What is Methotrexate used for?
Methotrexate is used in autoimmune and oncologic conditions that involve rapid cell proliferation.
Rheumatoid arthritis: reduces joint inflammation and slows disease progression. Psoriasis: decreases skin lesion severity and plaque formation. Acute lymphoblastic leukemia: inhibits malignant lymphoblast proliferation. Non‑Hodgkin lymphoma: suppresses tumor growth. Ectopic pregnancy: terminates trophoblastic tissue.
What are the side effects of Methotrexate?
Methotrexate may cause a range of adverse reactions.
Common Side Effects: - Nausea or vomiting. - Fatigue or malaise. - Headache. - Mild elevation of liver enzymes. - Stomatitis or mouth ulcers. - Increased susceptibility to mild infections.
Serious or Rare Side Effects: - Severe liver toxicity or hepatitis. - Bone marrow suppression leading to pancytopenia. - Pulmonary fibrosis or interstitial pneumonitis. - Life‑threatening infections. - Acute renal failure. - Anaphylactic or severe hypersensitivity reactions.
What precautions apply to Methotrexate?
Patients receiving Methotrexate should be monitored closely for safety.
Monitor liver function: perform regular hepatic enzyme tests. Monitor blood counts: watch for cytopenias and anemia. Avoid use in pregnancy: drug is teratogenic (Category X). Use caution in renal impairment: adjust dose as needed. Counsel on infection risk: advise prompt reporting of fever or signs of infection.
