How RIBOMUSTIN is given?

Your treatment with RIBOMUSTIN will take place in a specialised medical unit, under the supervision of a doctor experienced in the use of medicines that treat cancer.
Treatment should not be started if your white blood cells (leukocytes) have fallen to counts below 3,000 cells/µL and/or your blood platelets have fallen to counts below 75,000 cells/µL. Your doctor will determine these values at regular intervals.

How much is given

Your doctor will decide what dose you will receive. The dose will be calculated from your height and weight. It will also depend on factors such as kidney function, liver function and other medicines you are being given.
Dose for Chronic Lymphocytic Leukaemia:
100mg per square metre of your body surface area
Cycle should be repeated after 4 weeks up to 6 times.
Dose for progressing Non-Hodgkin's Lymphoma:
120mg per square metre of your body surface area on days 1 and 2
Cycle should be repeated after 3 weeks up to 6 times
Dose for previously untreated indolent Non-Hodgkin's Lymphoma and Mantle Cell Lymphoma:
90mg per square metre on days 1 and 2

Your doctor may change the dose during treatment depending on your response.

RIBOMUSTIN is administered into a vein over 30-60 minutes in various dosages, either alone (monotherapy) or in combination with other medicines.
Unintentional injection into the tissue outside blood vessels (extravasal injection) should be stopped immediately. The needle should be removed after a short aspiration. Thereafter, the affected area of tissue should be cooled. The arm should be elevated. Additional treatments like the use of corticosteroids are not of clear benefit.

How long is RIBOMUSTIN given

There is no time limit laid down as a general rule for treatment with RIBOMUSTIN. Duration of treatment depends on disease and response to treatment.

If you are given too much RIBOMUSTIN

As RIBOMUSTIN is given to you under supervision of your doctor, it is very unlikely that you will receive too much.

You should immediately:
phone the Poisons Information Centre
(by calling 13 11 26), or
contact your doctor or nurse, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.

What should I know while using RIBOMUSTIN?

Things you should do

Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some blood, urine or other tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Keep follow-up appointments with your doctor. It is important to have your follow-up doses of RIBOMUSTIN at the appropriate times to get the best effects from your treatment.
Tell any other doctors, dentists and pharmacists who are treating you that you are using RIBOMUSTIN.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.
If you become pregnant or your partner becomes pregnant while being given RIBOMUSTIN, tell your doctor immediately.

Decrease in blood cells

RIBOMUSTIN can lower the number of white blood cells and platelets in your blood. This means that you have an increased chance of getting an infection or bleeding. The following precautions should be taken to reduce your risk of infection or bleeding:
Avoid people who have infections. Check with your doctor immediately if you think you may be getting an infection, or if you get a fever, chills, cough, hoarse throat, lower back or side pain.
Be careful when using a toothbrush, toothpick or dental floss. Your doctor, dentist, nurse or pharmacist may recommend other ways to clean your teeth and gums. Check with your doctor before having any dental work.
Be careful not to cut yourself when you are using sharp objects such as a razor or nail cutter.

Driving or using machines

Do not drive or use any machines or tools until you know how RIBOMUSTIN affects you.
This medicine may cause sleepiness, dizziness, lack of coordination or fatigue in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.

Looking after your medicine

Follow the instructions in the carton on how to take care of your medicine properly.
RIBOMUSTIN should be kept below 25°C, protected from light.
Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:
in the bathroom or near a sink, or
in the car or on window sills.
Keep it where young children cannot reach it.

Getting rid of any unwanted medicine

RIBOMUSTIN will be disposed of appropriately by the healthcare professionals.
