What AZAPIN is used for
AZAPIN tablets contain azathioprine. This belongs to a group of medicines called immunosuppressants which work by reducing the body’s own natural immunity.
AZAPIN tablets are 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).
AZAPIN tablets are also used to suppress the body’s immunity to treat “autoimmune” conditions like rheumatoid arthritis, and SLE (systemic lupus erythematosus).
AZAPIN tablets may also be used to treat other conditions as determined by your doctor.
AZAPIN 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.

How to take AZAPIN
How much to take
Use AZAPIN tablets only as directed by your doctor. Your doctor has carefully determined your dose of AZAPIN. Your dose of AZAPIN 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 AZAPIN
AZAPIN tablets should only be taken orally. Swallow AZAPIN tablets with a glass of water. Do not crush or chew the tablets
When to take AZAPIN
AZAPIN tablets may sometimes cause mild nausea and vomiting. Take your medicine after food or at bedtime to minimise stomach upset.
How long to take AZAPIN
Do not stop taking AZAPIN tablets without first checking with your doctor. Your doctor will discuss with you how long you need to take AZAPIN tablets. You could have to take AZAPIN for some weeks or months before you will be able to receive the full effects.
Patients that are taking AZAPIN tablets because they have had an organ transplant will need to take AZAPIN 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 AZAPIN as you would normally.
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 AZAPIN tablets 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 (13 11 26) if you think that you or anyone else may have taken too many AZAPIN tablets. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical treatment.
While you are using AZAPIN
Things you must do
You should always tell your doctor about any other medicines that you take , even if you have bought the medicines, vitamins or herbal products without a doctor’s prescription. Some medicines can affect the way AZAPIN works. It is especially important that you tell your doctor if you are taking any of the following:
- Allopurinol (eg. ZYLOPRIM™) – may reduce the removal of azathioprine from your body
- Corticosteroids (cortisone like medicines) these may be prescribed by your doctor to increase the effects of AZAPIN.
- Cytotoxic medicines (eg. mercaptopurine, chlorambucil, cyclosporine, cyclophosamide).
- Warfarin (eg. Coumadin and Marevan). Azathioprine inhibits the anticoagulant effect of warfarin.
Make regular visits to your doctor, so that the doctor will be able to ensure that AZAPIN tablets are working properly for you and that you are not suffering any unwanted side effects. Your doctor may take regular blood tests to check how you are reacting to AZAPIN tablets.
If you have to have or are planning to have an operation, tell your surgeon and anaesthetist that you are taking AZAPIN tablets
