Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Oxybutynin ER (Ditropan XL) and trospium are both used to treat overactive bladder (OAB), but they have some differences. Oxybutynin ER is available in more forms, including tablets, oral liquid, patches, and gel, while trospium is only available as a pill. Both medications can cause dry mouth and constipation, but trospium tends to cause less dry mouth. Oxybutynin ER can be used in children as young as 5 years old, whereas trospium hasn't been studied in children. You need to take trospium on an empty stomach, but you can take oxybutynin ER with or without food. Both medications can cause dizziness and drowsiness.
