I am a big believer in rectal meds for UP. I also had/have left-sided UC but seems to be confined to rectal area now. When I could not longer take mesalamines and tapering from prednisone my new doctor prescribed rectal meds only while tapering and beyond. He prescribed Cortifoam and Anusol suppositories three times a day. When I ask him for how long - he told me when I felt "normal" but no blood/mucous/diarrhea to back off gradually and then use them for mainteance. I now use both when I feel any symptoms and doing fine since November, 2009.
