No, Purell Does Not Breed Super-Anything

Recently, I was sitting in a meeting and reached for the dispenser of Purell hand sanitizer sitting on the conference room table. A colleague of mine gave a small, rueful shake of her head to the person on her other side. Apparently I had erred. I asked what was the matter, and got a brief answer to the effect of “because superbugs.” We exchanged nothing more about it; the interaction was over before the alcohol had dried from my hands.

I wouldn’t have thought anything of such an interaction with anyone else, but my colleague is a PhD student in immunology, six years older and more schooled than I, doing her doctoral research in a lab run by a physician-scientist — a specialist in infectious disease, no less. A touch ironic.

Despite this, very few are able to live up to their promise. In most cases, particularly where children are concerned, the side effects of these medicines can be worse than the symptoms they are intended to treat. Because I am a pediatrician, and because the evidence for cough and cold medicines (I will refer to them here as CCMs) for children is particularly absent and because adverse events due to CCMs are most frequently seen in children, I will focus mainly on this population.
