There use to be a bit of information on this site concerning the use of oxybutynin in combination... with pseudoephedrine. I do use these meds in combination. Oxybutynin does not work for me without the pseudoephedrine. Please address this issue.

There are no known interactions between oxybutynin and pseudoephedrine. However, it does not mean that no interactions exist, so if you do experience any odd symptoms please see your doctor.
It is interesting though that oxybutynin doesn't work without pseudoephedrine for you.
