Right, as some have said, there are other choices.
And probiotics have done a lot for me.
When I first had UC, the choices were Sulfasalazine, Pred (pill or IV).. and I had some cortifoam in those early years. (If there were steroid enemas I ddn't know.)
Before Rowasa was approved, my GI asked if I'd like to experiment: I mixed up oral sulfasalazine, orange flavored, yet!!
and used a traditional enema bottle to administer it. (This calls for so many jokes.....)
And it was a BIG deal when I could ditch the sulfa and switch to Asacol. So..... from my perspective, we've come a long way in the past 25 years, and research is heading into good directions!
