What is the most important information I should know about methotrexate?
Methotrexate is usually taken once or twice per week and not every day. You must use the correct dose of methotrexate for your condition. Some people have died after taking methotrexate every day by accident.
Do not use methotrexate to treat psoriasis or rheumatoid arthritis if you have liver disease (especially if caused by alcoholism), or a blood cell or bone marrow disorder
