You've finally reached the end of the line in retail. You've had enough of the rude public, the non-pharmacist managers, and the corporate cuts. You are ready to have an hour lunch (maybe) and normal bathroom breaks. You are ready to feel a little more professional. Sorry, retail pharmacists, you know it's true. Yes, you probably make more money than me, but at least I'm not worried about my health. (I was working retail in a terrible part of town. All of the good areas were full with waiting lists of pharmacists ready to transfer out just like me. I just chose a quicker path). The first thing that is entering your mind as I'm noticing on a couple of comments here is that you think a special amount of training is required. Let's first think about hospital pharmacy. You can transfer from retail to hospital pharmacy fairly easily. Hospitals can train you. There is a lot to learn, yes, but I was up-to-speed in two months. I worked five years in retail, if that helps at all.
You will have to learn about the hospital's formulary, allergy list, and perhaps coumadin and pharmacokinetic dosing again. You will certainly have a lot of pharmacists willing to help. There will be no more jerks in line waiting on you to hand them their papersack with drugs; you will merely have a function to be a part of the team that helps to heal the acutely and chronically ill. You will revisit sterile technique to mix IVs, chemo, and TPN. (I hope, though it seems the hospitals I worked in didn't observe this at all!)
And most importantly... you will have a life back. No more driving home from work in retail and a customer follow you home. No more jerks waiting until 3 minutes before close to get 10 prescriptions filled... all new.
I don't regret leaving retail at all. I do regret losing the knowledge of some of the new drugs since graduation, but it's worth it for peace of mind and life.
I hope that helps.
