Respiratory Fluoroquinolone Use and Influenza

Respiratory Fluoroquinolone Use and Influenza

The Question

Are the seasonal fluoroquinolone usagepatterns related to the timing of the influenza seasons and what proportion ofuse is associated with influenza activity?

What we found

A contemporaneous relationship betweenseasonal influenza activity and antibiotic use was determined. Specifically, respiratoryfluoroquinolone increases during the same month that influenza activityincreases.

Why it matters

Fluoroquinolone cannot treat viral infections. A significant proportion of the increase ofantimicrobial usage during influenza season is probably unnecessary and probablycontributes to antimicrobial resistance.
