What are the risks of BOTOX® Cosmetic injections?
The most common side effects are headache, respiratory infection, flu-like syndrome, temporary eyelid droop, and nausea. Less frequently occurring (<3%) adverse reactions include pain in the face, injection site redness, and muscle weakness. These events are thought to be associated with the injection and occurred within the first week. BOTOX® Cosmetic can’t be used if there is an infection at the proposed injection site(s) or in individuals with known hypersensitivity (allergy) to any ingredient in the formulation (i.e. the milk protein Casein). Patients with neuromuscular disorders like Myasthenia Gravis and Eaton Lambert Syndrome may be at increased risk of clinically significant systemic effects from typical doses of BOTOX® Cosmetic.
