Ampicillin is one of the most widely prescribed antibiotics.
It is considered a penicillin and is a close relative of another penicillin,
amoxicillin. Unlike penicillin, ampicillin and amoxicillin can penetrate and
prevent the growth of certain types of bacteria, called gram-negative bacteria.
Ampicillin is used mainly to treat infections of the middle ear, sinuses,
bladder, kidney, and uncomplicated gonorrhea. Ampicillin also is used
intravenously to treat meningitis and other serious infections.
