It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

What MEDITAB IRINOTECAN is used for

MEDITAB IRINOTECAN is used to treat bowel cancer which has spread to other parts of the body.

Cancer which has spread cannot be treated by surgery alone. One of the options in this situation is treatment with an anticancer medicine, known as chemotherapy.

MEDITAB IRINOTECAN may be used once spread of cancer beyond the bowel is first diagnosed. At this time MEDITAB IRINOTECAN will be given in combination with other anticancer medicines. Alternatively, MEDITAB IRINOTECAN is used alone when the cancer has not responded or has returned after initial treatment.

Ask your doctor if you have any questions about why MEDITAB IRINOTECAN has been prescribed for you.

Your doctor may have prescribed it for another purpose.

Use in children

It is not known if MEDITAB IRINOTECAN is safe and effective in the treatment of children.

  • are allergic to irinotecan hydrochloride or any of the ingredients listed at the end of this leaflet

  • are breastfeeding or intend to breastfeed

Before treatment with MEDITAB IRINOTECAN

You should be treated with MEDITAB IRINOTECAN by a doctor who is experienced in treating patients with cancer. Treatment will normally take place in a hospital because of the need for hospital facilities and skilled personnel.

It is likely that your doctor will give you one or more medicines before administering MEDITAB IRINOTECAN, to help stop you vomiting or feeling sick after the treatment.

You will probably also have a blood test.

You should tell your doctor if:

  • you are 65 years of age or older
  • you have or have had liver disease, kidney disease or heart disease
  • you have previously been treated with radiation therapy
  • you have diabetes
  • you have asthma
  • you have constipation
  • you have difficulty urinating
  • you have hereditary fructose intolerance
  • you have Criglar-Naijar syndrome or Gilbert’s syndrome
  • you are going to be vaccinated (have an injection to prevent a certain disease)

If you have not told your doctor about any of the above, tell your doctor before you are given MEDITAB IRINOTECAN.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including:

  • all prescription medicines
  • all medicines, vitamins, herbal supplements or natural therapies that you buy without a prescription from a pharmacy, supermarket, naturopath or health food shop.

Some medicines and MEDITAB IRINOTECAN may interfere with each other. In particular, tell your doctor if you are taking:

  • laxatives (e.g. for constipation)
  • diuretics (medicines which make you pass urine more frequently e.g. for heart disease)
  • any medicine for nausea or diarrhoea
  • dexamethasone (may be used to treat skin diseases, asthma or other allergic disorders)
  • anticonvulsants used to treat seizures
  • St John’s Wort, a herbal medicine used to treat depression
  • ketoconazole used to treat fungal infections.
  • atazanavir, used to treat HIV-1 infection
  • prochlorperazine, used to treat nausea, vomiting and dizziness
  • suxamethonium or other medicines used as an anaesthetic
  • other medicines used to treat cancer.

Ask your doctor or other health care professional if you are not sure about this list of medicines. You may need to take different amounts of your medicines or you may need to use different medicines. Your doctor will advise you.

How MEDITAB IRINOTECAN is given

MEDITAB IRINOTECAN will be given to you by your doctor. It is diluted and given by slow infusion into a vein over a period of 90 minutes.

It is recommended that MEDITAB IRINOTECAN be given in different treatment courses depending on whether MEDITAB IRINOTECAN is given alone or in combination with other anticancer medicines.

Combination Treatment Courses

When MEDITAB IRINOTECAN is given in combination, treatment courses are of 6 weeks duration given either weekly or fortnightly. Rest periods of 1 or 2 weeks are incorporated into the 6 week courses.

Single Treatment Courses

MEDITAB IRINOTECAN may be given either weekly for 4 weeks followed by a 2 week rest period or it may be given once every 3 weeks.

Depending on your response, treatment courses may be repeated more than once.

It is recommended that treatment with MEDITAB IRINOTECAN should be interrupted if you get severe diarrhoea or other intolerable side effects.

Dose

Your doctor will decide the most appropriate dose of MEDITAB IRINOTECAN to be given.

Ask your doctor if you want more information about the dose of MEDITAB IRINOTECAN and the other medicines you will be receiving and how they are given while you are being treated with MEDITAB IRINOTECAN.

After your first treatment course, the dose of MEDITAB IRINOTECAN may be increased by your doctor if you have not had too many side effects.

Your doctor will lower the dose or stop treatment if you have serious side effects, particularly diarrhoea or changes appearing in your blood tests.

In case of overdose

Overdose is unlikely as treatment will be given in hospital under the supervision of a doctor. The possible effects of overdose are the same as those listed below under Side effects.

Tell your doctor immediately if you do not feel well while being given MEDITAB IRINOTECAN.

While being treated with MEDITAB IRINOTECAN

Things you must do

Keep all appointments with your doctor and always discuss with your doctor any problems during or after treatment with MEDITAB IRINOTECAN.

Tell your doctor as soon as possible if diarrhoea occurs. Diarrhoea is a common side effect of MEDITAB IRINOTECAN. If untreated, severe diarrhoea can be life-threatening.

Your doctor will prescribe loperamide (medicine 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 have more frequent bowel movements than you would normally expect. You must tell your doctor if you cannot get diarrhoea under control within 24 hours after taking loperamide.

You should not take loperamide for more than 48 hours.

Also tell your doctor if you develop a fever in addition to the diarrhoea. In these cases, your doctor may give you antibiotics. If the diarrhoea or fever persists you may become dehydrated and need to go to Accident and Emergency at your nearest hospital for treatment.

You may need to take antibiotics if there are changes in your blood tests indicating a lack of white blood cells. Symptoms of this may include frequent infections such as fever, severe chills, sore throat or mouth ulcers. If this persists, you may need to go to Accident and Emergency at your nearest hospital for treatment.

If you have severe stomach cramps you may need to be treated with antibiotics.

You must use a reliable method of contraception (birth control) while being treated with MEDITAB IRINOTECAN. If pregnancy occurs, consult your doctor.

Things you must not do

Because of the risk of diarrhoea, do not take laxatives during treatment courses with MEDITAB IRINOTECAN. Talk to your doctor if you need more information about this.

Do not start taking any other medicines, prescription or not, without first telling your doctor or pharmacist.
