PredniSONE and doctor check

My husband has been diagnosed with Ulcerative Colitis. He is only 37 years old and has lived a very healthy life so far. Two weeks ago he started showing colitis symptoms and between Monday, Jan. 29 to Wed. Feb. 7 (9 days!) he lost 28 pounds! He was given a shot of Prednisone in the ER and prescribed a short regime for it with a gradual decline to ween him off of it as soon as possible. He seems to have the worst and oddest side effects. Has anyone ever experienced this with Prednisone...He slurrs his speech, drools almost constantly, has trouble swallowing, and his face from the upper lip down looks like his face is hanging there. (I had his doctor check for stroke and there was none.) That on top of the nausea, vomitting, dizziness, weakness, and being constantly sleepy. I know it all sounds real bad but he has actually improved since taking the prednisone. At least he's alive and getting better. Hope this helps.
