Many, many years ago, I had a sinus infection and the first prescription did not totally clear it up. I called the pharmacy and ordered a refill, (which I was entitled to) picked it up and went back home. The next morning I opened the bottle and the pills were a different color, so I called the pharmacy. They had given me someone else's medicine, which was for birth control. They quickly called the other lady; all I can say is "I hope she didn't get pregnant!!"
