Hi Amywaffle,
Have you been on any other meds besides Pred? Pred is usually a last resort for a UC sufferer.
I take Imuran have you tried this med yet. Its worked for me. No blood in 3 yrs. I still have flare ups but Its better than being on Pred.
There are tons of other meds to try and medicated enema's.
I hope you find the right combo to make you feel somewhat better.
Hang in there ok
