Why it’s used
Solifenacin is used to treat symptoms of overactive bladder (OAB). These symptoms include:
- a strong need to urinate with leaking or wetting accidents
- a strong need to urinate right away
- urinating more often than usual
How it works
Solifenacin belongs to a class of drugs called urinary antagonists. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.
Normally, when your bladder fills with urine, it expands. Once it’s fully expanded, it sends a message to your brain telling it you’re ready to urinate. When you urinate, the muscles in your bladder contract, which starts a flow of urine.
When you have OAB, your muscles contract before your bladder fully expands, which causes frequent urges to urinate. Solifenacin works by stopping sudden bladder muscle contractions and increasing the amount of urine that your bladder can hold. This helps to control the release of urine and helps reduce your symptoms.
