Vesicare (Solifenacin) – Oral

What Is Vesicare?

Vesicare (solifenacin) is a prescription drug used to treat a chronic condition called overactive bladder (OAB). The Food and Drug Administration (FDA) approved it for use in people aged 2 years and older.

Solifenacin belongs to a class of medications called anticholinergics. It works by blocking specific receptors in your body, causing your bladder to relax. It reduces bladder spasms and the urge to frequently urinate.

Vesicare is available as an oral suspension and tablets.

What Is Vesicare Used For?

The FDA approved Vesicare to treat OAB in adults with symptoms of urge urinary incontinence, urgency, and urinary frequency.

OAB occurs when the bladder muscles start to contract involuntarily, even when you don’t have much urine in your bladder. These contractions cause a sudden urge to urinate and may lead to incontinence (involuntary loss of urine).

Vesicare also treats a bladder problem known as neurogenic detrusor overactivity (NDO) in children.

How to Take Vesicare

Vesicare comes in two forms: tablet and oral suspension. Adults with overactive bladder will be prescribed the tablets, whereas the oral suspension formulation is indicated for children with NDO.


Swallow the tablet whole with a drink of water. Do not crush or chew. You can take your dose with or without food.

Oral Suspension

To take the oral suspension:
