What IMURAN Injection is used for

IMURAN Injection contains azathioprine as the active ingredient. Azathioprine belongs to a group of medicines called immunosuppressants.
IMURAN Injection is used to help prevent the rejection of a transplanted organ such as a kidney, liver or heart. It works by suppressing the body's immune defence system.
IMURAN Injection can also be used to treat other diseases called autoimmune diseases where your immune system is reacting against your own body. These may include:
severe rheumatoid arthritis
systemic lupus erythematosus
chronic active hepatitis
certain skin, muscle, and blood diseases.
IMURAN Injection is usually given in combination with other medicines such as corticosteroids or other immunosuppressive drugs.
Ask your doctor if you have any questions about why IMURAN Injection has been prescribed for you.
Your doctor may have prescribed it for another purpose.
This medicine is only available with a doctor's prescription.
There is no evidence that it is addictive.

How it is given

How much is given

Your doctor will decide what dose you will receive. The dose will depend on the condition being treated, your bodyweight and how you respond to the treatment.
From time to time, while you are being given IMURAN Injection, your doctor will want you to have a blood test. This is to check your blood cell count and to change your dose if necessary.

How it is given

IMURAN Injection will be given to you under the supervision of a doctor.
It is a sterile powder which is dissolved and then diluted with suitable fluids before intravenous injection or infusion into a vein.

How long to have it for

Patients with a transplant will need to be given IMURAN continuously to reduce the risk of organ rejection.
For other conditions, your doctor will discuss with you how long you need to be given this medicine. It could take some weeks or months for it to take full effect.

If you are given too much (overdose)

As this medicine is given to you under the supervision of your doctor, it is extremely unlikely that you will be given too much.

You may need urgent medical attention.
