Dexlansoprazole has been studied extensively in clinical trials. In these studies, side effects occurring in the group of people taking dexlansoprazole were documented and compared to the side effects that occur in a similar group of people taking either a placebo (a "sugar pill" with no active ingredients) or a similar medication,
lansoprazole (
Prevacid®).
Based on these studies, the most common bothersome (but usually not dangerous) dexlansoprazole side effects included:
- Diarrhea -- in up to 5.1 percent of people
- Abdominal pain (stomach pain) -- up to 4 percent
- Nausea -- up to 3.3 percent
- Upper respiratory tract infection (such as the common cold) -- up to 2.9 percent
- Gas -- up to 2.6 percent
- Vomiting -- up to 2.2 percent.
Other Uncommon Side Effects of Dexlansoprazole
Other uncommon side effects (occurring in less than 2 percent of people) were also reported in clinical studies. Given how uncommon they are, it can be difficult to tell whether these side effects are actually caused by the medication itself or by something else.
Some of these rare but possible side effects include, but are not limited to:
You may experience some or none of the side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking the drug or if something "just does not seem right." While it may not be a side effect of dexlansoprazole, your healthcare provider will be able to diagnose and treat the problem.
