An infected wound is marked by pain and swelling. The presence of bacteria on the tissues prevents wound healing from starting. If the bacteria enter the bloodstream, it can trigger a severe case of infection or sepsis.

The antibiotic that is given is dependent on the strain of bacteria that is present. Depending on the drug chosen by the doctor, it might be the oral variant or given intravenously.

Widely used antibiotics for an infected wound


Amoxicillin is included in the penicillin group of beta-lactam antibiotics. It focuses on the bacterial population and not effective for non-bacterial infections.

As a member of the penicillin group, it does not eliminate the bacteria directly but destroys the cell wall, thus preventing it from producing proteins which are necessary for them to survive and thrive.

This drug is ideal if the infected wound is brought about by gram-positive organisms such as E. coli and Streptococci.


The antibiotic that is given is dependent on the strain of bacteria that is present.


Cephalexin is a semi-synthetic cephalosporin antibiotic and works in the same way as penicillin. It is given for treatment of bacterial infections in the ear, skin and urinary tract.

The drug works by disrupting the capability of the bacterial cells to establish and repair the cell wall. Take note that this is not given for individuals who are highly sensitive to antibiotics.


Augmentin is included in the penicillin group of antibiotics. It is structured to fight the penicillin-resistant bacterial strains. Aside from an infected wound, it is also given to treat cases of pneumonia, sinusitis, bronchitis and ear infections.

The oral combination of Augmentin includes amoxicillin which is a semi-synthetic penicillin and clavulanate potassium which is a potassium salt. Since Augmentin is a beta-lactamase inhibitor, its clavulanate potassium component overcomes granting immunity in beta-lactamase releasing bacteria, thus counteracting any possible bacterial resistance to amoxicillin.
