Is botox safe when you have malignant hyperthermia?

Halothane is an anesthetic. I haven't heard of this being used in years. As far as I'm aware there isn't any of this in Botox, and shouldn't be any in topical numbing creams used prior to some procedures, but to be certain, you should contact Allergan at 800-433-8871, who makes Botox, and ask them. And opt for no numbing cream prior to injections. "This answer has been solicited without seeing this patient and cannot
