Methotrexate Teva

Methotrexate, the active ingredient in Methotrexate Teva, is an antimetabolite (folate antagonist) presented as a sterile solution for epidural, intrabursal and intracoronary use. It treats rheumatoid arthritis, psoriasis, acute lymphoblastic leukemia and non‑Hodgkin lymphoma in appropriate patients.

GNH USA supplies Methotrexate Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres and pharmacies worldwide.

Methotrexate is used across several disease families, primarily as an immunosuppressant and antineoplastic agent. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: decreases skin cell proliferation and improves plaque lesions. - Acute lymphoblastic leukemia: interferes with malignant cell replication to achieve remission. - Non‑Hodgkin lymphoma: limits tumor growth by inhibiting DNA synthesis.

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

Common Side Effects: - Nausea and vomiting. - Fatigue or general weakness. - Oral mucosal ulcers or sore mouth. - Mild elevation of liver enzymes. - Transient rash or itching. - Mild decrease in blood cell counts.

Serious or Rare Side Effects: - Severe hepatotoxicity or liver fibrosis. - Pulmonary fibrosis or interstitial pneumonitis. - Life‑threatening bone marrow suppression. - Acute renal failure. - Severe infections due to immunosuppression. - Anaphylactic or severe allergic reactions.

Before initiating therapy, several safety considerations should be addressed. - Liver monitoring: perform baseline and periodic liver function tests. - Hematologic monitoring: check complete blood counts regularly. - Pregnancy avoidance: do not use in pregnant or nursing women unless clearly indicated. - Renal assessment: evaluate kidney function and adjust dosing if needed. - Drug review: assess concomitant medications for potential interactions. - Store at ambient temperature: keep in original container, protect from moisture and light.

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

Major Interactions (Avoid): - Non‑steroidal anti‑inflammatory drugs (NSAIDs): increase toxicity risk. - Penicillins: may enhance hematologic suppression. - Sulfonamide antibiotics: can potentiate bone marrow effects. - Live vaccines: risk of severe infection. - Alcohol: exacerbates liver injury.

Moderate Interactions (Monitor Closely): - Proton pump inhibitors: may affect absorption. - Trimethoprim‑sulfamethoxazole: increase myelosuppression. - Azathioprine: additive immunosuppression. - Leflunomide: heightened hepatotoxicity. - Warfarin: potential alteration of anticoagulant effect.
