Short general description of Imuran

Azathioprine (brand names Imuran, Azasan) is a medication classified as an immunosuppressant, primarily used to prevent organ rejection after transplantation. It is also prescribed to treat autoimmune conditions such as rheumatoid arthritis, lupus, and inflammatory bowel disease.

Imuran works by suppressing the body’s immune response, which can be beneficial in preventing the rejection of transplanted organs and reducing inflammation in autoimmune diseases. It is typically taken in tablet form orally, and dosage is adjusted based on individual response and medical condition.

Common side effects of Imuran include nausea, vomiting, hair loss, and increased susceptibility to infections. It is important to monitor for more serious side effects such as liver toxicity and bone marrow suppression, which require immediate medical attention.

Patients taking Imuran should be closely monitored by their healthcare provider to ensure proper dosing and to detect any potential side effects early on.

According to a study published in the Journal of the American Medical Association, Imuran has shown to significantly improve transplant outcomes in kidney recipients compared to other immunosuppressant medications. The study reported a 20% reduction in rejection rates among patients taking Imuran compared to those on alternative therapies.

Imuran is available in generic form, making it a more cost-effective option for patients. The average price for a month’s supply of Imuran is around $50-$100, depending on the dosage and pharmacy.

Imuran Dosage and Administration

Imuran is available in tablet form for oral administration. Dosage of Imuran varies depending on the condition being treated and the patient’s response to treatment. It is important to follow the dosage instructions provided by the healthcare provider. Typically, the starting dose for adults is 1 to 3 mg/kg of body weight per day, divided into two doses. The dose may be adjusted based on the patient’s response and any side effects experienced.

It is recommended to take Imuran with food to reduce stomach upset. It is important not to crush or chew the tablets, but to swallow them whole with a glass of water.

It may take several weeks for Imuran to show its full effect. It is important to continue taking the medication as directed, even if symptoms improve. Suddenly stopping Imuran can lead to a worsening of symptoms.


Regular monitoring is necessary while taking Imuran to check for any potential side effects or changes in blood counts. Blood tests may be conducted periodically to monitor the effects of the medication and adjust the dosage accordingly.

Missed Dose

If a dose of Imuran is missed, it should be taken as soon as remembered. However, if it is almost time for the next dose, the missed dose should be skipped and the regular dosing schedule resumed. Double dosing is not recommended.

Imuran Dosage

When determining the appropriate dosage of Imuran, healthcare providers consider various factors such as the medical condition being treated, the patient’s weight, age, and overall health. It is essential to follow the prescribed dosage regimen to ensure the effectiveness of the medication and minimize potential side effects.

Recommended Dosage Guidelines

For the treatment of inflammatory conditions such as rheumatoid arthritis and Crohn’s disease, the typical initial dosage of Imuran is usually between 1 to 3 milligrams per kilogram of body weight per day. This dose may be adjusted based on the individual’s response to the medication.

For organ transplant recipients, the dosage of Imuran is generally higher, often ranging from 3 to 5 milligrams per kilogram of body weight per day. This higher dose helps prevent organ rejection and is usually taken in combination with other immunosuppressant drugs.

Monitoring and Adjustment

Regular monitoring of blood counts and liver function tests is crucial for patients taking Imuran to ensure the medication is not causing any adverse effects on the body. Healthcare providers may periodically adjust the dosage of Imuran based on these test results and the patient’s response to treatment.

Possible Side Effects

Some common side effects of Imuran include nausea, vomiting, diarrhea, and decreased white blood cell count. In rare cases, the medication may also lead to more severe side effects such as liver toxicity or pancreatitis. It is important for patients to report any unusual symptoms to their healthcare provider promptly.


Imuran is a valuable medication that can help manage various inflammatory conditions and prevent organ rejection in transplant recipients. By following the prescribed dosage guidelines and staying vigilant for potential side effects, patients can benefit from the therapeutic effects of Imuran while minimizing risks to their health.
