OnabotulinumtoxinA, namely Botox, is a protein from the bacteria that cause botulism illness. Used in small doses directly injected into bladder tissues, this protein partially paralyzes muscles.
Clinical research shows that it may be useful for severe urge incontinence. The temporary effects generally last five months or more, but repeat injections are necessary.
About half of people had side effects from these injections, including 9 percent who had urinary retention. So, if you're considering Botox treatments, you should be willing and able to catheterize yourself if urinary retention occurs.
Key word: overactive bladder injections
