Methotrexate is a folate antagonist used in several disease‑modifying and oncologic indications.

- Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: improves skin lesions and reduces plaque formation. - Acute lymphoblastic leukemia: interferes with malignant cell proliferation. - Non‑Hodgkin lymphoma: contributes to tumor control as part of combination therapy.

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

Common Side Effects: - Nausea or vomiting: gastrointestinal upset. - Fatigue: persistent tiredness. - Mild liver enzyme elevation: transient increase in ALT/AST.

Serious or Rare Side Effects: - Severe liver toxicity: risk of hepatitis or fibrosis. - Pulmonary fibrosis: interstitial lung disease. - Bone marrow suppression: pancytopenia leading to infection or bleeding.

Methotrexate requires careful monitoring and specific safety measures.

- Pregnancy: contraindicated; classified Category X due to teratogenic risk. - Breastfeeding: not recommended; drug is excreted in milk. - Renal function: assess before use; dose adjustment may be needed. - Liver function: monitor enzymes regularly during therapy. - Blood monitoring: perform complete blood count before and during treatment. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Methotrexate interacts with several medicines; some combinations should be avoided while others need close observation.

Major Interactions (Avoid): - NSAIDs (e.g., ibuprofen): increase methotrexate toxicity. - Penicillins (e.g., ampicillin): raise serum methotrexate levels. - Live vaccines: heightened risk of infection.

Moderate Interactions (Monitor Closely): - Azathioprine: may enhance immunosuppression; monitor blood counts. - Warfarin: methotrexate can potentiate anticoagulant effect; monitor INR.
