Fentanyl Patch Side Effects
Common Side EffectsThe fentanyl patch has been studied extensively in clinical trials with children and adults. In these studies, the side effects that occurred in a group of people using the patches were carefully documented. As a result, it was possible to see what side effects occurred and how often they appeared.
The most common side effects of fentanyl patches, occurring in more than 10 percent of people in clinical trials, included:
- Dry mouth
Other common fentanyl patch side effects, occurring in 3 to 10 percent of people, included:
- Abdominal (stomach) pain
- Flu-like symptoms (such as fever, aches, and chills)

Final ThoughtsYou 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 problems with a medicine that you have never tried.
