I always leave 1/3 in the bottle(it's all I CAN do without bringing it all back up), and my tests have always been fine.
Ulcerative proctitis. On Asacol 3 3x a day, and
Meslamine enemas nightly.
Now on Hydrocortisone suppositories for 2 weeks
Doc now has me on prescription Pepcid, and Questran. Just started that 05/15, so will wait and see.
Urgency is still my biggest problem, and extreme gas. Blood is now gone.
