That the FDA regulate the color of Prescription medication bottles.
I was looking at the differences between several medicine bottles both over the counter and prescription. The problem is that they are all made from the same white plastic bottles, everything from Advil to Zoloft. The same injection molds that make the white plastic bottles could have specific colors added pretty cheaply. Like everything else in the medical community these bottles are white to imply that they are clean and sterile, I get that. But if you picked up a med bottle and it was red you most likely would not accidentally give it to your child. Red for adult only, Purple for antibiotics, Green for pediatric and so on as examples / suggestions. I think this is a very simple change that could potentially save thousands of lives.
