Merck Consumer announced that Oxytrol for Women (oxybutynin transdermal system) is now available over-the-counter (OTC) to treat women with an overactive bladder.

Oxytrol for Women is an antispasmodic/anticholinergic indicated to treat symptoms of bladder instability associated with voiding in patients with uninhibited neurogenic or reflex neurogenic bladder (eg, urinary urgency, frequency, leakage, urge incontinence).

The FDA approved the Rx-to-OTC switch on January 25, 2013.  The FDA considers this a partial switch, as Oxytrol will remain available by prescription only for the treatment of overactive bladder in men. 

Each Oxytrol for Women patch delivers 3.9mg oxybutynin per day for four continuous days.  The patches will be available in 4-count boxes.
