Is there any danger of botulism from Botox injections?
No. Botulism occurs when large amounts of botulinum toxin are ingested into the system, usually from eating contaminated food. Doses of about 3,000 units are considered highly toxic. There are 100 Units of Botulinum toxin per vial. That means it would require the full contents of 30 vials to be injected at one sitting to cause botulism. The amount of Botox given during a typical cosmetic injection is too small to give a healthy patient a botulism-like illness. During a Botox cosmetic procedure patients receive about 10-200 units. Once injected into the body, the toxin is rapidly broken down (within hours!), so levels of toxin do not build up over time with subsequent injections. Given by trained physicians in the correct amount there is no danger of botulism from Botox.
