The organ transplant is basically a surgical operation through which a failing or damaged organ in the human body can be removed and replaced with the functioning one. The donated organ can be from a deceased Or living donor. In a few cases an artificial organ can be used.

Azathioprine is recommended in order to prevent the rejections of liver Or kidney allografts, basically in conjunction with the other therapies including the corticosteroids, immunosuppressants, and local radiation therapy. The administration protocol initiated either at about the time of the transplantation or within the following a couple of days.
Note: A few other indications of azathioprine are: Rheumatoid Arthritis & Inflammatory Bowel Disease.
Dose: The dose of Azathioprine is needed in order to prevent as well as resist the rejection and to reduce/minimize the toxicity would vary with the individual patients; this required careful management. The starting dose is 3 to 5 mg/kg per day, beginning at about the time of the transplant. This drug should be given as a single daily dose on the day of, and in less cases 1-3 days prior to transplantation. Azathioprine dose must not be boosted to toxic levels just because of the threatened rejection.
When to Take: Taking the medication twice daily instead of all at once, or taking it after eating, may help avoid these problems.
Missed Dose: If you forgot to consume a dose, catch it immediately if you remember. But, don’t take a couple of doses at one time without informing a transplant office.
Precautions: Patients who are on azathioprine 50 mg tablet should have complete blood counts, including counts of platelet, weekly during initial month, two times in a month for the 2'nd and 3'rd months of the treatment.
