OAB Treatment Considerations
It's always important to consider the potential side effects of any medication and equally weigh the benefits and risks with your doctor before making a decision.
The most common adverse reactions with BOTOX® treatment are urinary tract infections (UTIs) (18% vs 6% with placebo), dysuria (9% vs 7% with placebo) (painful or difficult urination), and urinary retention (6% vs 0% with placebo) (temporary inability to fully empty the bladder following treatment).
This is not a complete list of possible side effects. Please see the Important Safety Information Including Boxed Warning below, and talk to your doctor about any concerns you may have.
In clinical trials, 6% of 552 patients treated with BOTOX® were temporarily unable to fully empty their bladders on their own after treatment. The temporary inability to fully empty the bladder can be self-managed with a small, portable bladder draining tool, called a self-catheter. This catheter is about the size of a thin straw or coffee stirrer and is small enough to fit in a handbag. It is only inserted when there is a need to empty the bladder and can be used in any restroom. It is important to realize that if this should occur, it is temporary — until the bladder can be emptied on its own. 94% of patients treated with BOTOX® did not have this adverse reaction after treatment.
In general, adverse reactions occur within the first week following injection of BOTOX® and, while generally transient, may have a duration of several months or longer.
