Is Botox (botulinum toxin) Classified as Cytotoxic Waste?

The short answer is no. But why do so many people think it is? It’s to do with the concentration of botulinum toxins, which, once they reach a certain level, are classed as cytotoxic; however, no aesthetic clinic will use a concentration that reaches or exceeds the hazardous threshold which is greater than 3%

So, what is the correct way to dispose of Botox? Botox and contaminated vials, needles, etc., should be disposed of in the yellow-lidded sharps bins for medicinally contaminated sharps waste.
