Methotrexate is used in several autoimmune and oncologic disease pathways to modify disease activity and improve clinical outcomes.

Rheumatoid arthritis: reduces joint inflammation and slows structural damage. Psoriasis: decreases skin lesion severity and plaque formation. Acute lymphoblastic leukemia: interferes with malignant cell proliferation to achieve remission. Non‑Hodgkin lymphoma: suppresses tumor growth and enhances response to combination therapy. Gestational trophoblastic disease: promotes resolution of trophoblastic tissue and normalizes hCG levels.

Methotrexate can cause a range of adverse reactions, varying from mild to severe, that require monitoring during therapy.

Common Side Effects: - Nausea: mild to moderate gastrointestinal upset. - Fatigue: persistent tiredness. - Mouth ulcers: painful oral lesions. - Elevated liver enzymes: transient hepatic enzyme rise. - Diarrhea: loose stools that may affect hydration. - Skin rash: mild erythematous eruptions.

Serious or Rare Side Effects: - Bone marrow suppression: pancytopenia leading to infection risk. - Pulmonary toxicity: interstitial pneumonitis or fibrosis. - Severe hepatotoxicity: progressive liver fibrosis or cirrhosis. - Renal toxicity: impaired renal function or acute kidney injury. - Severe cutaneous adverse reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before initiating therapy and throughout treatment, careful monitoring and patient education are essential.

Monitor blood counts: perform regular CBC to detect cytopenias. Assess liver function: schedule periodic LFTs for hepatotoxicity. Evaluate renal function: check serum creatinine before and during therapy. Avoid use in pregnancy: contraindicated due to teratogenic risk. Counsel about infection risk: advise patients to report fever or signs of infection promptly. Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Methotrexate has several drug interactions that may require avoidance or close monitoring.

Major Interactions (Avoid): - NSAIDs: increase methotrexate toxicity. - Live vaccines: risk of severe infection. - High‑dose penicillins: reduce renal clearance.

Moderate Interactions (Monitor Closely): - Proton pump inhibitors: may raise serum methotrexate levels. - Azathioprine: additive immunosuppression. - Alcohol: enhances hepatic toxicity.
