 Sweetie, want some fruit? You have to use the right tool for the job. A power drill is the wrong tool to slice fruit. Just like an antibiotic is the wrong tool to treat viruses, including colds and flu. Antibiotics are only needed for certain bacterial infections. When they aren't needed, antibiotics won't help you. And the side effects could still hurt you. Ask your health care professional when an antibiotic is the right tool and when it's not. Visit cdc.gov slash antibiotic dash use.
