Didn't you get a mid-term evaluation? Did she give you a fair warning then? I feel like there's a lot of critical details that you are probably not telling us. Anyways, P4 here, it's really hard to fail an APPE rotation so you should take a step back and analyze the situation. What went wrong (was it you or the preceptor or perhaps both)? Pharmacy is a small world, if I were in your shoes, throwing around lawsuits or pointing fingers for HIPPA violations will not do you, your school, or anyone any good. Collect yourself, present your case to your APPE coordinator, and be very professional about it. If you encounter resistance, politely work your way up the chain of command. If you have the right attitude, it'll work out. I hope they will let you make up the rotation.
