What CAMPTOSAR is used for
CAMPTOSAR 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.
CAMPTOSAR may be used once spread of cancer beyond the bowel is first diagnosed. At this time CAMPTOSAR will be given in combination with other anticancer medicines. Alternatively, CAMPTOSAR 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 CAMPTOSAR has been prescribed for you.
Your doctor may have prescribed it for another purpose.
Use in children
It is not known if CAMPTOSAR is safe and effective in the treatment of children.
Before being treated with CAMPTOSAR
When CAMPTOSAR must not be given
CAMPTOSAR must not be given if you:
- are allergic to irinotecan hydrochloride or any of the ingredients listed at the end of this leaflet
- are or may become pregnant
- are breastfeeding or intend to breastfeed.
Before treatment with CAMPTOSAR
You should be treated with CAMPTOSAR 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 CAMPTOSAR, to help stop you vomiting or feeling sick after the treatment. You will probably also have a blood test before each treatment.
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 Crigler-Najjar 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 CAMPTOSAR.
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 you buy without a prescription from a pharmacy, supermarket, naturopath or health food shop.
Some medicines and CAMPTOSAR 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 CAMPTOSAR is given
CAMPTOSAR 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 CAMPTOSAR be given in different treatment courses depending on whether CAMPTOSAR is given alone or in combination with other anticancer medicines.
Combination Treatment Courses
When CAMPTOSAR 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
CAMPTOSAR 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 CAMPTOSAR should be interrupted if you get severe diarrhoea or other intolerable side effects.
Your doctor will decide the most appropriate dose of CAMPTOSAR to be given.
Ask your doctor if you want more information about the dose of CAMPTOSAR and the other medicines you will be receiving and how they are given while you are being treated with CAMPTOSAR.
After your first treatment course, the dose of CAMPTOSAR 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 CAMPTOSAR.
While being treated with CAMPTOSAR
Things you must do
Keep all appointments with your doctor and always discuss with your doctor any problems during or after treatment with CAMPTOSAR.
Tell your doctor as soon as possible if diarrhoea occurs.
Diarrhoea is a common side effect of CAMPTOSAR. If untreated, severe diarrhoea can be life-threatening.
Your doctor will prescribe loperamide (a 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 CAMPTOSAR. 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 CAMPTOSAR.
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.
