Asacol (mesalamine delayed-release tablets) tablets are indicated for the treatment of mildly to moderately active ulcerative colitis and for the maintenance of remission of ulcerative colitis.
Take this medicine exactly as directed by your doctor. Do not take it more often, and do not take it for a longer time than your doctor ordered. Also, do not stop taking this medicine without first checking with your doctor.
Keep taking this medicine for the full time of treatment, even if you begin to feel better after a few days. Do not miss any doses.
You should take the delayed-release tablets with food. All other brands of capsules and tablets can be taken with or without food.
Swallow the capsule or tablet whole. Do not open, break, crush, or chew it before swallowing.
Do not change to another brand without checking with your doctor. The number of capsules or tablets that you take depends on the brand and strength of the medicine. If you refill your medicine and it looks different, check with your pharmacist. One tablet of Asacol® HD 800 milligrams (mg) tablet may not work the same way as two Asacol® 400 mg tablets.
If you are taking the extended-release capsule or the delayed-release tablet, part of the capsule or tablet may pass into your stool after your body has absorbed the medicine. This is normal and nothing to worry about.
If you miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Asacol (mesalamine delayed-release tablets) tablets are contraindicated in patients with hypersensitivity to salicylates or to any of the components of the Asacol (mesalamine delayed-release tablets) tablet.
Patients with pyloric stenosis may have prolonged gastric retention of Asacol tablets which could delay release of mesalamine in the colon.
Exacerbation of the symptoms of colitis has been reported in 3% of Asacol (mesalamine delayed-release tablets) -treated patients in controlled clinical trials. This acute reaction, characterized by cramping, abdominal pain, bloody diarrhea, and occasionally by fever, headache, malaise, pruritus, rash, and conjunctivitis, has been reported after the initiation of Asacol tablets as well as other mesalamine products.
