Imuran Side Effects: An Introduction

As with any medicine, side effects are possible with Imuran^® (azathioprine). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If Imuran side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.

(This article covers many, but not all, of the possible side effects with Imuran. Your healthcare provider can discuss a more complete list of Imuran side effects with you.)

Common Side Effects of Imuran

Imuran has been studied thoroughly in clinical trials, in which the side effects of a group of people taking the drug are documented and compared to another group not taking the medicine. As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.

In these studies, the most common Imuran side effects included:

Leukopenia (low levels of white blood cells called leukocytes) -- in up to 50 percent of people
Infections -- up to 20 percent
Nausea and vomiting -- up to 12 percent.
