Anxiety Possible. I have never seen outright panic attacks with oxybutynin. However, increased anxiety and agitation are possible side effects, and some people can have irregularities in their heartbeat. This could result in a picture that looks like a panic attack. If there are concerns about how your or a loved one is tolerating oxybutynin, you will want to contact the prescribing physician.
Yes. While not a common side effect, excitement, nervousness, can occur, especially with higher dosages.
