Common Side Effects
Oxybutynin gel has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking
oxybutynin gel were documented and then compared to the side effects that occurred in a similar group of people taking a placebo (a similar gel that does not contain active ingredients).
Based on these studies, the most common bothersome (but not usually dangerous) side effects included:
- Dry mouth -- in up to 7.5 percent of people
- Urinary tract infection (UTI) -- up to 6.9 percent
- Skin reaction (such as redness or irritation) at the application site -- up to 5.4 percent
- Upper respiratory tract infection (such as the common cold) -- up to 5.4 percent
- Dizziness -- up to 2.8 percent
- Fatigue -- up to 2.1 percent
- Gastrointestinal virus (such as the stomach "flu") -- up to 2.1 percent.
It is probable that some of these "side effects," such as the
common cold or a gastrointestinal virus, might be completely unrelated to the medication.
Final Thoughts on Oxybutynin Gel Side Effects
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, your healthcare provider will be able to diagnose and treat the problem.
