How it is given

How much is given

Your doctor will decide what dose you will receive. This depends on several factors including your height and weight, and whether or not other chemotherapy medicines are also being given.

Irinotecan may be given alone or in combination with other medicines to treat cancer.

Several treatment courses of irinotecan may be needed, depending on your response to treatment.

Additional treatment may not be repeated until your blood cell numbers return to acceptable levels and any uncontrolled effects have been controlled.

Ask your doctor if you want to know more about the dose of irinotecan you will be receiving.

How it is given

DBL™ Irinotecan Injection Concentrate is given as a slow injection into a vein. It must only be given by a nurse or doctor.

If you receive too much (overdose)

As Irinotecan Injection Concentrate is given to you under the supervision of your doctor, it is very unlikely that you will receive an overdose. However if you experience severe side effects tell your doctor immediately or call the Poison Information Centre (in Australia call 13 11 26, or New Zealand call 0800 764 766), or go to Accident and Emergency at your nearest hospital. You may need medical attention.

Symptoms of an overdose may include the side effects listed below in the 'Side effects' section, but are usually of a more severe nature.

Ask your doctor or pharmacist if you have any concerns.

While you are being given it

Things you must do

Tell your doctor as soon as possible if diarrhoea occurs. Diarrhoea is a common side effect of irinotecan. Your doctor will prescribe a medicine for you to take in case you get diarrhoea after treatment. You should start taking this medicine when you first have poorly formed or loose stools or bowel movements more frequently than you would normally expect. If untreated, severe diarrhoea can be life-threatening.

You must use a reliable method of contraception (birth control) while being treated with irinotecan. However, if you become pregnant while you are being treated with this medicine, tell your doctor immediately.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are being given irinotecan.

Tell any other doctors, dentists, and pharmacists who treat you that you are being given this medicine.

If you are going to have surgery, tell the surgeon or anaesthetist that you are being given this medicine. It may affect other medicines used during surgery.

You must use a reliable method of contraception (birth control) while being treated with irinotecan. However, if you become pregnant while you are being treated with this medicine, tell your doctor immediately.

Keep all of your doctor’s appointments and follow up appointments so that:

  • your progress can be checked
  • you have your follow up doses of irinotecan.

Your doctor may want to check your blood pressure and do some blood and other tests from time to time to check on your progress and to detect any unwanted side effects. It is also important to have your follow-up doses of irinotecan at the appropriate times to get the best effects from your treatments.

Things you must not do

Do not take any laxatives without checking with your doctor. Diarrhoea is a common side effect of irinotecan. Taking laxatives, even if you are constipated, may cause or worsen diarrhoea.

Things to be careful of

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 protect other people while you are receiving chemotherapy and for one week after the treatment period. Your body breaks down irinotecan and uses it to fight cancer. The breakdown products may be excreted in body fluids and waste, including blood, urine, faeces, vomit and semen.

Take the following precautions:

  • 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
  • using a barrier method such as a condom, for sexual intercourse.

Make sure you know what to do if you experience nausea, vomiting or diarrhoea.

You may feel nauseous, and have vomiting, diarrhoea, and/or stomach cramping, during or after treatment with irinotecan. It is likely that your doctor will give you one or more medicines to help manage these side effects.

Be careful driving or operating machinery until you know how irinotecan affects you. This medicine may cause dizziness or light-headedness in some people. If you have any of these symptoms, do not drive, operate machinery, or do anything else that could be dangerous.

Be careful when drinking alcohol while you are taking this medicine. If you drink alcohol, dizziness or light-headedness, and diarrhoea may be worse.

Side effects

Tell your doctor or nurse as soon as possible if you do not feel well or if you experience severe side effects while you are being treated with irinotecan. Like other medicines used to treat cancer, irinotecan may have unwanted side effects, some of which may be serious. You may need medical attention if you get some of the side effects.

If you are over 65 years of age you may have an increased chance of getting side effects.

Do not be alarmed by the following lists of side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

  • indigestion
  • difficulty sleeping

The above list includes side effects which are usually mild or short-lived.

Tell your doctor or nurse as soon as possible if you notice diarrhoea. If untreated, severe diarrhoea can be life threatening. Your doctor will probably prescribe loperamide (a medicine used to treat diarrhoea) for you to take in case you get diarrhoea after treatment. You should start taking loperamide when you first have poorly formed or loose stools, or more frequent bowel movements than you would normally expect.

Tell your doctor or nurse as soon as possible if you notice any of the following:

  • vomiting
  • abdominal cramping/pain
  • runny nose or eyes, increased salivation, sweating or flushing
  • tiredness, headaches, being short of breath when exercising, dizziness and looking pale

  • swelling and redness along a vein
  • fluid retention that results in swelling.

The above list includes serious side effects, which may require medical attention.

Tell your doctor or nurse immediately, or go to Accident and Emergency at your nearest hospital, if you notice any of the following:

  • inability to control diarrhoea within 24 hours after taking loperamide
  • any signs of infection such as fever, chills, sore throat or cough, low back or side pain, painful or difficult urination
  • symptoms of dehydration, such as faintness, light-headedness or dizziness, increased thirst, wrinkling of the skin
  • inability to drink due to nausea or vomiting
  • signs of an allergic reaction, such as shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin
  • unusual bleeding or bruising (such as bloody or black stools, blood in urine)
  • yellowing of the skin and/or eyes (these may be symptoms of a type of liver disease called jaundice)
  • chest pain.

The above list includes very serious side effects. You may need urgent medical attention or hospitalisation.

Tell your doctor, nurse or pharmacist if you notice anything that is making you feel unwell. Other side effects not listed above may occur in some people. Some of these side effects can only be found when your doctor does tests from time to time to check your progress.

The benefits and side effects of irinotecan may take some time to occur. Therefore even after you have finished treatment with irinotecan, you should tell your doctor if you notice anything that is making you feel unwell.
