What is an antibiotic?
An antibiotic is a powerful medication designed to kill bacteria or stop them from growing, such as an illness caused by strep throat. They cannot cure illnesses caused by viruses, such as a cold or the flu. Different antibiotics may be used for different types of bacterial infections. Your health care provider will determine what infection you have and if an antibiotic is appropriate to treat it.
