II. Management: General Measures

  1. Symptomatic relief
    1. Warm, moist compresses over sinuses
    2. Tylenol
  2. Nasal Saline spray (2% buffered saline) or Neti Pot
    1. Effective Decongestant
    2. Also use as pretreatment prior to Intranasal Steroid
    3. Effective in recurrent Sinusitis when used daily
      1. Rabago (2002) J Fam Pract 51:1049-55 [PubMed]
      2. Papsin (2003) Can Fam Physician 49:168-73 [PubMed]
  3. Mucolytic
    1. Guaifenesin (e.g. Mucinex) 600 to 1200 mg PO bid
  4. Combination Mucolytic with Decongestant
    1. Entex PSE bid
  5. Topical Decongestants (Maximum of 3 days of use)
    1. Oxymetazoline (Afrin)
      1. Avoid afrin (Oxymetazoline) in children (due to central alpha-2 agonist, Clonidine-like CNS depression)
      2. If a nasal Decongestant is used in children, Neo-Synephrine (Phenylephrine) is preferred
    2. Phenylephrine (Neo-Synephrine)
  6. Systemic Decongestants (e.g Pseudoephedrine)
    1. Not recommended due to systemic adverse effects and adds little to symptomatic relief over other options
    2. Diversion to Methamphetamine production only reinforces a policy to discourage pseudophedrine availability and use
    3. Consider 3 days of Afrin nasal spray for facial pain relief
  7. Intranasal Steroids (treat for 3-6 weeks minimum if indicated)
    1. Chronic Sinusitis
    2. Nasal Polyps
    3. Dolor (2001) JAMA 286:3097-105 [PubMed]
  8. Avoid Antihistamines
    1. Dry secretions
    2. Impede osteomeatal complex drainage

III. Management: Antibiotics

  1. Indicated only in acute Bacterial Sinusitis
    1. See Acute Sinusitis for Diagnosis
    2. See Sinusitis Prediction Rules
    3. Only 10% of Sinusitis cases are Bacterial
    4. Persistent Sinusitis symptoms >10 days
    5. Moderate to severe facial pain for at least 3-4 days
    6. Fever over 101 to 102 F
    7. Upper respiratory symptoms for 5 to 6 days that resolved and then recurred (double-Hump Sign)
  2. Protocol
    1. Antibiotic course
      1. Minimum course: 10 days (5-7 days may be sufficient)
        1. Falagas (2009) Br J Clin Pharmacol 67(2): 161-71 [PubMed]
      2. Consider longer course for persistent or recurrent symptoms suggestive of Bacterial Sinusitis: 14 days
    2. Change antibiotic if no improvement in 7 days
      1. Beta-lactamase resistance in acute cases: <30%
      2. Beta-lactamase resistance in chronic cases: 40-50%
  3. First-Line
    1. Indications to start on first-line agents
      1. Mild to moderate symptoms
      2. No Antibiotic Resistance risk factors
        1. No daycare exposure
        2. No recent antibiotic use in last 1-3 months
        3. Immunosuppression
        4. High local Antibiotic Resistance rates
      3. Consider starting with high dose Amoxicillin or second-line antibiotics if higher risk for Antibiotic Resistance
        1. Guidelines as of 2015, recommend Amoxicillin-clavulanate as a first-line agent
    2. Amoxicillin
      1. Adult: 1000 mg orally twice daily
        1. Consider Augmentin instead as first-line management in adults
      2. Child: 90 mg/kg/day divided bid to tid (high dose)
      3. Disadvantages: Misses Beta-lactamase producers
        1. HaemophilusInfluenzae
        2. Moraxella catarrhalis
        3. Penicillin Resistant Pneumococcus (increasing)
  4. Second-Line
    1. Indications to start on second-line agents
      1. Severe symptoms
      2. Consider for daycare exposure or recent antibiotic use (or use high dose Amoxicillin instead)
    2. Amoxicillin-Clavulanate (Augmentin)
      1. Adult: 875 mg PO bid or 500 mg PO tid
      2. Child
        1. TID: 40 mg/kg/day divided q8 hours
        2. BID: 45 mg/kg/day divided q12 hours
    3. Cefuroxime (Zinacef, Ceftin)
      1. Adult: 250 to 500 mg PO bid
      2. Child: 30 mg/kg/day divided bid
    4. Cefpodoxime (Vantin)
      1. Adult: 200 mg PO bid
      2. Child: 10 mg/kg/day once daily
    5. Cefdinir (Omnicef)
      1. Adult: 300 mg PO bid or 600 mg PO qd
      2. Child: 14 mg/kg/day divided qd-bid
    6. Avoid Cefixime
      1. Poor Gram Positive Bacteria coverage
  5. Third Line
    1. Consider adding Flagyl to second-line agents
    2. Consider second-line agent for longer course (4 week)
    3. Fluoroquinolones (avoid under age 16 years)
      1. Levofloxacin (Levaquin) 500 mg daily
      2. Moxifloxacin (Avelox) 400 mg daily

IV. Management: Penicillin or Cephalosporin Allergy

  1. Clindamycin (children with Penicillin Allergy)
    1. Dosing: 30-40 mg/kg/day divided three to four times daily
    2. Consider in combination with Rifampin if severe
    3. Poor efficacy against Gram Negative Bacteria
    4. Increasing resistance in Haemophilus and Moraxella
  2. Doxycycline (avoid under age 8 years old)
    1. Dosing: 100 mg orally twice daily for 5-7 days
  3. Fluoroquinolones (avoid under age 16 years old)
    1. See Third line agents above
  4. Agents that are no longer recommended due to high resistance rates
    1. Macrolide antibiotics (Erythromycin, Azithromycin, Clarithromycin)
    2. Trimethoprim-Sulfamethoxazole (Bactrim, Septra)

V. Management: Referral Indications to ENT

  1. See Also Sinus Surgery
  2. Sinusitis refractory to maximal medical management
    1. Recurrent Acute Sinusitis
    2. Persistent Chronic Sinusitis Symptoms
  3. Complicated Sinusitis
    1. Immunocompromised patient
    2. Toxic appearance
    3. Suspected contiguous orbital or cerebral involvement
      1. See red flag symptoms in Acute Sinusitis
      2. Sphenoid and Frontal Sinusitis are higher risk
