Imuran is definitely weight dependant. I forgot the actual conversion but if you look up Imuran from a doc's point of view there is max weight dosage. Many GI docs will start at that dosage and work their way down. I beleive the dosage is 1-2 mg/kg. So if a man weighs 200 lbs. Approximately that weight is 100 kg so the max that person can take is roughlyy 200 mg for treating UC. Obviously for different conditions there are different ranges. Also doc use Imuran sometimes as an adjunct med not the primary med. So one will sometimes see people on daily 5 ASA meds with 50 mg of Imuran. The Imuran is just keeping things in check.
I myself started at 200 mg and that's where the doc wanted me. I weighed 187 lbs at the time. I got him to lower it to 150 mg and I am hoping to lower it to 100 mg this spring.
I hope this helps.
