🚨 Benzonatate can kill—but rarely by accident. In our 20-year review, serious toxicity (seizure, dysrhythmia, death) occurred almost entirely in intentional cases. Unintentional? Nearly all walked away.

Since it appears impossible to get people to stop saying Poison “Control” Center can we at least call it a Poison “Command” Center?
We don’t command or control anything but maybe I could get a cool badge that way.

I have to correct text messages to my wife from "Ok" to "Kk" because for some reason I read "Ok" as more of a "I will tolerate this" and Kk is a positive affirmation of plan. How crazy is this?
