Colitis Home > Lialda Side Effects
For those who are taking Lialda, side effects that may occur include headache and gas. Problems such as back pain, shakiness, or fatigue are less common but may still occur. Some side effects of Lialda are potentially serious and should be reported to a healthcare provider right away. These include high blood pressure, decreased urination, worsening of ulcerative colitis symptoms, and signs of an allergic reaction.
As with any medicine, side effects are possible with Lialda® (mesalamine); however, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Lialda. Your healthcare provider can discuss a more complete list of Lialda side effects with you.)
Lialda has been studied thoroughly in clinical trials, in which a group of people taking the drug have side effects documented and compared to another group not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies that used a placebo, the most common Lialda side effects included:
- Headaches -- in up to 5.6 percent of people
- Gas -- up to 4 percent
- Abnormal liver function tests (found using a blood test) -- up to 2.2 percent.
Some studies did not use a placebo; instead, everyone in the study was treated with Lialda. In these studies, there is really no way to know for sure if the reported problems are really side effects at all. In these studies that did not use a placebo, the most commonly reported Lialda side effects included but were not limited to:
- Ulcerative colitis in people who had been symptom-free
- Abnormal liver function tests
- Stomach pain (abdominal pain)
- Abdominal bloating.
