The Centers for Disease Control and Prevention is asking doctors to abide by three principles for antibiotics:
Determine the likelihood of an infection: Antibiotics should never be used for viral infections.
Always weigh benefits versus harms of antibiotics: Symptom reduction and prevention and complications should be weighed against the risk for side effects and drug resistance.
Implement accurate prescribing strategies: Select an appropriate antibiotic and an appropriate dose for the shortest duration required.
