This medicine will be given to you by your doctor or by a nurse under the supervision of your doctor. It will be diluted and given to you as a slow injection into a vein over a period of 90 minutes.

Your doctor will decide how much you will be given. Ask your doctor if you want to know more about the dose you will be receiving.

Irinotecan Sandoz may be given alone or with other medicines used to treat cancer.

Treatment with this medicine may be repeated more than once, depending on how your body responds to the treatment.

Treatment may not be repeated until your blood cell numbers return to an acceptable level. Treatment should be interrupted if you get severe diarrhoea or any other intolerable side effects.

If you receive too much (overdose)

An overdose is unlikely because Irinotecan Sandoz will be given to you under the supervision of your doctor. The possible effects of having too much irinotecan are the same as those listed in the ‘Side effects’ section of this leaflet.

Things you must do

Keep all of your doctor’s appointments, so that your progress can be assessed and any problems can be discussed with your doctor.

If you are about to start taking a new medicine, tell your doctor and pharmacist that you are being treated with Irinotecan Sandoz.

If you are going to have surgery, tell your surgeon or the anaesthetist that you are being given this medicine.

If you are going to get vaccinated, tell your doctor, nurse or pharmacist that you are being treated with Irinotecan Sandoz.

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

Diarrhoea is a common side effect of irinotecan. Tell your doctor as soon as possible if you have diarrhoea. Your doctor may need to prescribe a medicine to treat the diarrhoea. If left untreated, severe diarrhoea can be life threatening. You must tell your doctor if you cannot get diarrhoea under control within 24 hours after taking an antidiarrhoeal. Also tell your doctor if you develop a fever in addition to the diarrhoea.

This medicine can increase the chance of you getting an infection and can increase the chance of bleeding. So the following precautions need to be taken:

  • Avoid people who have infections and tell your doctor if you think you may be getting an infection. Signs of an infection include fever, chills, coughing, a hoarse throat, mouth ulcers, lower back pain, side pain or painful urination.
  • Be careful when using a toothbrush, toothpick or dental floss. Tell your doctor before having any dental work.
  • Be careful not to cut yourself when using sharp objects (such as a razor, or nail clippers) and avoid situations where you may bruise yourself or get injured.
  • Tell your doctor if you have severe stomach cramps. You may need to be treated with medication.

Things to be careful of

Your body breaks down irinotecan and the breakdown products may be excreted in body fluids and waste, including blood, urine, faeces vomitus and semen. Other people need to be protected from these body fluids and waste while you are being treated with irinotecan.

The following precautions should be taken while you are receiving chemotherapy and for 1 week after the treatment period:

  • Use gloves and disposable towels when cleaning or disposing of any body fluids and waste.
  • Wash any clothing or linen that is heavily contaminated by body fluids separately in a strong solution of detergent.
  • Use a condom for sexual intercourse.

Be careful driving or operating machinery until you know how this medicine affects you. It may cause dizziness or light-headedness in some people.

Be careful when drinking alcohol while you are being treated with this medicine. Light-headedness, dizziness and diarrhoea may become worse.

Because of the risk of diarrhoea, do not take laxatives during treatment course with irinotecan. Talk to your doctor if you need more information regarding this.

All medicines can have unwanted effects. Sometimes they are serious, most of the time they are not. Do not be alarmed by this list of possible side effects. You may not experience any of them. Fatal outcomes have occurred, which in some cases, may have been related to treatment.

Tell your doctor or nurse as soon as possible if you notice diarrhoea. Severe diarrhoea can be life threatening if left untreated.

These may be serious side effects that may need urgent medical attention.

If any of the following happen, stop treatment and tell your doctor or nurse immediately, or go to Accident and Emergency at your nearest hospital:

  • The inability to control diarrhoea within 24 hours after taking loperamide.
  • Symptoms of dehydration which include faintness or dizziness, light-headedness, increase in thirst and wrinkling skin.
  • An inability to drink due to nausea or vomiting.
  • Signs of an infection such as chills, fever, sore throat, cough, lower back pain, pain or difficulty in urinating.
  • Signs of an allergic reaction eg swelling of the face, lips, mouth or throat which may cause difficulty in swallowing or breathing.
  • Unusual bleeding (such as bloody or black stools and bloody urine) or bruising.
  • Yellowing of the skin or eyes.
  • Chest pains.
  • Any of the following rare side effects: slowed heart beat, fainting, blackouts, blood clots, swelling and redness along a vein which is extremely tender when touched.
