Consumer Medicine Information
What is in this leaflet
This leaflet answers some of the common questions about AZAPIN. 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 AZAPIN 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 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).
This medicine is 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.
