Oxybutynin Side Effects

You should notify your healthcare provider if you experience severe constipation, hallucinations, or difficulty passing urine while taking oxybutynin. Side effects of the medication, however, are generally minor and don't typically require medical attention. The most common side effects of oxybutynin that were seen in clinical studies included dry mouth, dizziness, constipation, and drowsiness.

 

An Introduction to Oxybutynin Side Effects

As with any medicine, side effects are possible with oxybutynin chloride (Ditropan®); however, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
