Methofill

Methotrexate, the active ingredient in Methofill, is an antimetabolite (folate antagonist) presented as a subcutaneous formulation for injection use. It treats autoimmune conditions such as rheumatoid arthritis and psoriasis, and is also employed in oncology for certain leukemias and solid tumours.

GNH USA supplies Methofill as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres and pharmacies worldwide.

Methofill, a folate antagonist, is indicated for several autoimmune and oncologic disease groups. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: improves skin lesions and decreases scaling. - Acute lymphoblastic leukemia: induces remission by inhibiting malignant cell proliferation. - Gestational trophoblastic disease: promotes resolution of trophoblastic tissue. - Osteosarcoma: used as part of chemotherapy regimens to limit tumor growth.

Methofill may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nausea and vomiting - Fatigue or malaise - Oral mucosal ulceration (mouth sores) - Transient elevation of liver enzymes - Mild rash or pruritus - Low white blood cell count (leukopenia)

Serious or Rare Side Effects: - Severe hepatic toxicity or fibrosis - Pulmonary fibrosis or interstitial pneumonitis - Life‑threatening infections due to bone‑marrow suppression - Acute renal failure - Secondary malignancies - Severe bone‑marrow failure (aplastic anemia)

Before initiating therapy, clinicians should assess baseline organ function and counsel patients on safety measures. - Monitor blood counts: perform regular complete blood count tests. - Monitor liver function: check hepatic enzymes periodically. - Avoid use in pregnancy: methotrexate is contraindicated and requires effective contraception. - Assess renal function: adjust dosing in patients with impaired clearance. - Use caution in patients with pre‑existing lung disease. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Methofill can interact with several medicines, requiring careful management.

Major Interactions (Avoid): - Non‑steroidal anti‑inflammatory drugs (NSAIDs): increase risk of toxicity. - Live vaccines: may cause uncontrolled infection. - Other folate antagonists (e.g., pemetrexed): additive bone‑marrow suppression.

Moderate Interactions (Monitor Closely): - Azathioprine: enhanced immunosuppression. - Penicillins: may affect renal clearance of methotrexate.
