BOTOX is exceptionally safe and comes with few risks or side effects. Side effects patients may feel include headaches, bruising, swelling, pain near the injection site, and redness. It typically does not worse than this. Occasionally, patients may experience particularly bad bruising or swelling, though this is usually treatable and temporary.
Risks of BOTOX are even rarer. The main risks of BOTOX are infections, accidental injection into the wrong muscle, or overtreatment. Infections rarely occur, but if they do, antibiotics generally treat them. Overtreatment or treatment of the wrong muscle does not happen often and--like regular BOTOX--will eventually wear off.
Your injector will discuss the possible side effects and risks with you before your BOTOX injections. They will also ensure that you have a low risk of any major risks or side effects.
