BOTOX and BOTOX Cosmetic are FDA-approved drugs, and a naturally-derived protein called botulinum toxin. Toxins are naturally occurring substances that at defined doses are capable of causing illness. BOTOX injections are used to correct functional neurologic disorders or for cosmetic reasons. When injected properly with appropriate dosing, the risk of complications is extremely low. However, as with any medical treatment, there is the potential for adverse effects, and therefore, prior to treatment patients must be informed about the potential risks of these treatments.
