I was on pred for about 6 weeks and tapered down from 40mg to 5mg. Moonface went away 2 weeks after the final dose.
I agree with Tab, avoid salt.
Rio, 31 yr old male - diagnosed with UC in 07/2006.
Alternative therapies for several months (SCD, ayurvedic treatments, chinese herbs, VSL#3): didn't work and became anaemic.
Canasa, 2 daily: remission for a month then flared up.
Completed first (6-week) tapered course of Pred in 10/07, flaring up since coming off it.
Currently on: 4800mg Asacol (6 x 400mg, twice a day) & Aloe Elite (not sure if it works).
Holding off from taking next dose of Pred as the side-effects were strong, but may have to give in if I'm not better soon.
