I posted a few minutes ago reading the pill wrong. After finding several more, I realized I misread the number. If anyone could help me identify a round peach pill with the markings PLIVA on one side and 563 on the other, it would be greatly appreciated!
Cyclobenzaprine 10mg HCl tablet. It's a muscle relaxant, there is a image of it in this website's domestic drug images on page 9.
