At the news article’s website, someone speculated that her insulin bottles, which are far smaller than the maximum size liquid container permitted as carry on luggage, possibly lacked prescription labels. What percentage of Americans need injectable insulin? Any doctors know? This can’t be a new issue. Even the dork thug could have clued her in to the proper protocol for carrying medications rather than being a gratuitous bully about it.
The prescription labels are on the box, not the bottles. The labels are too big to fit directly on the vial.
Second, all insulin carry packs I am aware of do not accommodate the box. Carry packs can hold the glucose meter, a syringe or two, test strips and the vial.
Most diabetics use insulin pens these days. No prescription label on those. I've never had a problem getting them through at an airport.
