Methotrexate tablets are used to treat various types of cancer, such as leukemia and lymphoma, as well as some immune diseases, such as rheumatoid arthritis. They work by inhibiting enzymes that are important in DNA production, which prevents the division of rapidly growing cells, such as cancer cells. Methotrexate is given orally or by injection under the supervision of a specialist doctor. It is necessary to monitor liver, kidney, and blood functions during treatment to avoid complications, which may include nausea, mouth ulcers, and low blood cell counts.
Methotrexate is considered an effective drug that is included in chemotherapy and immunotherapy plans.
