Treatment for Acute Sinus Infection

Initial Antibiotic Therapy

The American Academy of Allergy, Asthma, and Immunology recommends amoxicillin-clavulanate as the first-line treatment for acute sinus infection, with alternatives including second/third generation cephalosporins or pristinamycin for those with penicillin allergies 1, 2
Standard dosing of amoxicillin-clavulanate is typically for 7-10 days, though some cephalosporins have shown effectiveness in 5-day courses 1
For patients with penicillin allergy, alternatives include second/third generation cephalosporins, such as cefuroxime-axetil or cefpodoxime-proxetil 2, 1

Nasal corticosteroids may be helpful in patients with acute sinusitis, particularly when there is marked mucosal edema 2, 3
Short-term oral corticosteroids can be considered as an adjunct when the patient fails to respond to initial treatment 3

Patients should show improvement within 3-5 days of starting antibiotics, and if symptoms worsen or don't improve, reevaluation is necessary 2

For poor response to initial therapy, switch to an antibiotic that covers resistant bacteria, such as high-dose amoxicillin-clavulanate or fluoroquinolones 2, 4, 1

Patients with recurrent sinusitis should be evaluated for underlying inflammation and allergies, immunodeficiency, anatomic abnormalities, and considered for referral to an allergist-immunologist or otolaryngologist 2

Watch for signs of complications requiring immediate attention, such as facial swelling or visual changes, and ensure patients complete the full course of antibiotics to prevent relapse 3
