You feel miserable. Work is piling up. You want to feel better. Your health care provider wants you to feel better. If you're confused, you're not alone.
Antibiotics are strong medicines that can stop some infections and save lives.

As many as half of outpatient antibiotic prescriptions written every year are unnecessary, according to the Centers for Disease Control and Prevention.
