as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres and pharmacies worldwide. The company adheres to EU quality standards and offers reliable global distribution.

Levoleucovorin is used in clinical situations that involve folate pathway disruption, such as methotrexate toxicity and folate deficiency.

- Methotrexate toxicity rescue: restores folate‑dependent DNA synthesis to reduce toxic effects. - Folate deficiency: supplies reduced folate to correct deficiency states. - Adjunct in cancer chemotherapy: supports patients receiving antifolate agents by mitigating folate depletion.

Levofolene may be associated with a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Nausea: mild to moderate feeling of stomach upset. - Headache: transient cranial discomfort. - Injection site pain: localized soreness or erythema. - Mild fatigue: temporary decrease in energy levels.

Serious or Rare Side Effects: - Anaphylactic reaction: severe hypersensitivity requiring immediate medical attention. - Acute renal failure: sudden loss of kidney function, especially in patients with pre‑existing renal impairment. - Severe hepatic toxicity: marked elevation of liver enzymes indicating liver injury.

Before using Levofolene, healthcare professionals should consider several precautionary measures to ensure safe administration.

- Assess renal function: adjust use in patients with impaired kidney function. - Monitor hepatic status: watch for liver enzyme elevations during therapy. - Review concomitant antifolate drugs: avoid overlapping toxicities. - Evaluate for hypersensitivity: discontinue if signs of allergic reaction appear. - Pregnancy and lactation: use only if benefits outweigh potential risks, as safety data are limited. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Levofolene can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - High‑dose methotrexate: concurrent use without rescue may increase toxicity. - Trimethoprim‑sulfamethoxazole: can potentiate folate deficiency. - Anticonvulsants (e.g., phenytoin, carbamazepine): may reduce folate levels, diminishing rescue effect.

Moderate Interactions (Monitor Closely): - NSAIDs: may affect renal clearance of folate analogs. - Proton pump inhibitors: possible reduction in absorption of oral folate forms. - Vitamin B12 supplements: monitor for altered methylation cycles.
