Maybe it boils down to your expectations as well and that your doctor isn't clear on what they may be.
You could try the other 5ASA meds, both oral and rectal you could consider to try the enemas instead of just the suppositories.
Asacol is a base-line med....but not all docs use it as such...some use pred...to which I think screws up the future potential of some patients' progress or success with 5ASA meds.
Where exactly is your UC? what exactly are your symptoms that you're having at this point in time. I know I've asked you but I don't remember....
I'd be somewhat afraid to graduate to the immunosuppressants as well...but I have success with the meds I'm on...but things can change as they have for others and I dread the day that it may happen they don't work any longer.
*Heather* Status: mild flare enemas tapered to every 3rd night
~diagnosed January 1989 UC (proctosigmoiditis)
~UC meds: Asacol (3 x2 daily); Salofalk enemas nightly for flares & taper to maintenance
~Bentylol (dicyclomine) 20mg as needed; Ranitidine (reflux); Effexor XR 75mg(depression); Pulmicort/Airomir (asthma)
~vitamins/minerals/supplements; Probiotics....(Natural Factors Protec, Primadophilus Reuteri Pearls). @ bedtime
~various digestive enzymes as needed
~URSO for PSC (or PBC) 500mg X 2 daily (LFTs back to NORMAL!!)
My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
