What are the potential complications associated with Botox and how common are they?
First we need to differentiate the complications listed on the package insert which are available for review on the Botox website and are numerous and the likely complications that are due to Botox. The complications that are listed on the package insert are all the possible complaints patients in the initial study experienced when being injected with Botox whether or not the complaint was a direct result of the Botox or not. Ie. A patient developed a fever or cough after in injection, likely not due to the Botox, but still reportable. You should still review the website for a complete list of potential complications. The complications that are more likely to be associated with Botox are rare, but include, infection, bleeding, bruising, affect of a muscle group that was not intended such as the upper eyelid, tenderness and redness at the injection sight. Other than a slight bruise at times and temporary redness and tenderness at the injection sight the other complications are rare.
