Active ingredient(s): imatinib mesilate

Consumer Medicine Information (CMI)

This leaflet provides important information about using IMANIB. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using IMANIB.

Where to find information in this leaflet:

1. Why am I using IMANIB?

IMANIB contains the active ingredient imatinib. IMANIB belongs to a group of anti-cancer medicines known as tyrosine kinase inhibitors.

IMANIB is used to treat children and adults who have certain types of cancer and leukemia, including chronic myeloid leukaemia (CML) and acute lymphoblastic leukaemia with Philadelphia chromosome positive (Ph- positive ALL).

IMANIB 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.

Gastro-intestinal stromal tumours (GIST).

This is a type of cancer of the stomach and bowels. This cancer affects the tissue that surrounds the stomach and bowels and the cells grow uncontrollably.

Dermatofibrosarcoma protuberans (DFSP).

DFSP is a cancer of the tissue beneath the skin in which some cells start growing out of control.

IMANIB works by slowing the growth of and killing cancer cells while leaving normal cells alone.

2. What should I know before I use IMANIB?

  • you are allergic to imatinib, or any of the 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

4. How do I use IMANIB?

How much to take

  • Your doctor will tell you exactly how many tablets of IMANIB to take
  • Do not exceed the recommended dose prescribed by your doctor
  • Follow the instructions provided and use IMANIB until your doctor tells you to stop
  • Your doctor may direct you to take a higher or lower dose or stop treatment depending on how your body responds to IMANIB.
  • IMANIB 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

When to take IMANIB

  • Take IMANIB every day; at the same time, with water and food for as long as your doctor recommends

How to take IMANIB

  • Take IMANIB with a large glass of water and food. This will help avoid stomach irritation
  • If you are unable to swallow the tablets:
  • Put the required tablets in a glass of water or apple juice (approximately 50 mL for a 100 mg tablet or 200 mL for a 400 mg tablet)
  • Stir with a spoon to completely dissolve the tablets
  • Drink immediately

If you forget to use IMANIB

IMANIB should be taken regularly at the same time each day. If you miss your dose at the usual time, take the missed dose as soon as you remember, then continue with your normal schedule.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

If you take too much IMANIB

If you think that you have used too much IMANIB, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using IMANIB?

Things you should do

Make sure you follow your doctor's instructions carefully and keep all appointments.

You will need regular check-ups to make sure the treatment is working. Regular blood tests, weight checks and urine tests can also find side effects before they become serious.

Use a method of contraception to prevent pregnancy during treatment and for 15 days after ending treatment.

Some children taking IMANIB may have slower than normal growth. Growth will be monitored at regular visits by your doctor.

Call your doctor straight away if you

  • Become pregnant or think you might be pregnant
  • Think you might be having an allergic reaction to IMANIB treatment

Remind any doctor, dentist or pharmacist you visit that you are using IMANIB.

Things you should not do
