Amoxicillin is the new and improved version of penicillin that is able to last longer, resist stomach acid, and kill both gram-positive and gram-negative bacteria. It is often used to prevent and treat infections found in cuts and wounds, the mouth, the upper respiratory system, and the bladder. Amoxicillin also has better absorption than another predecessor, Ampicillin.
It is possible for bacteria to build resistance to this drug, as the Staphylococci group of bacteria already has. Amoxicillin may be used in conjunction with clavulanic acid (as in Clavamox) to be effective against Staphylococci as well as other bacteria.
This drug should be given for at least 7-10 days to be effective
