I think you should complain, if for no other reason than that it might make a difference for someone else down the line.

I was shorted once on one of my meds, but since I didn't catch the mistake until a few days later, I never bothered to complain. I just took less than I was supposed to for a few days to make up the difference. Ever since then I've felt bad that I never said anything to the pharmacist about it.

It's so easy to get yourself labeled when you complain about your narcotics, even when you're in the right. One time my doc accidentally prescribed me a twenty-five day supply intead of the usual thirty. He wrote out a hundred, and I was taking them four times a day. When I showed up back at the office twenty-five days later, I was given a lecture on narcotic addiction, along with a hefty amount of paperwork. It took a lot of work to get that corrected in my file.
