Patient information leaflet

What is it and what is it used for?

An antibody is a natural substance made by the body which binds to foreign substances to help remove them from your body. You produce many different kinds of antibodies.

LeukoScan (sulesomab) is a special kind of antibody which binds to the surface of certain kinds of blood cells called leukocytes. It is produced in mice and purified so that it can be used in humans. When it is combined to the radioactive technetium isotope and injected into your vein, it finds an abnormal accumulation of white blood cells and attaches to them. One to eight hours later after the injection you will be placed on a special table and pictures will be taken with standard nuclear cameras. This helps your doctor make a diagnosis and evaluate the extent of your illness. The doctor does this by using a special imaging camera that reveals areas of radioactivity to see where the infections are located. This medicine is for diagnostic use only.

LeukoScan is used to determine the presence of infections in long bones. Shortly after mixing the LeukoScan with the radioactive technetium isotope, the doctor will inject it into your vein. One to eight hours later you will be placed on a special table and pictures will be taken with standard nuclear cameras to see where the infections are located.

LeukoScan is an antibody fragment which is linked to a radioactive substance called technetium. LeukoScan is used in patients with suspected infection of the bone called osteomyelitis. The antibody is able to bind to the surface of white blood cells which infiltrate the area of infection. When the radioactive antibody binds to the white blood cells, your doctor can determine where the infection is located by using a special imaging camera that reveals areas of radioactivity. The doctor can also determine how much disease there is. This will help the doctor determine whether there is infection in the bone and what kind of treatment to use.

What should you consider before use?

Important information about some ingredients of LeukoScan

If you have been told that you have an intolerance to some sugars, inform your doctor before you are given this medicine.

How is it used?

Dosage

You will receive a single dose of 0.25 mg of LeukoScan. It will contain the radioactive technetium isotope in an amount called 740-1110 MBq.

Method and/or route(s) of administration

Your doctor will prepare the LeukoScan and the radioactive isotope technetium in a volume of 1.5 ml. 0.25 mg of LeukoScan will be labelled with 740-1110 MBq of technetium. This material will then be injected into your vein. This dose of radioactivity is safe and will be gone from the body in about 24 hours.

Frequency of administration

LeukoScan is prepared for a single injection. If your doctor decides to give it to you again after several weeks or several months, your blood should be tested first to see if you have developed an allergy to LeukoScan.

If you take more LeukoScan than you should

The maximum amount of LeukoScan that can be administered has not been determined. Patients have been given four times the amount you will receive with no adverse reactions.
In the unlikely event of the administration of a radiation overdose with LeukoScan, the absorbed dose to the patient may be reduced by increased oral or intravenous intake of fluids to promote excretion of the radiolabel.

If you stop using LeukoScan

LeukoScan is prepared for a single injection.

If you have any further questions on the use of this product, ask your doctor.
