5-7 days of amoxcillin clavulanate for acute bacterial sinusitis in non pencillin allergic pts
Doxycycline and respiratory quinolones (levofloxacin and moxifloxacin) are alternatives for penicillin allergic pts.
Amoxicillin is not first choice due to resistance with Strep and H influenzae. Macrolides (azithromycin, clarithomycin, bactrim and 2nd and 3rd generation are not recommended as 1st line due to increasing resistance.

overuse from OTC nasal decongestants sprays.
- Spray’s vasoconstrictive effect requires increasing amounts drug for symptomatic relief due to tachyphylaxis and leads to rebound vasodilation and swelling with rhinorrhea.
PTs use more nasal decongestant spray to relieve their symptoms and begins a cycle of congestion with temporary relief.
Pts can also get a emotional lift and become dependent on spray
Diagnosis of rhinitis medicamentosa
history and physical exam with seeing swollen red nasal mucosa.
Treatment involves: medication cessation which can be difficult since pts experience worsening rebound symptoms. Some data shows that intranasal fluticasone for a few days may help alleviate the withdrawal nasal congestion. Some require steroids for severe withdrawal.
Can be prevented via using nasal decongestants for <5 days.
