Methotrexate works by slowing down the growth of cells that cause inflammation and damage in the body. Folic acid is given to help prevent certain side effects of methotrexate, such as low red blood cell count (anemia).

Store methotrexate tablets at room temperature, away from moisture and heat. Keep methotrexate solution refrigerated. Do not freeze.

The dosage of methotrexate and folic acid varies depending on the condition being treated and the individual's response.

Methotrexate is typically taken once a week, usually on the same day each week.
