I have been taking augmentin(4 tablets out of a prescribed 20), and have developed a reddish colored rash on the left side of my face, as well as the center portion of my forehead. I realize that this is one of the potential side effects of this drug, but I would like to know what enters into play to cause this, and is OK to continue taking full amount of 20, or should I cease taking them? My email address is YYYY@YYYY Thank you.
