Pregnancy

• It is not recommended that you become pregnant during treatment with oxaliplatin and must use an effective method of contraception. Female patients should take appropriate contraceptive measures during and after cessation of therapy continuing for 4 months.

Ask your doctor or pharmacist for advice before taking any medicine.

Oxaliplatin treatment may result in an increased risk of dizziness, nausea and vomiting, and other neurological symptoms that affect walking and balance. If this happens you should not drive or operate machinery. If you have vision problems while taking Oxaliplatin, do not drive, operate heavy machines or engage in dangerous activities.

The dose of Oxaliplatin is based on your body surface area. This is calculated from your height and weight.

The usual dose for adults including the elderly is 85mg/m² of body surface area.

The dose you receive will also depend on results of blood tests and whether you have previously experienced side effects with Oxaliplatin.

• Oxaliplatin will be prescribed for you by a specialist in cancer treatment.
• You will be treated by a healthcare professional, who will have made up the required dose of Oxaliplatin.
• Oxaliplatin is given by slow injection into one of your veins (an intravenous infusion) over a 2 to 6 hour period.
• Oxaliplatin will be given to you at the same time as folinic acid and before the infusion of 5-fluorouracil.

You should usually receive your infusion once every 2 weeks.

The duration of the treatment will be determined by your doctor.

Your treatment will last a maximum of 6 months when used after complete resection of your tumour.

As this medicine is administered by a healthcare professional it is highly unlikely that you will be given too much or too little.

In case of overdose, you may experience increased side effects. Your doctor may give you appropriate treatment for these side effects.

Very common (may affect more than 1 in 10 people)

• Oxaliplatin can affect the nerves (peripheral neuropathy). You may feel a tingling and/or numbness in the fingers, toes, around the mouth or in the throat, which may sometimes occur in association with cramps.
  These effects are often triggered by exposure to cold e.g. opening a refrigerator or holding a cold drink. You may also have difficulty in performing delicate tasks, such as buttoning clothes. Although in the majority of cases these symptoms resolve themselves completely there is a possibility of persistent symptoms of peripheral sensory neuropathy after the end of the treatment. Some people have experienced a tingling, shock-like sensation passing down the arms or trunk when the neck is flexed.
• Oxaliplatin can sometimes cause an unpleasant sensation in the throat, in particular when swallowing, and give the sensation of shortness of breath. This sensation, if it happens, usually occurs during or within hours of the infusion and may be triggered by exposure to the cold. Although unpleasant, it will not last long and goes away without the need for any treatment. Your doctor may decide to alter your treatment as a result.
• Oxaliplatin may cause diarrhoea, mild nausea (feeling sick) and vomiting (being sick); however medication to prevent the sickness is usually given to you by your doctor before treatment and may be continued after treatment.
• Oxaliplatin causes temporary reduction in the number of blood cells. The reduction of red cells may cause anaemia (a reduction of red cells), abnormal bleeding or bruising (due to a reduction in platelets). The reduction in white blood cells may make you prone to infections.
  Your doctor will take blood to check that you have sufficient blood cells before you start treatment and before each subsequent course.

• Fever, rigors (tremors), mild or severe tiredness, body pain, Weight changes, loss or lack of appetite, taste disorders, constipation,
