I'm wondering if anyone who has used Azathioprine (Imuran) has seen a noticeable increase in appetite. I've been using it for 16 days now with a ferret with IBD and her appetite and food consumption have increased quite a bit. I'm concerned about weight gain at this point. Dosage is 1.0 mg once a day, body weight when started was about 1.0 kg.
