Methotrexate (MTX) is considered a disease-modifying anti-rheumatic drug (DMARD), which means that it slows the progression of rheumatoid arthritis (RA).
Although no one knows exactly how MTX works, one theory is that it interferes with the process that causes inflammation and joint damage in the body.
MTX is also thought to change how the body uses folic acid, a vitamin that is needed for cell growth.
When methotrexate is taken as an injection, the body absorbs it in a different way than when it is taken orally.
Methotrexate can be used alone or in combination with other treatments for RA.
