Methofill Sd

Methotrexate, the active ingredient in Methofill Sd, is an antimetabolite (folate antagonist) presented as a subcutaneous injection for subcutaneous use. It is employed to treat rheumatoid arthritis, psoriasis, psoriatic arthritis, acute lymphoblastic leukemia and gestational trophoblastic disease in appropriate patients.

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

Methofill Sd (methotrexate) is used across several disease families, primarily autoimmune and malignant disorders.

- Rheumatoid arthritis: reduces joint inflammation and slows structural damage. - Psoriasis: decreases skin plaque formation and severity. - Psoriatic arthritis: improves joint symptoms and skin lesions. - Acute lymphoblastic leukemia: interferes with malignant cell proliferation. - Gestational trophoblastic disease: promotes resolution of abnormal trophoblastic tissue.

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

Common Side Effects: - Nausea or vomiting - Fatigue or malaise - Mouth sores (stomatitis) - Mild liver enzyme elevation - Low white blood cell count (leukopenia) - Skin rash or itching

Serious or Rare Side Effects: - Severe liver toxicity or fibrosis - Pulmonary fibrosis or interstitial pneumonitis - Renal impairment or failure - Significant bone marrow suppression leading to anemia - Life‑threatening infections due to immunosuppression - Rare hypersensitivity reactions including anaphylaxis

Before initiating therapy, clinicians should evaluate baseline organ function and contraindications.

- Pregnancy: contraindicated; teratogenic risk is high. - Breastfeeding: avoid use; drug is excreted in milk. - Renal function: adjust dose or avoid if severe impairment. - Hepatic function: monitor liver enzymes regularly. - Immunosuppression: monitor for signs of infection. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Methotrexate interacts with several medicines that can alter its efficacy or toxicity.

Major Interactions (Avoid): - Non‑steroidal anti‑inflammatory drugs (NSAIDs): increase methotrexate toxicity. - Proton pump inhibitors (e.g., omeprazole): may raise serum levels. - Trimethoprim‑sulfamethoxazole: enhances bone marrow suppression.

Moderate Interactions (Monitor Closely): - Azathioprine or mycophenolate: additive immunosuppression. - Live vaccines: risk of infection due to immunosuppression. - Phenytoin or carbamazepine: may reduce methotrexate effectiveness.
