How does this medication work? What will it do for me?
Cefprozil is an antibiotic that belongs to the family of medications known as cephalosporins. It is used to treat certain types of infections caused by bacteria. It is most commonly used to treat infections of the throat, ear, sinus, skin, and bladder. It works by weakening the cell walls of the bacteria causing the infection, thereby killing the bacteria.
