Methotrexate tablets are used to treat certain types of cancer, such as leukemia and lymphoma, as well as autoimmune diseases such as rheumatoid arthritis and psoriasis. They work by inhibiting certain enzymes that affect cell growth, preventing cancer cells from dividing and reducing the activity of the immune system. Methotrexate is given in varying doses depending on the condition, either orally or by injection. It must be under close medical supervision to determine the dose and monitor the response to treatment. Common side effects include nausea, mouth ulcers, and low blood cells. It may also affect the liver and kidneys, so regular monitoring is required during use.
Methotrexate is a powerful and important drug in complex treatment plans for cancer and immune diseases.
