What are the possible side effects of BOTOX ® Cosmetic?
Many patients experience no side effects from BOTOX® Cosmetic. Bruising at the injection site occasionally occurs and can usually be covered by make-up. Temporary alteration of the position of the eye-brows or temporary drooping of the eyelids can occur with some treatments. Very rarely reported associations have included headache, respiratory infection, flu syndrome, nausea, pain in the face, redness at an injection site, and muscle weakness.
