Short description of Imuran (azathioprine)

Imuran, also known by its generic name azathioprine, is a medication that belongs to a class of drugs known as immunosuppressants. It is commonly used to prevent the rejection of organ transplants, particularly kidney transplants. Imuran works by decreasing the activity of the body’s immune system, thus reducing the risk of the body attacking and rejecting a transplanted organ.

Imuran is also used in the treatment of certain autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease. It helps to reduce inflammation and suppress the overactive immune response seen in these conditions.

How Imuran Works

Imuran works by inhibiting the synthesis of DNA in rapidly dividing cells, which includes immune cells. This action helps to decrease the proliferation of these cells and ultimately reduces the body’s immune response. By suppressing the immune system, Imuran can prevent rejection of transplanted organs and control the inflammation associated with autoimmune diseases.

Side Effects of Imuran

Like any medication, Imuran can cause side effects. Some common side effects of Imuran include nausea, vomiting, diarrhea, and lowered white blood cell count. In some cases, Imuran can also increase the risk of infection and certain types of cancer.

It is important to discuss potential side effects with your healthcare provider before starting Imuran and report any unusual symptoms promptly.

Monitoring While on Imuran

Patients taking Imuran require regular monitoring of their blood cell counts and liver function tests to ensure the medication is not causing any adverse effects. Your healthcare provider will schedule these tests at regular intervals to assess your response to treatment and adjust the dose if necessary.
