Using Botox for Overactive Bladder
Botox is also approved for treating an overactive bladder in adults. It is approved for use only in people who have already tried anticholinergic medications for overactive bladder
treatment and who found the medications to be ineffective, unsafe, or intolerable. In studies, Botox worked for about 24 weeks, on average, which means you should expect to need about two treatments per year, although some people need them more or less frequently.
How Does Botox Work?
Botox is a toxin produced by Clostridium botulinum
bacteria. The drug works by decreasing nerve signals that are sent to muscles, which causes the muscles to relax. Botox enters nerve cells and inhibits the release of acetylcholine, a chemical that transmits signals from nerve to nerve. The actions of the drug are not permanent, and the muscle will eventually recover and return to its previous state.
For severe sweating, Botox works similarly, blocking the release of acetylcholine from the nerve cells that stimulate the sweat glands.
