Effectiveness of Non-Antibiotic Treatments for Sinus Infections
Research shows that most cases of acute sinus infections (acute rhinosinusitis) resolve without antibiotics. In adults, about 46% recover within one week and 64% within two weeks without antibiotic treatment. Antibiotics provide only a small additional benefit, with 5 to 11 more people out of 100 recovering faster if they take antibiotics, but this comes with a higher risk of side effects such as diarrhea and other adverse reactions. Because of the low risk of serious complications and concerns about antibiotic resistance, antibiotics are not recommended for uncomplicated cases in otherwise healthy adults 1310.
Symptom Relief and Supportive Care for Sinus Infections
For symptom management, several non-antibiotic options are recommended:
- Analgesics (pain relievers) can help reduce facial pain and discomfort.
- Saline nasal irrigation is considered safe, acceptable, and feasible for adults with acute sinusitis. Patients report it as a positive alternative to antibiotics, and it can be used alongside a "watchful waiting" approach 23.
- Topical intranasal glucocorticoids or decongestants may also provide symptom relief .
Watchful Waiting and When to Seek Further Care
"Watchful waiting" is a valid initial approach for most adults with acute sinusitis, as long as they can return for follow-up if symptoms do not improve or worsen. Antibiotics should be reserved for cases where symptoms persist beyond 10 days without improvement, worsen after initial improvement, or if the patient develops severe symptoms 13.
Sinus Infection Treatment in Children
In children, antibiotics can reduce the risk of treatment failure, but most children recover without them. Studies show that 59% of children given a placebo did not experience treatment failure, and the absolute benefit of antibiotics is modest. The risk of side effects, such as diarrhea, is higher with antibiotics. Close observation without immediate antibiotics is a reasonable option for many children, especially those without evidence of bacterial infection 459.
Chronic Sinusitis and Non-Antibiotic Approaches
For chronic sinusitis, there is little evidence that antibiotics are effective. Some studies show a modest improvement in quality of life with long-term antibiotics, but the benefit is small and only seen at the end of treatment. Supportive care and other medical management options are preferred, and more research is needed on long-term outcomes .
Conclusion
Most sinus infections, especially uncomplicated cases in healthy adults and children, resolve without antibiotics. Supportive care—such as pain relievers, saline nasal irrigation, and intranasal steroids—can help manage symptoms. Watchful waiting is a safe and effective approach for many patients, reducing unnecessary antibiotic use and the risk of side effects. Antibiotics should be reserved for severe, persistent, or worsening cases, or when bacterial infection is strongly suspected.
