There have been no reported cases of a true allergic reaction in nearly 20,000 treatments. People who are known to be allergic to Botulism toxin or albumin should avoid BoTox. A number of neurological and ophthalmologic patients have delivered normal children after receiving their injections. For safety reasons no pregnant or nursing females will be treated. The smallest needles are used and the medicine itself does not sting as much as the usual local anesthetic.
Most patients feel it less than collagen.
Pain can be minimized by the use of ice cooling the skin just prior to injections. Some patients find that two Tylenol tablets before the injections reduce the discomfort. This drooping is a result of the local dissemination of the toxin in the injection site and can be minimized by accurate dosing, as well as proper placement, and keeping the patient in an upright position for three to four hours after injection. If drooping eyelids occur, it is usually minimal and is usually resolved within two weeks. First, do not massage the area of the injection.
