For Ulcerative Colitis "I have had colitis for 20 years. I was prescribed steroids but did not want to take them. I had gas, bloating, loose, watery, foul-smelling bowel movements. Up to 20 a day. I started on Asacol 800 mg. I took 6 tabs a day. Two in the morning, 2 midday, and 2 at bedtime. I saw no results and was even passing whole tablets... as I know it is common. I almost threw in the towel. At the 3-month mark, I had formed stools and minimal gas and bloating. You have to be patient. Our bowels did not get sick overnight... so you are not going to be cured overnight. 20 years of issues took about 3 months on Asacol. Now I am down to 2 x 800 mg tabs maintenance dose. 1 tab in the morning and 1 tab at night. I still have the odd loose bowel movement if I eat greasy food or drink too much coffee. But all in all... well worth it."

For Ulcerative Colitis, Maintenance "I have had UC since I was 14 and now 64. Have had numerous flare-ups through this period, but have been very well looked after by consultants and have regular check-ups. Been well for years now, but am now experiencing a bout of I think proctitis, mucus, and wind and running to the toilet. Not due to the consultant for a few months. Started taking Asacol foam enema and am obviously intolerant, as it does not stay in and causes even more mucus. Need to change enemas. Had this now for a few months, need to change to Prednisolone enema. Or has anyone else found something that works well? A call to the consultant is required, I think."

For Ulcerative Colitis, Active "I am taking Asacol for the last 4 years, and I am still having problems with gas and a full stomach, with or without eating or drinking. I am having inflammation in the body, increasing weight, and increasing prolactin (milk), not focusing well, and discomfort."
