Your doctor may use a combination of Campto with 5-fluorouracil/folinic acid (5FU/FA) and bevacizumab to treat your cancer of the colon and rectum.

Your doctor may use a combination of Campto with capecitabine with or without bevacizumab to treat your cancer of the colon and rectum.

Your doctor may use a combination of Campto with cetuximab to treat cancer of the large intestine (KRAS wild-type) that is of a certain type known to display cell markers referred to as epidermal growth factor receptors (EGFR) which are blocked by the monoclonal antibody.

If you need any further information on your condition, please ask your doctor.

As with all anti-cancer medicines the use of Campto is associated with a number of side-effects which may be serious. These side-effects require special management to minimise the risk of complications. You will be treated by a specialist team experienced in using these kinds of treatments and managing their side-effects, which are usually temporary. However, it is essential that you read the section “Does Campto have any side-effects?” and follow the instructions carefully if you get any of the symptoms described.

Can you drive or operate machinery?

Campto may make you feel dizzy or cause visual disturbances. If this happens to you do not drive or operate machinery.

How will you be given Campto?

Campto will be given as an infusion into your veins over a period of 30 to 90 minutes. The amount of Campto you are given will depend on your age, size and general medical condition. It will also depend on any other treatment you may have received for your cancer. Your doctor will calculate your body surface area in square metres (m2).

  • If you have previously been treated with 5-fluorouracil you will normally be treated with Campto alone starting with a dose of 350 mg/m2 every 3 weeks.
  • If you have not had previous chemotherapy you will normally receive 180 mg/m2 Campto every two weeks. This will be followed by folinic acid and 5-fluorouracil.
  • If you receive Campto in combination with cetuximab, Campto must not be administered earlier than 1 hour after the end of the cetuximab infusion. Please follow the advice of your doctor regarding your current treatment.

These dosages may be adjusted by your doctor depending on your condition and any side-effects you may have.

If you have ANY DIARRHOEA it is IMPORTANT that you follow these instructions carefully.

  • if your diarrhoea starts less than 24 hours after the infusion (“early diarrhoea”) you should contact your doctor or nurse immediately and they will give you a suitable treatment.

This “early diarrhoea” may be accompanied by other symptoms such as

  • sweating
  • abdominal cramps
  • watering eyes
  • visual disturbance
  • dizziness
  • low blood pressure
  • feeling unwell
  • excessive mouth watering

Tell your doctor or nurse about all your symptoms.

  • if you have nausea and vomiting as well as diarrhoea
  • if you have any fever as well as the diarrhoea
  • if you still have diarrhoea 48 hours after starting the diarrhoea treatment

Do not take any treatment for diarrhoea other than that given to you by your doctor or nurse and the fluids described above.

Campto (Irinotecan Hydrochloride Trihydrate)Neutropenia

INSTRUCTIONS FOR USE / HANDLING, PREPARATION AND DISPOSAL GUIDE FOR USE WITH CAMPTO CONCENTRATE FOR SOLUTION FOR INFUSION

USE/HANDLING

As with other neoplastic agents, Campto must be prepared and handled with caution. The use of glasses, masks and gloves is required. If Campto solution or infusion solution should come in contact with the skin, wash immediately and thoroughly with soap and water. If Campto solution or infusion solution should come into contact with the mucous membranes, wash immediately with water.

PREPARATION FOR THE INTRAVENOUS SOLUTION

As with any other injectable drugs, the Campto solution must be prepared aseptically.

If any precipitate is observed in the vials or after reconstitution, the product should be discarded according to standard procedures for cytotoxic agents.

Aseptically withdraw the required amount of Campto solution from the vial with a calibrated syringe and inject into a 250 ml infusion bag or bottle containing either 0.9% (w/v) sodium chloride or 5% (w/v) glucose solution. The infusion should then be thoroughly mixed by manual rotation.

It is recommended, that in order to reduce microbiological hazard, the infusion solutions should be prepared immediately prior to use and infusion commenced as soon as practicable after preparation.   If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2 to 8°C, unless reconstitution / dilution (etc) has taken place in controlled and validated aseptic conditions.

Campto infusion should be infused into a peripheral or central vein.

Campto should not be delivered as an intravenous bolus or an intravenous infusion shorter than 30 minutes or longer than 90 minutes.

DISPOSAL

All materials used for dilution and administration should be disposed of according to hospital standard procedures applicable to cytotoxic agents.
