How long is antibiotic treatment?
For acute, uncomplicated sinus infections treatment is usually 7 to 14 days. A generic or first choice antibiotic will be selected by your physician. If the sinus infection does not resolve after the first course of antibiotics, a second stronger antibiotic will be prescribed. If the sinus infection has been present for several weeks, treatment is extended. Patients with chronic sinusitis and an acute exacerbation will be treated for at least 3 weeks and can be up to 12 weeks.
