Hi..welcome to the forum!
I've never been on Imuran, so I cannot help you with that. It probably would be best to cal the doc and get off the Imuran.
Have you tried any rectal meds? They do come in 5ASA (like Asacol) or in steroid...both topical.
Something to consider if you've never used them and if you don't want to continue the immunosuppressant route.
Have you had an upper gastroscopy done to rule out any other problems that could cause you vomiting?
I hope others will be able to share their experiences with imuran and nausea.
*Heather* Status..Asacol 6 (3 twice daily); enemas every 5th night
~diagnosed January 1989 UC (proctosigmoiditis)
~Bentylol (dicyclomine) 20mg as needed
~Probiotics....(Natural Factors Protec, Primadophilus Reuteri Pearls, Natural Factors Ultimate)....1 each @ bedtime
~various digestive enzymes as needed
~Ranitidine (reflux); Effexor XR 75mg(depression); Pulmicort/Airomir (asthma)
~URSO for PSC (or PBC) 500mg X 2 daily (LFTs back to NORMAL!!)
My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
