There are several prescription drugs for overactive bladder (OAB).
The FDA approved medications, or drugs, currently available on the U.S. market for the treatment of urinary incontinence are for a specific condition called overactive bladder (OAB). Some are also used for OAB with urge urinary incontinence (UUI). You may have seen advertisements on television or in magazines for these medications. Most of the prescription drugs for OAB partially calm the bladder muscles that cause abnormal contractions, thereby reducing the frequency and severity of the overwhelming urge to urinate. Some of these drugs may also increase the bladder’s capacity to hold urine and delay the initial urge to void. This class of drugs is referred to as antimuscarinics.
