To all with microscopic colitis please be patient. I had this experience and Busesonide. It truly is the answer. It works differently on different people. You need to take two or three every morning for at least two weeks or maybe more. Then take it for a month then slowly taper off if having success. Problem is the constipation side affect needs citrucel to counter react. If you play with the dosage for a month or so then it heals the colon. If watery stools are there in the night then in the morning take the Busesonide. More than one. Do that until stools are firmer. As soon as constipation starts take less and start citrucel. It eventually heals. But it does take patience and persistence. I now take citrucel daily and it helps a lot.
