Treatment of Tonsillitis with Congestion and Plugged Ears: Kenalog IM and Oral Antibiotics

The use of intramuscular corticosteroids like Kenalog (triamcinolone) 40mg is not recommended or supported by evidence-based guidelines for the treatment of acute tonsillitis, even when accompanied by congestion and plugged ears; oral antibiotics alone are appropriate when bacterial infection is confirmed.

Antibiotic Treatment for Tonsillitis

When Antibiotics Are Indicated

  • Antibiotics should only be prescribed for tonsillitis when group A streptococcal (GAS) infection is confirmed or highly probable based on clinical scoring systems (Centor, McIsaac, or FeverPAIN scores) 1
  • Penicillin or amoxicillin remains the first-line antibiotic choice for confirmed GAS pharyngitis/tonsillitis 2, 3
  • Standard dosing is penicillin V 50 mg/kg/day in 4 doses for 10 days (max 2000 mg/day) or amoxicillin 50 mg/kg/day 2

Alternative Antibiotics for Treatment Failure

  • If the patient has received antibiotics in the past 30 days or has failed initial penicillin therapy, consider amoxicillin-clavulanate (40 mg amoxicillin/kg/day) to cover beta-lactamase producing bacteria that may "shield" GAS from penicillin 2, 4
  • Beta-lactamase-producing bacteria are recovered from over 75% of tonsils in patients with recurrent infection and can inactivate penicillin 4
  • For penicillin-allergic patients, clindamycin (20-30 mg/kg/day in 3 doses for 10 days) is recommended 2

Management of Associated Congestion and Plugged Ears

Eustachian Tube Dysfunction vs. Acute Otitis Media

  • Congestion and plugged ears with tonsillitis typically represent eustachian tube dysfunction from upper respiratory inflammation, not necessarily acute otitis media (AOM) 2
  • Acute otitis media requires specific diagnostic criteria: moderate to severe bulging of the tympanic membrane OR new onset otorrhea, OR mild bulging with recent ear pain and intense erythema 2
  • If true AOM is diagnosed alongside tonsillitis, amoxicillin or high-dose amoxicillin-clavulanate (90 mg/kg/day amoxicillin component) provides coverage for both conditions 2

When Additional Antibiotics May Be Needed

  • If bacterial rhinosinusitis is also present (symptoms >10 days or worsening after initial improvement), amoxicillin-clavulanate (1.75-4 g/250 mg per day in adults) covers both tonsillitis and sinus pathogens including Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis 2

Why Kenalog IM Is Not Recommended

Lack of Guideline Support

  • No major infectious disease or otolaryngology guidelines recommend intramuscular corticosteroids for acute tonsillitis or associated upper respiratory symptoms 2, 1
  • The IDSA guideline for streptococcal pharyngitis makes no mention of corticosteroid therapy as part of standard treatment 2
  • The AAP guideline for acute otitis media does not recommend systemic corticosteroids for ear congestion or plugged ears 2

Potential Risks Without Proven Benefits

  • Systemic corticosteroids can mask symptoms without treating the underlying infection, potentially delaying recognition of treatment failure or complications
  • Intramuscular depot corticosteroids provide prolonged immunosuppression (weeks), which could theoretically increase risk of suppurative complications like peritonsillar abscess, though this specific risk is not well-studied in this context
  • There is no evidence that corticosteroids improve the resolution of eustachian tube dysfunction or middle ear effusion associated with upper respiratory infections 2

Recommended Treatment Algorithm

Step 1: Confirm Bacterial Tonsillitis

  • Use clinical scoring (Centor/McIsaac/FeverPAIN) or rapid antigen detection test for GAS 1
  • Only prescribe antibiotics if bacterial infection is confirmed or highly probable 1

Step 2: Select Appropriate Antibiotic

  • First-line: Penicillin V or amoxicillin for 10 days 2, 3
  • If recent antibiotic use (past 30 days) or treatment failure: Amoxicillin-clavulanate 2
  • If penicillin allergy: Clindamycin 2

Step 3: Symptomatic Management

  • Analgesics (acetaminophen or ibuprofen) for pain and fever 2, 5
  • Supportive care for congestion (saline irrigation, decongestants if appropriate)
  • Avoid intramuscular corticosteroids

Step 4: Reassess at 48-72 Hours

  • If no improvement or worsening symptoms, reassess diagnosis and consider antibiotic change 2, 1
  • Persistent middle ear effusion after resolution of acute symptoms is common (60-70% at 2 weeks) and does not require additional antibiotics 2

Common Pitfalls to Avoid

  • Do not use systemic corticosteroids as routine treatment for tonsillitis or associated upper respiratory symptoms - this lacks evidence and may mask complications
  • Do not prescribe antibiotics for viral pharyngitis/tonsillitis, which represents the majority of cases 3, 1
  • Do not confuse eustachian tube dysfunction (plugged ears from congestion) with acute otitis media requiring specific treatment 2
  • Do not continue the same antibiotic beyond 72 hours without clinical improvement - reassess and change therapy 2, 5
