What should I know during treatment with DBL Fluorouracil Injection BP?

Things you should do

Keep all of your doctor’s appointments so your progress can be checked.
Your doctor may want to do blood and other tests from time to time to check on your progress and detect any unwanted side effects.
Keep follow up appointments with your doctor.
It is important to have your follow-up doses of fluorouracil at the appropriate times to get the best effects from your treatments.
Take precautions to reduce your risk of bleeding or infection
This medicine can lower the number of white blood cells and platelets in your blood. This means that you have an increased chance of getting an infection or bleeding. The following precautions should be taken to reduce your risk of infection or bleeding:
Avoid people who have infections. Check with your doctor immediately if you think you may be getting an infection, or if you get a fever, chills, cough, hoarse throat, lower back or side pain or find it painful or difficult to urinate.
Be careful when using a toothbrush, toothpick or dental floss. Your doctor, dentist, nurse or pharmacist may recommend other ways to clean your teeth and gums. Check with your doctor before having any dental work.
Be careful not to cut yourself when you are using sharp objects such as a razor or nail cutters.
Avoid contact sports or other situations where you may bruise or get injured.
Take precautions to protecting other people while receiving treatment with DBL Fluorouracil Injection BP
Your body breaks down fluorouracil and uses it to fight cancer. The breakdown products may be excreted in body fluids and waste, including blood, urine, faeces, vomit and semen.
In general, precautions to protect other people should be taken while you are receiving chemotherapy and for one week after the treatment period by:
Flushing the toilet twice to dispose of any body fluids and waste
Wearing gloves to clean any spill of body fluid or waste. Use paper towels or old rags, a strong solution of non-bleaching detergent and large amounts of water to mop up the spill. Discard the towels or rags into a separate waste bag and dispose of fluids in the toilet
Washing linen or clothing that is heavily contaminated by body fluids or waste separately from other items. Use a strong solution of non-bleaching detergent and large amounts of water
Placing soiled disposable nappies and other pads in a plastic bag, seal and dispose into the garbage
For sexual intercourse, use a barrier method such as a condom.

Call your doctor immediately if you become pregnant while you are being given fluorouracil.

Remind any doctor, dentist, nurse or pharmacist you visit that you are being given DBL Fluorouracil Injection BP.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how DBL Fluorouracil Injection BP affects you.
DBL Fluorouracil Injection BP may cause dizziness, tiredness or confusion in some people. If you have any of these symptoms, do not drive, operate machinery, or do anything else that could be dangerous.
