About Methotrexate
Methotrexate is a type of chemotherapy. It works by slowing or stopping the growth of cells. This medicine may be given in the clinic, hospital, or at home. The schedule and dose depends on the type of cancer, child's age, and method of administration.
If children receive high doses of methotrexate, they may also be given extra IV fluids and a medicine called leucovorin to reduce side effects.
Patients will have regular blood draws to check blood counts, the amount of methotrexate in the blood (if very large doses are given), and monitor liver and kidney function. Methotrexate dose changes may occur based on levels in the blood.
Possible Late Effects
- Some patients may experience long-term or late effects of treatment that may continue or develop months or years after treatment ends. Possible late effects due to methotrexate include:
- Kidney problems
- Liver problems
- Cognitive problems
Possible Side Effects
- Nausea and vomiting
- Sores around the mouth, lips, or anus
- Sun sensitivity

- Not all patients who take methotrexate will experience these side effects. Common side effects are in bold, but there may be others. Please report all suspected side effects to your doctor or pharmacist.
Tips for Families
- Be sure to discuss these and other recommendations with your doctor or pharmacist.
- While taking methotrexate, patients should not take multivitamins or other supplements containing folic acid, non-steroidal anti-inflammatory drugs (NSAIDS), or proton pump inhibitors (such as omeprazole) unless recommended by a doctor.
