Your doctor has ordered the drug methotrexate to help treat your illness. The drug can be taken by mouth in tablet form.

This medication is used to treat:

  • psoriasis
  • rheumatoid arthritis
  • trophoblastic neoplasms
  • leukemias

Precautions

Before taking methotrexate,

  • tell your doctor and pharmacist if you are allergic to methotrexate or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially those listed in the IMPORTANT WARNING section, azathioprine (Imuran), oral acne medications such as isotretinoin (Accutane) and tretinoin (Vesanoid), oral diabetes medications, phenytoin (Dilantin), probenecid (Benemid), sulfa drugs (Bactrim, Septra), sulfasalazine (Azulfidine), tetracycline (Achromycin V, Sumycin), and vitamins.
  • in addition to the conditions listed in the IMPORTANT WARNING section, tell your doctor if you have or have ever had liver disease, ulcers, problems with your immune system, intestinal disease, or cancer.
  • you should know that methotrexate may interfere with the normal menstrual cycle (period) in women and may stop sperm production in men.
