From the Guidelines
Sinusitis should be treated with antibiotics such as amoxicillin (500mg three times daily for 5-10 days) or amoxicillin-clavulanate if symptoms persist beyond 10 days or are severe, as recommended by the most recent guidelines 1. The treatment of sinusitis depends on the cause and severity of the condition. For acute viral sinusitis, treatment focuses on symptom relief with over-the-counter pain relievers like acetaminophen or ibuprofen (400-600mg every 6-8 hours), saline nasal sprays, and nasal decongestants like pseudoephedrine (30-60mg every 4-6 hours, not exceeding 240mg daily) 1. Some key points to consider in the treatment of sinusitis include:
- The use of antibiotics such as amoxicillin or amoxicillin-clavulanate for bacterial sinusitis, with a treatment duration of 5-10 days 1
- The use of nasal steroid sprays like fluticasone (1-2 sprays per nostril daily) to reduce inflammation 1
- The importance of seeking immediate medical attention if symptoms worsen or include high fever, severe headache, confusion, stiff neck, or visual changes 1
- The potential need for specialized treatment from an ear, nose, and throat specialist for chronic sinusitis lasting more than 12 weeks 1 It is also important to note that the role of antibiotics in chronic sinusitis is controversial, and the use of antibiotics should be based on the specific cause and severity of the condition 1. Additionally, home remedies such as applying warm compresses to the face, staying hydrated, using a humidifier, and rinsing sinuses with a neti pot using distilled water can help alleviate symptoms 1. Overall, the treatment of sinusitis should be individualized based on the specific cause and severity of the condition, and should prioritize reducing inflammation, fighting infection, promoting drainage, and relieving pressure in the sinuses 1.
From the FDA Drug Label

- For pediatric patients, the recommended dose is 10 mg/kg once daily for 3 days. 2
From the Research
Treatment Options for Sinusitis
- Azithromycin and amoxicillin/clavulanate are two commonly used antibiotics for treating acute sinusitis 3, 4, 5
- A 3-day course of azithromycin was found to be as effective as a 10-day course of amoxicillin/clavulanic acid in adults with acute sinusitis 3
- Short-course antibiotic therapy (less than or equal to 5 days) may have equivalent or superior efficacy compared to traditional longer therapies (10-14 days) 6
- Azithromycin extended release was found to have a faster symptom resolution compared to amoxicillin/clavulanate in patients with acute sinusitis 4
Comparison of Antibiotics
- Clarithromycin extended-release was found to be comparable to amoxicillin/clavulanate in patients with acute bacterial sinusitis, with some measures showing superiority 5
- Amoxicillin/clavulanate with or without intranasal fluticasone was found to be effective in treating uncomplicated acute rhinosinusitis in children, with the addition of intranasal fluticasone showing higher efficacy in patients with allergic rhinitis 7
Duration of Treatment
- The traditional 10- to 14-day treatment course for acute sinusitis is not derived from a strong scientific or medical rationale, and shorter courses of antibiotic therapy may be effective 6
- A 5-day course of antibiotic therapy may be sufficient for uncomplicated acute maxillary sinusitis in adults, but further research is needed for other types of sinusitis and in children 6
