I have been on Imuran almost two years. Side effects wise...I did have some nausea at first. I was taking it in the mornings but once I switched to the evenings that went away. I do have a lot of fatigue. Not sure whether I can blame that on the Imuran or the UC.
You will also have to have bloodwork taken. I had a lot at the beginning b/c they couldn't get my dosage correct. Now I go every 3/months. It may take awhile to kick in so be prepared for that. It took several months for me. I was also steriod dependent at the time.
Do a search at the top of the page on Imuran. This comes up a lot and you can get some additional information. Keep us posted!
