What is Solifenacin? Solifenacin (trade name Vesicare) belongs to the family of medications known as antispasmodics. It is used to relieve symptoms associated with an overactive bladder, such as urinary urgency (a need to urinate right away), urinary frequency, and urge incontinence (leaking or wetting caused by an unstoppable urge to urinate).
