Methotrexate

(meth-oh-TREKS-ate)

Methotrexate is a medicine used to treat certain types of cancer, as well as certain types of psoriasis and rheumatoid disorders.

If you are unsure about why your child is receiving methotrexate, ask your child's doctor.

It is available as a tablet and as an injectable medication that may be given subcutaneously (under the skin), intramuscularly (into the muscle), intravenously (IV), or intrathecally (into the spinal fluid).

  • If your child is taking tablets, take them all at the same time on an empty stomach. Do not spread the dose at different times during the day.
  • Ask your child's doctor before giving any other medications including over-the-counter medications, even pain or cold and flu medications.
  • Have your child drink plenty of fluids while taking this medication in order to stay hydrated.
  • Milk may decrease the amount of methotrexate that gets absorbed into the body. Avoid taking milk with the dose.
  • This drug may increase your child's sensitivity to the sun. Be careful to limit your child's sun exposure and use sunscreen (SPF 15) and wear protective clothing (long sleeves and hats) when outside.
  • Store medication at room temperature away from moisture and sunlight. Do not refrigerate. Do not store in the bathroom.
  • Your child's doctor may want to have your child's blood drawn to monitor for side effects of the drug.
  • Do not use after the expiration date on the bottle / package.
  • If too much medicine is taken by accident, call the Drug and Poison Information Center (DPIC), 513-636-5111 or 1-800-222-1222, or call your child's doctor immediately.
