Its not that common, it doesn't happen to every guy and it is a big deal!
Wait, wrong topic.
Its not a big deal, its a mistake, they happen. The liklihood of harm is minimal, all you have to do is admit the mistake, learn from it and move on. Not all medication errors are 'big deals'.
I once gave an Adcal D3 to a patient by mistake, I admitted my error, learnt from it and then moved on. Thankfully my manager used common sense and obviously gave me a letter on file but did not start alarming me by making a big song and dance of it.
There will always be those who want to use the scare tactic of blowing things out of proportion, all med errors are important to highlight, but no, they're not all big deals.
