The wait time given is not always the time it takes to fill YOUR prescription. It's usually the time it'll take to finish everyone else's prescription that came before yours.Your prescription has to be entered EXACTLY the way the doctor wrote it. If someone, such as an assistant, enters the prescription incorrectly but doesn't notice until the pharmacist checks it for accuracy and appropriatenes, the process gets restarted. The prescription gets sent back for someone to cancel it in the computer and re-enter everything once again. If you go to a pharmacy with inexperienced staff, lots of mistakes are made behind the counter, but the pharmacist has the final check. Trust me, there's a lot that can go wrong and can be missed if the pharmacist is rushed and stressed out.For instance, I used to work at a VERY busy pharmacy. We even had a huge room sized robot that counted and labeled the majority of our prescriptions. This would seem like it would make it super easy to work there. But, in fact, sometimes it made it even more dangerous for patients. Anyway, on a very busy day, the pharmacist made an error and didn't open up the box of they were checking. Just so happens that 100microgram patches were put in a 25 microgram box. That's 4 times the dose that the patient used to receive. The patches look all the same except for the box and the size of the patch and maybe some writing but when you've been on these meds for a long time most people won't even think to read the package each time they apply the patch to their skin.We got a frantic call from the patients wife who, upon trying to wake him, she was unsuccessful. She called to inquire if the doctor changed his doseu2022 That's when the pharmacist asked her to read the patch off his arm. This pharmacist was mortified that they had made such a huge error. It ruined them for a long while. Luckily, the patient survived. But, those mistakes stick with you forever. They're always on their minds when they are working and sadly even when they aren't.So when you wonder what takes so long to prepare a prescription, please be nice about wait times, you really don't know what the pharmacist has just gone through and they may just want to take their time so nobody gets hurt.
