What is methotrexate (Rheumatrex)?
Methotrexate interferes with the growth of certain cells of the body, especially cells that reproduce quickly, such as cancer cells, bone marrow cells, and skin cells.

Methotrexate is usually given after other medications have been tried without successful treatment of symptoms.

What is the most important information I should know about methotrexate (Rheumatrex)?
You must use the correct dose of methotrexate for your condition. Methotrexate is usually taken once or twice per week and not every day. Follow the directions on your prescription label. Some people have died after taking methotrexate every day by accident. Ask your doctor if you have any questions about your dose of methotrexate or how often to take it.
Methotrexate can cause serious or life-threatening side effects on your liver, lungs, kidneys, and bone marrow (immune system). Do not take this medication in larger amounts, or take it for longer than prescribed. Follow the directions on your prescription label.
Do not use methotrexate to treat psoriasis or rheumatoid arthritis if you have liver disease (especially if caused by alcoholism), a blood cell or bone marrow disorder, or if you are breast-feeding a baby.
This medication can cause birth defects in an unborn baby. Do not use methotrexate to treat psoriasis or rheumatoid arthritis if you are pregnant. Use an effective form of birth control, whether you are a man or a woman. Tell your doctor if you or your sexual partner become pregnant during treatment.
To be sure this medication is not causing harmful effects, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled appointments.
There are many other medicines that can interact with methotrexate. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor. Keep a list with you of all the medicines you use and show this list to any doctor or other healthcare provider who treats you.
