Gemtesa is a prescription medication used to treat overactive bladder (OAB) with symptoms such as urgency, frequent urination, and urge incontinence. Its active ingredient, vibegron, is a β3-adrenergic receptor agonist that helps relax bladder muscles so the bladder can store more urine without sudden contractions.
Unlike some older OAB medicines, Gemtesa is not an anticholinergic, so it may cause fewer dry mouth or constipation side effects. Gemtesa comes as an oral tablet and can be taken once daily, with or without food.
In this easy-to-follow guide, you’ll learn what Gemtesa is, how it works, when doctors prescribe it, how treatment is given, possible side effects, safety tips, and answers to the most-searched questions (dosage, cost, generics, insurance, alternatives, and more).

What Is Gemtesa?
- Brand name: Gemtesa
- Generic name: Vibegron
- Drug type: β3-adrenergic receptor agonist
- Form: 75 mg oral tablet
Gemtesa is approved for adults with overactive bladder who experience urgency, frequency, or leakage. It can be taken alone or alongside other supportive therapies.
How Does Gemtesa Work?
Normally, the bladder muscle contracts too often in people with OAB, causing urgency and leaks. Gemtesa:
- Activates β3 receptors in the bladder wall.
- Relaxes bladder muscles to increase storage capacity.
- Reduces sudden or involuntary bladder contractions.
This makes it easier to hold urine longer and reduces urgency episodes.
