Ulcerative Colitis Symptoms

Common active ulcerative colitis symptoms may include:
  • Rectal bleeding
  • Abdominal discomfort/cramping
  • Urgent need to go to the bathroom
  • Bloody diarrhea
The majority of patients diagnosed with ulcerative colitis (UC) in a clinical setting have a mild to moderate form of the condition.

If you have a mild form of the condition, you may experience episodes of diarrhea with no blood or only traces of blood in the stool. If your UC is mild, you most likely won't have night-time bowel movements or rectal incontinence; also, you'll have little or no rectal bleeding.3,4

Those with moderate forms may experience increased stool frequency, more abdominal discomfort, and blood in the stool. If your UC is of moderate severity, you may experience rectal incontinence and have night-time bowel movements.3 Additionally, you may have more rectal bleeding than you would if your UC was mild.

If your ulcerative colitis symptoms change or worsen please contact your doctor.


Asacol (mesalamine) delayed-release tablets, available only by prescription, are indicated to treat mild to moderate flare-ups of ulcerative colitis and maintain remission of ulcerative colitis. Asacol is generally well tolerated. In studies of flare-ups, some people taking Asacol reported headache, abdominal pain, general pain, rash, upset stomach, and worsening of colitis symptoms. In a six month maintenance study, some people reported headache, runny nose, general pain, sore throat, infection, and nervousness. You should not take Asacol if you are allergic to Asacol or to salicylates such as aspirin. Tell your doctor if you have kidney problems or a history of kidney disease. It is recommended that all people have their kidney function tested prior to starting Asacol tablets and periodically while on Asacol therapy. Serious side effects may occur. If you have questions about taking Asacol, please talk to your doctor.
