What is the recommended treatment for ulcerated tonsillitis?

Treatment for Ulcerated Tonsillitis

For ulcerated tonsillitis, penicillin V or amoxicillin for 10 days is the recommended first-line treatment when bacterial etiology is confirmed, particularly for Group A Streptococcal infection.

Diagnosis and Etiology

Before initiating treatment, it's crucial to determine the cause of ulcerated tonsillitis:

• 70-95% of tonsillitis cases are viral in origin 1
• 5-15% of cases in adults and 15-30% in children aged 5-15 years are caused by Group A beta-hemolytic streptococcus (GABHS) 1

Diagnostic Approach:

• Use Centor criteria to assess likelihood of bacterial infection 2:

  • Fever by history
  • Tonsillar exudates
  • Tender anterior cervical adenopathy
  • Absence of cough

• Clinical features suggesting viral etiology (not requiring antibiotics) 2:

  • Cough
  • Rhinorrhea (runny nose)
  • Hoarseness
  • Oral ulcers

Treatment Algorithm

1. Confirmed or Highly Suspected Bacterial Tonsillitis:

First-line treatment:

• Penicillin V: 250 mg 2-3 times daily (children), 500 mg 2-3 times daily (adolescents/adults) for 10 days 2
• OR Amoxicillin: 50 mg/kg once daily (maximum 1000 mg) or 25 mg/kg twice daily (maximum 500 mg per dose) for 10 days 2, 3

For penicillin-allergic patients:

• Clindamycin: 7 mg/kg three times daily (maximum 300 mg per dose) for 10 days 2
• OR Azithromycin: 12 mg/kg once daily (maximum 500 mg) for 5 days 2, 3

Important note: A full 10-day course of antibiotics is critical when treating confirmed streptococcal tonsillitis to prevent complications such as rheumatic fever 2

2. Viral Tonsillitis:

• Supportive care with analgesia and hydration 4
• NSAIDs (ibuprofen) are first-line for symptom management 2
• Acetaminophen for pain and fever relief 2
• Warm salt water gargles and throat lozenges 2

Special Considerations

Recurrent Tonsillitis:

• For patients with recurrent episodes, clindamycin or amoxicillin with clavulanate may be superior to penicillin in preventing future attacks 5
• Consider tonsillectomy based on Paradise criteria (≥7 well-documented episodes in the preceding year, OR ≥5 episodes in each of the preceding 2 years, OR ≥3 episodes in each of the preceding 3 years) 2

Immunocompromised Patients:

• Be vigilant for atypical presentations such as herpes simplex virus-induced necrotizing tonsillitis 6
• Early recognition is essential when there's no improvement with initial antibiotic therapy within 24-72 hours 6
• Consider antiviral agents if antibiotic treatment fails in immunocompromised patients 6

Follow-up and Monitoring

• Patients are considered non-contagious after 24 hours of appropriate antibiotic therapy 2
• Advise patients to return for evaluation if symptoms worsen, persist beyond 7 days, or if severe symptoms develop 2
• Failure to complete the full 10-day course of antibiotics may lead to treatment failure and increased risk of complications 2

Common Pitfalls to Avoid

1. Empiric antibiotic treatment without testing - contributes to antibiotic resistance and unnecessary side effects 2
2. Inadequate duration of antibiotic therapy - a full 10-day course is necessary to prevent complications 2
3. Failure to recognize viral etiology - most cases are viral and don't require antibiotics 1, 4
4. Missing atypical presentations in immunocompromised patients - consider HSV or other unusual pathogens if standard treatment fails 6
