Common Side Effects of Nexium

As with any medicine, there are possible side effects that may occur with Nexium® (esomeprazole magnesium). Yet, not everyone who takes Nexium will have problems. In fact, most people tolerate Nexium well. When people do develop Nexium side effects, they tend to be minor; in most cases, they either require no treatment or can easily be treated by a healthcare professional.
Nexium has been studied extensively in clinical trials, with over 15,000 people worldwide having been evaluated.
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 taking a placebo (a "sugar pill" that does not contain any active ingredients). 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.
The most common side effects of Nexium, occurring in more than 1 percent of patients, were:
* Headache
* Diarrhea
* Nausea
* Flatulence
* Abdominal pain
* Constipation
* Dry mouth.
