I'm busy so I didn't read the paper - is there a reason to use neosporin instead of petroleum jelly? In addition to your concern, many people are actively allergic to the ingredients in neosporin.
yes, really, don't do it. it's a danger not only to yourself, but to others as well.
You think putting neosporin in your nose a few times will get someone infected with antibiotic resistant staph?
Not one individual, but if millions of people do it across the population...
Millions of people already do it across the population.
