What are the side effects/risks?
- Increased risk of infection
- Because Methotrexate acts by modulating the activity of the immune system, the resistance to infections is slightly decreased.
- Methotrexate is often taken at night and over the weekend during off times from work to help offset these potential side effects. Anti-nausea medications can be taken prior to your dose.
- Liver toxicity
- Methotrexate can cause liver injury. It is necessary to monitor the liver function
regularly with blood tests. Folic acid deficiency
- Because this medication competes with the body for folic acid, it is important to take a folic acid supplement daily. This is an over the counter supplement and should be taken every day except on the day of your methotrexate dose.
- Interstitial Pneumonitis
- Methotrexate can cause damage to the lungs. Call the doctor if you develop a dry cough, fever, or shortness of breath.
