Management of Recurring Herpes Simplex on Cheek of a 6-Year-Old Boy

Oral acyclovir is the recommended treatment for recurring herpes simplex on the cheek of a 6-year-old boy, with a dosage of 20 mg/kg every eight hours for 7-10 days. 1

Initial Management

For a 6-year-old child with recurring herpes simplex virus (HSV) infection on the cheek:

1. Acute Episode Treatment:

   • Oral acyclovir at 20 mg/kg every 8 hours for 7-10 days 1
   • Treatment may be extended if healing is incomplete after 10 days 2
   • Early treatment helps reduce pain, speeds healing, and shortens viral shedding duration

2. Clinical Assessment:

   • Confirm diagnosis based on characteristic grouped vesicles or ulcers on an erythematous base 3
   • Assess severity and frequency of recurrences
   • Evaluate for potential complications (secondary bacterial infection)

Suppressive Therapy Considerations

If recurrences are frequent (≥6 episodes per year) or causing significant distress:

• Consider suppressive therapy with oral acyclovir 4
• For children under 12 years, oral acyclovir at 20 mg/kg every 8 hours 1
• Monitor renal function before starting therapy 4
• Ensure adequate hydration during treatment 4

Patient/Family Education

Essential counseling points:

• Avoid direct contact with lesions to prevent spread to other body sites or individuals
• Maintain good hand hygiene, especially after touching lesions
• Recognize early prodromal symptoms (tingling, burning) to initiate early treatment
• Understand that HSV is a recurrent condition that can be managed but not cured

Follow-up Recommendations

• Assess response to therapy within 72 hours 4
• Continue follow-up until complete resolution of lesions
• Consider referral to pediatric dermatology or infectious disease specialist if:
  • Lesions are severe or extensive
  • Recurrences are very frequent
  • Patient is immunocompromised

Special Considerations

• For immunocompromised children, more aggressive therapy may be required 2
• If oral lesions are severe and affecting oral intake, ensure adequate hydration and pain control
• For very frequent recurrences, long-term suppressive therapy has been shown to be safe and effective in reducing recurrence frequency 5

Treatment Alternatives

While oral acyclovir is the primary treatment, alternatives include:

• Valacyclovir (for older children): Better bioavailability than acyclovir but dosing recommendations not established for young children 1
• Famciclovir: Also has better bioavailability than acyclovir but pediatric dosing not well established 1

Common Pitfalls to Avoid

• Delaying treatment beyond 72 hours of symptom onset significantly reduces efficacy 6
• Using topical acyclovir alone is substantially less effective than systemic therapy 2
• Failing to consider suppressive therapy for children with frequent recurrences
• Overlooking the psychological impact of visible facial lesions in school-aged children

Oral acyclovir has demonstrated safety and efficacy in pediatric patients with HSV infections 7, making it the cornerstone of management for recurring herpes simplex in children.
