You will not likely have any side effects (such as increased appetite) from the steroid foam. That's the great thing about
it-- besides ease of application & relief of low end symptoms.
Steroid side effects kick in within a few weeks on Prednisone, but take longer to show up if one uses the hydrocortisone enemas-- because less steroid is absorbed systemically. I cannot comment on budesonide enemas, having never used them, but they are supposed to be less problematic than hydrocortisone from the standpoint of systemic side effects. Hopefully, you'll continue doing well on the present regimen & not have to move up to the liquid retention enemas so this info will be just a store-away. Keep us posted on your situation, eh? /Old Hat (nearly 30 yrs with left-sided UC ... [etc.])
