Toviaz (Fesoterodine Fumarate) is a medication prescribed for treating a bladder condition called overactive bladder with symptoms such as urge incontinence, urinary urgency, and urinary frequency.

The medication can also be used to treat neurogenic detrusor overactivity in children below the age of 6 years weighing 25kg and above. Toviaz is a type of extended-release tablet that contains fesoterodine fumarate as its active ingredient.

Toviaz inhibits Muscarinic receptors in the bladder. By blocking these receptors, the medication reduces the urgency and frequency of urination associated with overactive bladder.

This medication also helps to control involuntary contractions in your bladder that cause symptoms such as urge urinary incontinence, urinary urgency, and urinary frequency.
