Key takeaways
Oxybutynin (Oxytrol) and vibegron (Gemtesa) are both medications used to treat overactive bladder (OAB). However, they belong to different medication classes. Oxybutynin is an anticholinergic and antimuscarinic medication, while vibegron is a beta-3 adrenergic agonist. Oxybutynin is available in both short-acting and long-acting oral forms, as well as a patch and gel, and can be used in both adults and children. Vibegron is only available as an oral tablet and is not recommended for children. Oxybutynin can cause side effects like dry mouth, dizziness, and constipation, which are more common in older adults. Vibegron has fewer side effects, but can cause headache and cold symptoms. Oxybutynin is available in generic forms, while vibegron is not.
