What are some common side effects of BOTOX® injections?
A. Some patients notice redness or swelling at the injection sites which goes away within a day. Others have a mild tingling or numbness for a few days after their BOTOX® cosmetic session. BOTOX® injections will sometimes cause minor drooping of the eyelid or eyebrow in the affected site, but this is a rare and temporary effect that vanishes within a week or two. There is also the potential for a reaction to the BOTOX® cosmetic itself, which can produce mild flu-like symptoms, headaches, and nausea.
