Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Vibegron (Gemtesa) and tolterodine (Detrol) are both medications used to treat overactive bladder (OAB). However, they belong to different medication classes. Vibegron is a beta-3 adrenergic agonist, while tolterodine is an anticholinergic medication, also known as a urinary antispasmodic. Vibegron is taken as a 75 mg tablet once daily, whereas tolterodine is available in both immediate-release and extended-release forms (Detrol LA), with dosing varying from 1 mg to 4 mg per day. Vibegron is only available as a brand-name medication, while tolterodine is available in both brand-name and generic forms. Common side effects of vibegron include headache and cold symptoms, while tolterodine can cause dry mouth, headache, and dizziness. Vibegron can be taken with anticholinergics, but tolterodine should not be combined with other anticholinergic medications due to increased risk of side effects. Additionally, tolterodine may cause memory problems and is linked to a higher risk of dementia, which is not a significant concern with vibegron.
