BOTOX is generally safe, but like all medications, it can cause side effects. Some of
these may be serious and even life-threatening.

Get Medical Help Right Away If You Experience:
These problems may happen hours to weeks after your injection:
● Trouble swallowing, speaking, or breathing (especially if you’ve had these issues before)
● Muscle weakness throughout your body
● Blurry or double vision
● Droopy eyelids or eyebrows
● Hoarse voice or changes in your voice
● Trouble clearly speaking
● Loss of bladder control

These symptoms could mean the effects of BOTOX have spread beyond the injection site. While this is rare, it’s important to be aware.
Note: There have been no confirmed serious cases of this happening when BOTOX is used at the recommended dose for chronic migraine.
