Are botulinum toxin injections safe?
Botulinum toxin is made by the same bacterium that causes food poisoning. A high dose of botulinum toxin could be fatal, just as food poisoning can be fatal. However, the dose given in injections is so small that it’s unlikely you’ll have any harmful effects from the toxin. Botulinum toxin has been used safely in thousands of people for more than 10 years.
