What is in this leaflet
This leaflet answers some of the common questions about IMAZAN. It does not contain all the available
information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking IMAZAN against
the benefits the medicine is expected to have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
What IMAZAN is used for
IMAZAN contains azathioprine. This belongs to a group of medicines called immune suppressants which
work by reducing the body’s own natural immunity.
IMAZAN is used to treat patients who have received an organ transplant to help prevent their body from
rejecting the transplanted organs (e.g. a heart or kidney).
IMAZAN is also used to suppress the body’s immunity to treat “autoimmune” conditions like rheumatoid
arthritis, systemic lupus erythematosus or chronic active hepatitis..
IMAZAN may also be used to treat other conditions as determined by your doctor.
IMAZAN is a very powerful medicine. Never let anyone else take your medicine even if his or her
condition seems similar to yours.
Have regular check ups with your doctor.
IMAZAN tablets are not addictive.
Before you take IMAZAN
When you must not take it:
If you are female and you are pregnant or there is a chance that you may become pregnant; or if
you are male and there is a chance that you may father a child.
IMAZAN is not recommended during pregnancy. It may cause birth defects if either the male or
female are using it at the time of conception.
Your partner should take adequate contraceptive precautions while you are taking IMAZAN.
If you are breastfeeding or are planning to breastfeed.
IMAZAN passes into breast milk and may cause serious side effects to your baby.
If you are taking any other medicines or drugs.
If you have ever had an allergy to azathioprine, the active in IMAZAN, any of its ingredients (listed
at the end of this leaflet), or to another immune suppressant medicine (eg. 6-mercaptopurine).
Symptoms of an allergic reaction may be mild or severe. Signs if you are suffering an allergic reaction
usually include some of the following: wheezing, swelling of the lips / mouth, difficulty in breathing,
hayfever, lumpy rash (hives) or fainting.
If you have rheumatoid arthritis which has previously been treated with an alkylating agent (eg.
chlorambucil, melphalan or cyclophosphamide).
If you take IMAZAN after the expiry date (EXP.) printed on the pack. If you take IMAZAN after the
expiry date has passed, it may not work as well.
Do not take IMAZAN if the packaging is torn or shows signs of tampering.
If you're not sure whether you should be taking IMAZAN, talk to your doctor.
All of these factors need to be taken into consideration by your doctor when he/she considers the most
appropriate dose for you.
Before you start to take it:
Tell your doctor if you:
Are allergic to foods, dyes, preservatives or any other medicines;
Have any other medical conditions;
Have liver or kidney disease;
Have been or are considering being vaccinated;
Have been exposed to chickenpox or herpes zoster or have never had chickenpox or herpes

Taking other medicines:

without a prescription from a pharmacy, supermarket or a health food shop.
Some medicines are affected by others. Your doctor or pharmacist will be able to tell you what you should
do when you have to take other medicines while you are on IMAZAN.
Use in children:
IMAZAN may be used in children. Your doctor will advise the dose to use for children.
How to take IMAZAN
How much to take:
Use IMAZAN only as directed by your doctor. Your doctor has carefully determined your dose of
IMAZAN. Your dose of IMAZAN is determined by the condition being treated, your body weight and any
other medical conditions that you may have. Do not alter the amount you are taking or change your
treatment regime unless directed to do so by your doctor.
How to take it:
IMAZAN should only be taken orally.
Swallow IMAZAN with a glass of water. Do not crush or chew the tablets.
When to take it:
Take IMAZAN at the same time every day. Keeping a regular time for taking IMAZAN will help to remind
you to take them.
IMAZAN may sometimes cause mild nausea and vomiting.
Take your medicine after food or at bedtime to minimise stomach upset.
How long to take it:
Do not stop taking IMAZAN without first checking with your doctor. Your doctor will discuss with you
how long you need to take IMAZAN. You could have to take IMAZAN for some weeks or months before you
will be able to receive the full effects.
Patients that are taking IMAZAN because they have had an organ transplant will need to take IMAZAN
continuously to reduce the risk of the body rejecting the transplanted organ.
If you forget to take it:
If it is almost time for your next dose, skip the dose you missed and take your next dose when you
are meant to.
Otherwise, take it as soon as you remember, and then go back to taking IMAZAN as you would
Never take a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist.
Do not use IMAZAN if the blister foil is broken or shows signs of tampering.
If you take too much (overdose):
Immediately telephone your doctor or Poisons Information Centre (Australia: 13 11 26) if you think
that you or anyone else may have taken too many IMAZAN. Do this even if there are no signs of
discomfort or poisoning. You may need urgent medical treatment.
