PATIENT MEDICATION

Fluorouracil

 

Description

Fluorouracil (also called 5-FU or Adrucil®) is an anticancer medicine. It is a clear to yellow-colored liquid given by vein (IV).

Fluorouracil can pose a health hazard to caregivers. All caregivers should take safety precautions while giving this drug. For 48 hours after this drug is given, the patient’s body fluids can contain the drug. During that 48-hour period, caregivers should follow safety guidelines when handling the patient’s vomit, blood, urine, and bowel movements, including diapers. These guidelines include wearing gloves when cleaning up body fluids. For a complete list of safety precautions, see “Do you know… Protecting caregivers from drug hazards.”

Laboratory testing

An enzyme in the body called dihydropyrimidine dehydrogenase (DPYD) has the ability to break down certain medicines including fluorouracil. A genetic test can be done to determine how well your DPYD breaks down medicines. If your body breaks down this medicine more slowly, you should receive lower doses or avoid fluorouracil. For more information about DPYD and its effect on fluorouracil, talk with your doctor or pharmacist, and see “Do you know… DPYD and Medicines.” For more details, go to stjude.org/pg4kds.

Special instructions

  • If you have nausea or vomiting, tell your doctor. The doctor can order medicine to keep you from feeling sick and throwing up while you are being treated with fluorouracil.
  • This medicine can make you sensitive to the sun. Use a sunscreen lotion and wear clothing to protect your skin from the sun while you are receiving fluorouracil.
  • The staff will take blood samples to check blood counts and to check liver and kidney function while you are treated with fluorouracil.
