Bladder control problems: Medications for treating urinary incontinence

Promising new therapies

Researchers are looking into new drugs and therapies, including botulinum toxin type A (Botox).

  • Botulinum toxin type A. Injections of botulinum toxin type A into the bladder muscle may benefit people who have an overactive bladder. Botulinum toxin type A blocks the actions of acetylcholine and paralyzes the bladder muscle.

    Studies have found that botulinum toxin type A significantly improves symptoms of incontinence and causes few side effects. Benefits can last up to nine months. Botulinum toxin type A may be helpful for people who haven't responded to other medications. The Food and Drug Administration (FDA) has not yet approved this drug for incontinence.

    The FDA warns that adverse reactions including respiratory arrest and death may occur following the use of botulinum toxin type A for both approved and unapproved uses.

See your doctor

When talking to your doctor, carefully review all the medications you're taking, including over-the-counter drugs or herbal remedies. Some medications increase bladder control problems. Others may interact with incontinence medications in a way that increases symptoms. Your doctor can help you decide if you need medicine to treat your bladder control problem, and if so, which one may be best for you.
