About

What is solifenacin?

Solifenacin is a prescription drug. It comes as an oral tablet.

Solifenacin is available only as the brand-name drug VESIcare. It’s not available as a generic drug.

Why it's used

Solifenacin is used to treat symptoms of overactive bladder. 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

This drug 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.

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 overactive bladder, your muscles contract before your bladder fully expands, which causes frequent urges to urinate. This drug works to interact with chemicals in your body that cause the bladder muscles to contract. This decreases your sudden need to urinate, having to urinate often, and leaking in between bathroom visits.
