Acute bacterial rhinosinusitis in adults: part II. Treatment.
Although most cases of acute rhinosinusitis are caused by viruses, acute bacterial rhinosinusitis is a fairly common complication. Even though most patients with acute rhinosinusitis recover promptly without it, antibiotic therapy should be considered in patients with prolonged or more severe symptoms. To avoid the emergence and spread of antibiotic-resistant bacteria, narrow-spectrum antibiotics such as amoxicillin should be used for 10 to 14 days. In patients with mild disease who have beta-lactam allergy, trimethoprim/sulfamethoxazole or doxycycline are options. Second-line antibiotics should be considered if the patient has moderate disease, recent antibiotic use (past six weeks), or no response to treatment within 72 hours. Amoxicillin-clavulanate potassium and fluoroquinolones have the best coverage for Haemophilus influenzae and Streptococcus pneumoniae. In patients with beta-lactam hypersensitivity who have moderate disease, a fluoroquinolone should be prescribed. The evidence supporting the use of ancillary treatments is limited. Decongestants often are recommended, and there is some evidence to support their use, although topical decongestants should not be used for more than three days to avoid rebound congestion. Topical ipratropium and the sedating antihistamines have anticholinergic effects that maybe beneficial, but there are no clinical studies supporting this possibility. Nasal irrigation with hypertonic and normal saline has been beneficial in chronic sinusitis and has no serious adverse effects. Nasal corticosteroids also may be beneficial in treating chronic sinusitis. Mist, zinc salt lozenges, echinacea extract, and vitamin C have no proven benefit in the treatment of acute bacterial rhinosinusitis.
