Treatment of Uncomplicated Acute Bacterial Rhinosinusitis with Non-Type 1 Penicillin Hypersensitivity
This protocol addresses uncomplicated acute bacterial rhinosinusitis (ABRS) in patients with a documented non-type 1 hypersensitivity to penicillin — a clinically important subgroup requiring a targeted antibiotic selection approach.
Clinical Scenario
ABRS is diagnosed when symptoms — purulent nasal drainage with nasal obstruction, facial pain or pressure-fullness, or both — persist without improvement for at least 10 days from symptom onset, or worsen within 10 days after an initial improvement (double worsening). This protocol applies specifically to patients presenting with this picture who also carry non-type 1 penicillin hypersensitivity.
Treatment Approach
For patients with non-type 1 penicillin hypersensitivity, specific oral antibiotic alternatives — including agents from the tetracycline class and third-generation oral cephalosporins — are recommended. Combination use with an additional antibiotic is addressed within the protocol.
The complete selection, combination options, and course details are available in the full protocol below.
Clinical Goal
Signs and symptoms of presumed ABRS should generally improve within 3 to 5 days after initiating antibiotic therapy.

- A clinician should diagnose ABRS when (a) symptoms or signs of acute rhinosinusitis (purulent nasal drainage accompanied by nasal obstruction, facial pain-pressure-fullness, or both) persist without evidence of improvement for at least 10 days beyond the onset of upper respiratory symptoms, or (b) symptoms or signs of acute rhinosinusitis worsen within 10 days after an initial improvement (double worsening).
- For patients with non-type 1 penicillin hypersensitivity, either doxycycline or a third-generation oral cephalosporin (cefixime 400 mg PO od or cefpodoxime 200 mg PO bid) with or without clindamycin (450 mg PO tid) is recommended.
- The purpose of this statement is to emphasize that signs and symptoms of presumed ABRS should generally improve within 3 to 5 days after initiating antibiotic therapy.
