Frequently Asked Questions
When do I need antibiotics for a sinus infection?
Antibiotics are typically needed if symptoms are severe, last more than 10 days, or initially improve then worsen (double sickening). Our doctors will determine if antibiotics are appropriate for your situation.
How long does a sinus infection last?
Acute sinusitis typically lasts 2-4 weeks. With appropriate treatment, you should feel improvement within a few days. Chronic sinusitis lasts 12 weeks or longer and may need different management.
Can I treat a sinus infection without antibiotics?
Many sinus infections are viral and improve with supportive care including nasal irrigation, steam, and OTC medications. Our doctors can recommend the best approach for your symptoms.
