About Apriso (mesalamine)

Apriso is a once-daily, extended release, prescription medication used to treat Inflammation in the Colon. It is primarily used for maintaining Remission in adults with Ulcerative Colitis, a type of Inflammatory Bowel Disease (IBD).

5-ASA (Mesalamine), is a long acting version that has an extended release delivery for use in treating Ulcerative Colitis. It is released in the intestines at pH 6 and higher.[1]

It works by decreasing the production of prostaglandins and leukotrienes, chemicals in the lining of the colon that lead to the inflammation of ulcerative colitis. The drug comes in the form of an extended-release capsule and is typically taken once a day. Potential side effects include diarrhea, headache, and nausea.

Apriso can be taken with or without food.

Apriso should NOT be taken with Antacids.

Mesalamine-Induced Acute Intolerance Syndrome
Mesalamine can cause acute intolerance syndrome and the symptoms can be hard to differentiate from the IBD. About 3% of patients are thought to get acute intolerance syndrome. The symptoms may include bloody diarrhea, abdominal pain, cramping, fever, rash, and/or headache. As such, anyone taking Lialda should be closely observed for worsening of these symptoms if they are already present from IBD.

I am currently taking as well the Apriso 4pills 1x/day 1500mg. My CR Surgeon switched me from 2000mg of Sulfasalazine/day. It appears to have less side effects. My final DX is still uncertain, however, labeled Crohns, possibly Crohns/Colitis.
