Are there any special things I should do while on this medicine?

Methotrexate can decrease the number of white blood cells in your body, cells that usually help you fight infections. It can also decrease the number of cells in your blood that help your blood clot (platelets) and the number of red blood cells, cells that carry oxygen to your tissues. Without enough red blood cells, the tissues get less oxygen and you could become fatigued. Ask your doctor, nurse, or pharmacist how to reduce your risk of infection, bleeding, or fatigue.

Tell your doctor, nurse, or pharmacist if you have ever had liver problems, including cirrhosis, hepatitis, or jaundice. Methotrexate causes liver damage in a small number of patients and should be used very carefully in patients who have had liver disease.

Do not drink alcohol (i.e., beer, wine, hard liquor) or drink less alcohol while you take methotrexate. Alcohol increases the effects of methotrexate on the liver.

Avoid getting sunburned for several days before starting therapy with methotrexate. If you get sunburned during this time, the sunburn may return or worsen when you start this medicine.

Avoid getting sunburned while taking methotrexate. Your skin may be more sensitive to sunlight and you may sunburn more easily.

Check with your doctor, nurse, or pharmacist before taking any other medicine. Methotrexate causes serious side effects when combined with many medications. Prescription, nonprescription, or over-the-counter medicines which may cause problems include medicines for fever, pain, headache, or arthritis.

Tell your doctor, nurse, or pharmacist right away if you vomit within one hour after taking methotrexate by mouth.

What if I miss a dose?
