What this medicine is used for

The name of your medicine is IMATINIB APOTEX. It contains the active ingredient imatinib mesilate.
Imatinib is used to treat adults and children/adolescents who have chronic myeloid leukaemia (CML) and acute lymphoblastic leukaemia with Philadelphia chromosome positive (Ph-positive ALL).
CML and ALL are types of leukaemia in which an abnormal chromosome produces an enzyme that leads to uncontrolled growth of white blood cells. Imatinib kills the abnormal cells while leaving normal cells alone.
Imatinib is also used to treat adults for:
myelodysplastic / myeloproliferative diseases (MDS/MPD).
These are a group of blood diseases in which some blood cells start growing out of control.
Aggressive systemic mastocytosis (ASM).
It is a cancer in which certain blood cells, called "mast" cells, grow out of control.
Hypereosinophilic syndrome (HES) and or chronic eosinophilic leukaemia (CEL).
These are blood diseases in which some blood cells, named "eosinophils", start growing out of control.
Dermatofibrosarcoma protuberans (DFSP).
DFSP is a cancer of the tissue beneath the skin in which some cells start growing out of control.
Imatinib works by slowing the growth of abnormal cells. Imatinib kills the abnormal cells while leaving normal cells alone.
Ask your doctor if you have any questions about why it has been prescribed for you.
Your doctor, however, may prescribe it for another purpose.
Imatinib is only available with a doctor's prescription. It is not addictive.

Use in children

There is not enough information to recommend the use of imatinib in children under 3 years of age for most uses. For use in CML, there is no experience with the use of imatinib in children below 2 years of age. For acute lymphoblastic leukaemia with Philadelphia chromosome positive (Ph-positive ALL), there is no experience with the use of imatinib in children below 1 year of age.

Before you take this medicine

When you must not take it

Do not take this medicine if you have ever had an allergic reaction to imatinib (the active ingredient) or to any of the other ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
In that case, return the medicine to your pharmacist.

Before you start to take it

Tell your doctor if you are pregnant or intend to become pregnant.
This medicine may be harmful to your unborn baby. If it is necessary for you to take it during pregnancy, your doctor will discuss with you the risks and benefits involved.
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known whether imatinib passes into breast milk. Because this medicine could affect your baby, breastfeeding is not recommended.
Tell your doctor if you have ever had any of the following medical problems or procedures:
kidney or liver problems
problems with your heart
you have had your thyroid gland removed.
Your doctor may want to take special precautions in that case.

Taking other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.
Some medicines and imatinib may interfere with each other. These include many medicines that are eliminated from the body through the liver:
St. John's wort, a herbal medicine found in many products that you can buy without a prescription
paracetamol, a medicine found in many common pain relievers and cold remedies (e.g. Panadol®, Panadeine®, Codral®, Tylenol®) which are known to be associated with liver toxicity.
A patient, who was taking paracetamol regularly for fever, died of acute liver failure. Although the cause is currently unknown, special caution should be exercised when using paracetamol and imatinib.
antibiotic medicines such as rifampicin, ketoconazole, erythromycin, clarithromycin, itraconazole
antiviral medicines used to treat HIV/AIDS
dexamethasone, a steroid medicine
medicines for high cholesterol, such as simvastatin
medicines used to treat epilepsy, such as phenytoin, carbamazepine, phenobarbitone
warfarin, a medicine used to prevent blood clots
some medicines used to treat mental disorders and depression
some medicines used to treat high blood pressure and heart problems
cyclosporin
You may need to take different amounts of these medicines or you may need to take different medicines. Your doctor and pharmacist have more information.
If you have not told your doctor about any of these things, tell him/ her before you start taking this medicine

How much to take

For CML, the usual dose for an adult is 400 to 600 mg each day and the maximum dose is 800 mg each day. The dose depends on what stage of CML you have. For Ph-positive ALL the usual dose is 600 mg each day. For children treated with CML and Ph-positive ALL, the dose depends on the size of the child.
For MDS/MPD, the starting dose is
400 mg.
For ASM and HES/CEL, the usual starting dose is 400 mg. For some patients the starting dose may be 100 mg.
For DFSP, the starting dose is 800 mg per day.
Daily dose of 400 mg should be taken as one capsule of 400 mg once a day.
Daily dose of 600 mg should be taken as either:
six capsules of 100 mg or
one capsule of 400 mg plus two capsules of 100 mg once a day.
Daily dose of 800 mg should be taken as 400 mg twice a day, in the morning and in the evening.
Your doctor may direct you to take a higher or lower dose, depending on your response to imatinib.
Imatinib is usually taken as a single dose each day. However, your doctor may want you to take them in two doses, one in the morning and one in the evening.

How to take it

Take the medicine with a large glass of water and food.
This will help to avoid irritating the lining of your oesophagus (food pipe) and stomach.
Swallow the capsules whole with a large glass of water.
Do not open or crush the capsules unless you have difficulty in swallowing (e.g. in children).
If you are unable to swallow the capsules, you can open them up and pour the powder into a glass of still water or apple juice.
If you are a woman who is pregnant or might get pregnant and are trying to open the capsules, you should handle the contents with caution in order to avoid skin-eye contact or inhalation.
You should wash your hands immediately after opening the capsules.
For the best effect, take the medicine at about the same time each day.
Taking them at the same time each day will help you to remember to take them.

How long to take it

Continue taking this medicine every day for as long as your doctor prescribes.
Your doctor will keep a close check on you to make sure you are still benefiting from treatment.

If you forget to take it

Take the missed dose as soon as you remember, then continue with your normal schedule.
Do not take a double dose to make up for the one that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Keep the telephone numbers for these places handy.
