Methotrexaat Teva

Methotrexate, the active ingredient in Methotrexaat Teva, is an antimetabolite presented as a sterile injectable solution for epidural, intra‑articular and intramuscular use. It is employed to treat autoimmune disorders, certain cancers and ectopic pregnancy in adult patients. GNH USA supplies Methotrexaat Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Methotrexate is a folate antagonist used across several disease families, particularly inflammatory and malignant conditions. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: diminishes skin plaque formation and severity. - Acute lymphoblastic leukemia: interferes with malignant cell proliferation. - Non‑Hodgkin lymphoma: impedes growth of lymphoma cells. - Ectopic pregnancy: terminates trophoblastic tissue to avoid surgical intervention.

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

Common Side Effects: - Nausea and vomiting. - Fatigue or malaise. - Oral mucositis (mouth sores). - Transient elevation of liver enzymes. - Mild hair thinning. - Decreased white blood cell count.

Serious or Rare Side Effects: - Severe hepatotoxicity or liver fibrosis. - Pulmonary fibrosis or interstitial pneumonitis. - Life‑threatening bone marrow suppression. - Acute kidney injury. - Severe cutaneous reactions such as Stevens‑Johnson syndrome. - Opportunistic infections due to immunosuppression.

Methotrexate requires careful monitoring and specific safety measures. - Monitor liver function: perform baseline and periodic liver enzyme tests. - Assess renal function: adjust dosing or avoid use if renal impairment is present. - Check complete blood counts: watch for cytopenias and intervene promptly. - Avoid use in pregnancy unless absolutely necessary: teratogenic risk is high. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

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

Major Interactions (Avoid): - NSAIDs: increase risk of renal toxicity. - Trimethoprim‑sulfamethoxazole: additive bone‑marrow suppression. - Live vaccines: heightened risk of infection. - Antacids containing calcium or aluminum: reduce methotrexate absorption.

Moderate Interactions (Monitor Closely): - Azathioprine: combined immunosuppression may increase infection risk. - Phenytoin: may lower methotrexate plasma levels. - Alcohol: can exacerbate hepatotoxicity.
