Medically reviewed.

Imuran (azathioprine) is an immunosuppressive medication used to prevent organ rejection following liver transplantation. Although it is used less often than newer agents, it remains an option in selected transplant recipients. It lowers the activity of immune cells that could attack the transplanted liver, which helps prevent rejection and supports long-term graft survival. Treatment decisions should always be individualized and guided by your transplant team.

This page covers Imuran's role after liver transplant — how it works, who may be prescribed it, how it is used, benefits, side effects, and monitoring. You can also connect with a liver specialist near you for personalized guidance on whether Imuran fits your care plan.

ABOUT IMURAN TREATMENT

What is Imuran (Azathioprine)?

Imuran is a prescription medicine that contains azathioprine. It is an immunosuppressant, a medicine that lowers the activity of the immune system. Imuran is used to prevent organ rejection following liver transplantation.

Although Imuran is used less often than newer agents, it remains an option in selected transplant recipients. It reduces the immune attack against the transplanted liver and supports long-term graft survival. The graft is the transplanted liver.

Imuran can be used with other core immunosuppressants. It is part of long-term care after transplant, which includes follow-up visits and regular laboratory testing.

WHO IMURAN MAY BE SUITABLE FOR

Who May Be Prescribed Imuran?

Imuran is used in people who have received a liver transplant. Your healthcare provider may prescribe it if you need long-term immunosuppressive therapy, if other medications are not suitable for you, or if you need additional immunosuppressive support.

Because every patient's health profile is different, there is no one-size-fits-all answer to who should take Imuran. Treatment decisions are individualized and should be made by your transplant team after a full assessment of your health and treatment needs.

ELIGIBILITY OVERVIEW

Who Imuran May Be Right For

Imuran May Be Considered For People Who

Your healthcare provider may prescribe Imuran if:

  • You have received a liver transplant
  • You require long-term immunosuppressive therapy
  • Alternative medications are not suitable
  • Additional immunosuppressive support is needed

Ongoing Review During Treatment

Imuran treatment is reviewed over time. Your care team uses the following to guide your dose and care:

  • Your body weight
  • Your blood counts
  • Your response to treatment
  • Regular laboratory monitoring and signs of infection

HOW IMURAN CAN HELP PROTECT YOUR TRANSPLANT

How Does Imuran Work?

Imuran blocks DNA synthesis in rapidly dividing immune cells. It also suppresses the activity of T- and B-lymphocytes, which are white blood cells of the immune system.

By calming these cells, Imuran reduces the immune attack against the transplanted liver. This helps prevent rejection episodes and supports long-term graft survival.

Imuran can be used with other immunosuppressants. Regular monitoring helps your care team keep treatment safe.

TRANSPLANT BENEFITS

How Imuran May Support Your Transplant

Targeting Fast-Dividing Immune Cells

Imuran blocks DNA synthesis in immune cells that divide quickly. It also suppresses T- and B-lymphocytes, which are white blood cells. Together, these actions reduce the immune attack against your transplanted liver.

Lowering the Chance of Rejection Episodes

A rejection episode happens when the immune system attacks the transplanted organ. Imuran reduces that attack. This helps prevent rejection episodes and supports long-term graft survival, which means the new liver keeps working.

Long-Term Maintenance Therapy

Most people take Imuran as maintenance therapy for many years, and many need it for life. Your transplant team may change the dose as lab results, transplant stability, and your overall needs change. Do not stop or change it on your own.

A Role Within a Combination of Medicines

Newer agents are used more often, but Imuran remains an option for selected transplant recipients. Your team may choose it when other medicines are not suitable or when you need added immunosuppressive support. It can be used with other immunosuppressants.

Key Takeaway:

Imuran lowers the immune activity that can lead to rejection and supports long-term graft survival. It should only be started and monitored under the guidance of your transplant team.

TREATMENT PROCESS

How is Imuran Used?

Preparation

Imuran is available as oral tablets and as an intravenous formulation. Ask your transplant team or pharmacist which form you have been prescribed.

Dosage

Typical maintenance doses range from 50-150 mg once daily (approximately 1-3 mg/kg/day). Your care team individualizes the dose according to your body weight, blood counts, and treatment response.

Administration

Take Imuran exactly as prescribed by your healthcare provider, and do not miss doses.

Treatment Duration

Imuran is generally used as long-term maintenance immunosuppressive therapy after liver transplantation. Treatment often continues for many years, and in many patients lifelong therapy is required unless the transplant team decides that medication changes are appropriate. The dose may be adjusted over time based on laboratory monitoring and overall immunosuppressive needs.

Storage

Store Imuran at room temperature, away from moisture and heat.

Monitoring

Regular monitoring of complete blood counts, liver function, and signs of infection is required. Attend all scheduled follow-up appointments and laboratory testing, and report side effects or unusual symptoms to your healthcare provider.

BENEFITS AND SAFETY

Benefits and Common Side Effects

Imuran (azathioprine) helps protect a transplanted liver by lowering the immune activity that leads to rejection. It supports long-term graft survival, has a long history of use in transplant care, and can be used with other immunosuppressants.

As with any medication, Imuran may cause side effects. Because it lowers immune activity, your healthcare provider will monitor your blood counts, liver function, and signs of infection throughout treatment, and will assess whether Imuran remains a suitable option for you.

BENEFITS

Key Benefits of Imuran

Benefits of Imuran

Protection of the Transplanted Liver

Rejection happens when the immune system attacks a transplanted organ. The main benefit of Imuran is that it lowers this attack and helps protect the liver you received, which is why it is part of care after liver transplant.

Graft Survival Over Time

Imuran supports graft survival, meaning your transplanted liver can keep working over time. This benefit comes from steady use as maintenance therapy, often for many years, rather than from a short course of treatment.

Track Record in Transplant Care

Imuran has a long history of use in transplant care. Newer agents are used more often, but your transplant team can still draw on this experience when it weighs options for selected transplant recipients.

Flexibility in Treatment Planning

Imuran can be taken together with other immunosuppressants. It also remains an option when other medications are not suitable or when additional immunosuppressive support is needed, which gives your team more flexibility in planning your care.

Common Side Effects of Imuran

  • Nausea
  • Low white blood cell count
  • Increased infection risk
  • Fatigue
  • Liver enzyme abnormalities

Your healthcare provider will discuss the potential benefits and risks before treatment and provide ongoing support, including regular blood and liver testing, to ensure safe use.

SUPPORTING YOUR RESULTS

Lifestyle Changes That Support Imuran Treatment

Daily habits play an important role alongside Imuran. Because the medicine lowers immune activity, infection prevention and sun protection matter.

Regular follow-up appointments and laboratory testing help monitor medication safety and transplant function.

Areas that may support treatment:

  • Alcohol — avoiding alcohol unless your transplant team approves it
  • Infection prevention — practicing good hand hygiene and other infection prevention measures
  • Sun protection — using sunscreen and protective clothing to reduce skin cancer risk
  • Vaccines — avoiding live vaccines unless your healthcare provider approves them
  • Follow-up care — attending all follow-up appointments and laboratory testing
