Savene contains the active substance dexrazoxane, which acts as an antidote to anti-cancer medicines called anthracyclines.
Most anti-cancer medicines are administered intravenously (into a vein). Occasionally an accident occurs and the medicine is infused outside the vein and into the surrounding tissue or leaks from the vein into the surrounding tissue. This event is called extravasation. It is a serious complication as it can cause severe tissue damage.
Savene is used to treat anthracyline extravasation in adults. It can reduce the amount of tissue damage caused by anthracycline extravasation.
Talk to your doctor or nurse before using Savene:
Savene should not be administered to children below the age of 18 years.
Tell your doctor or nurse if you are taking, have recently taken, or might take any other medicines.
In particular, tell your doctor or nurse if you are taking or may take any of the following medicines:
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby ask your doctor for advice before taking this medicine.
Savene should not be administered if you are pregnant.
You must not breast-feed while you are treated with Savene.
If you are sexually active, you are advised to use effective birth control to prevent pregnancy during and for six months after treatment, whether you are male or female (see section 2 ‘Do not use Savene’)
There is limited information about the effect of Savene on fertility – if you have a concern about this speak to you doctor.
Dizziness, tiredness and sudden fainting have been reported in a few patients treated with Savene. The treatment is considered to have a limited influence on the ability to drive and use machines.
The Savene solvent contains 98 mg potassium in each 500 ml bottle which may be harmful to people on a low-potassium diet or who have kidney problems. If you are at risk of high potassium levels in your blood, your doctor will monitor this.
Savene solvent also contains 1.61 g sodium (main component of cooking/table salt) in each 500 ml bottle. This is equivalent to 81% of the recommended maximum daily dietary intake of sodium for an adult.
Savene will be given to you under the control of a doctor experienced in the use of anti-cancer treatments.
The dose will depend on your height, weight and kidney function. Your doctor will calculate your body surface area in square meter (m2) to determine the dose you should receive. The recommended adult dose (with normal kidney function) is:
Day 1: 1000 mg/m2
Day 2: 1000 mg/m2
Day 3: 500 mg/m2
Your doctor may reduce your dose if you have kidney problems.
Savene will be given by infusion into one of your veins. The infusion will last 1-2 hours.
You will receive your infusion once daily for 3 consecutive days. The first infusion will be given as soon as possible and within the first six hours after extravasation of an anthracycline medicine. Savene infusion will be given at the same time every day of your treatment.
Savene will not be used again at the time of your next anthracycline cycle, except if extravasation occurs again.
If you receive more Savene than you should, you will be closely monitored with specific attention to your blood cells, potential gastro-intestinal signs, skin reactions and hair loss.
If Savene comes into contact with the skin, the affected area should immediately be rinsed thoroughly with water.
If you have any further questions on the use of this medicine, ask your doctor or nurse.
