I'm not going to talk about the Eric Cropp case, since that was a travesty of justice. It is really situational. What gets to the pharmacist is the anxiety and self-doubt that never gets relieved even with legal closure. I used to work in the Office of Health Inspections, Inspector General for my agency (and still keep affiliate membership) and these misadventures happened which there are national committees that deal with peer review. I have seen everything from resumption of normal practice, resignation from a job, surrendering practice, and in three very unfortunate cases, suicide by both immediate and substance abuse means. Oddly enough, my agency does not fire personnel for honest mistakes (they will if a mistake was caused for controllable reasons like malice, lying during credentialing, or being under the influence and to say for some other issues, this agency has no problem firing whistleblowers). However, they have made forced reassignments and practice restrictions.
Absolutely follow what your liability insurance says, the lawyers for both Pharmacist Mutual and the APhA one are practiced. Also, I have probably committed the same mistake you have, but lucked out by either having it caught before harm or in a situation where harm was not the result. That sort of mistake can happen to anyone, and it is a combination of both a practice error and bad circumstantial luck.
It depends on your institution's culture for discipline for the involuntary part of your career fate. Just culture institutions won't get you fired, but will get you sidelined into retraining and administrative work until you resume (or not). Government covers it up, and if not, you just get an SF-50 reassignment to Quality and Performance to fill out paperwork on these incidents in ASISTS for the rest of your career (ironic, isn't it?).
What you need to do is basically acknowledge the misadventure for what it is, take accountability (but don't go out of your way to punish yourself, trust the system for that), and stay the course until this works through the system. If you feel like self-harm/suicide, you do need to get immediate professional help as that doesn't make the situation better for anyone especially yourself. In the cases that I took on, part of the script that comes with the matter is that I advise a practitioner not to act with a guilty conscience until after official action is complete and the practitioner had time to reflect on the process. The only exception was that if they thought that they were driven to distraction by brooding over the incident, in which case we reassigned them to a non-patient care position until psychologically fit to return.
