Table of contents:

Toviaz is a prescription medication used to treat symptoms of overactive bladder. Toviaz is a medication containing the active substance fesoterodine. Fesoterodine belongs to the class of drugs called urinary antispasmodics. It works by blocking certain receptors in the bladder, thus reducing spasms, and decreasing the urge to urinate.

Fesoterodine Fumarate comes in prolonged-release tablet form with strengths of 4 mg and 8 mg. It is used to treat overactive bladder with symptoms of urinary frequency, urgency, and incontinence in adults. Antispasmodics, such as fesoterodine, block the action of acetylcholine, a neurotransmitter that plays a role in bladder contractions. By blocking acetylcholine, fesoterodine reduces these involuntary contractions and improves bladder control.

Uses and Dosage

Toviaz (fesoterodine) is an oral tablet that should be taken once a day, with or without food, according to your doctor's instructions. Each dose should be taken with a full glass of liquid. Do not crush or chew Prolonged Release Tablet, as this can cause all the drug to be released at once, increasing the risk of side effects. Do not split tablets unless there is a score line on them, and your doctor or pharmacist has advised you to do so. Always swallow whole or split tablets without crushing or chewing.
