Colitis Home > Delzicol Side Effects

Sore throat, belching, and abdominal (stomach) pain are some of the most commonly reported side effects of Delzicol. It can be difficult to predict, however, if you will experience problems, so make sure to report anything out of the ordinary to your healthcare provider. Serious reactions (such as depression, decreased urination, and difficulty breathing) can also occur, and will require medical attention.


An Introduction to Delzicol Side Effects

As with any medicine, Delzicol® (mesalamine) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in many cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Delzicol. Your healthcare provider can discuss a more complete list with you.)

Common Side Effects With Delzicol

Delzicol was approved based on studies involving the tablet formulation, which was sold under the name Asacol®.
Asacol has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were documented and then compared to the side effects that occurred in another group of people not taking the medicine. As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the group not taking the medicine.
In these studies, some of the most common Asacol side effects included:
  • Abdominal (stomach) pain -- in up to 18 percent of people
  • Belching -- up to 16 percent
  • Pain -- up to 14 percent
  • A sore throat -- up to 11 percent
  • Back pain -- up to 7 percent
  • Joint pain -- up to 5 percent
  • Muscle tension -- up to 5 percent
  • Vomiting -- up to 5 percent
  • Constipation -- up to 5 percent.
Other common side effects, occurring in 2 percent to 3 percent of people, included:
