I am currently on 4800mg of asacol. Last year i got C-Diff due to a few doctors neglagence and them prescribing me a zpack with little regard to the fact that i have UC. After a long battle and hosplitalization with that, this year my allergies have been insane.
I have used the neti pot (w/sinus rinse packets), steam showers,claritin and afrin in moderation. I have been doing this since january. it has worked very well and i have fought off any sinus infections using this method.
But, the reason I am posting in reply to this, is I read something this weekend that says that by using probiotics regulary will help with allergy problems.
One of the things I learned from having c-diff was how important it is to regulary take (real/good) probiotics if you have UC.
that is my 2 cents, if you are interested in the article I read on probiotics, pm me or post, and i will supply the link.
