What is the treatment for a viral ulcer on the tongue?

Treatment of Viral Ulcer on the Tongue

Topical antiviral medications and oral antiviral therapy are the primary treatments for viral ulcers on the tongue, with treatment initiated as early as possible to ensure optimal therapeutic effect. 1

Diagnosis First

Before initiating treatment, proper identification of the viral etiology is essential:

• Most viral ulcers on the tongue are caused by herpes simplex virus (HSV-1 or HSV-2)
• Clinical presentation typically includes:
  • Prodromal symptoms: itching, burning, or paresthesia
  • Progression through stages: erythema, papule, vesicle, pustulation, ulceration, and scabbing 1
• For atypical presentations or persistent ulcers (>2 weeks), consider:
  • Blood tests to rule out systemic conditions
  • Biopsy for definitive diagnosis 2

Treatment Algorithm

First-Line Treatment

1. Topical antiviral medications:

   • Apply multiple times daily for up to 5 days
   • Most effective when started within the first 24 hours of symptoms 1

2. Oral antiviral therapy (preferred for more severe cases):

   • Options include:
     • Acyclovir (800 mg 2-5 times daily)
     • Valacyclovir (500-1000 mg twice daily)
     • Famciclovir (125-500 mg twice daily)
   • Start within 72 hours of symptom onset for maximum effectiveness 2
   • Continue for 5-10 days depending on severity

For Immunocompromised Patients

Immunocompromised patients require more aggressive treatment due to risk of prolonged and severe episodes:

• High-dose intravenous acyclovir (20 mg/kg body weight/dose three times daily) for severe cases 1
• Longer duration of therapy may be necessary
• Monitor for potential dissemination of infection

Supportive Care

• Pain management:
  • Topical anesthetics for temporary relief
  • Oral analgesics for more severe pain 2
• Maintain hydration and nutrition
• Regular oral hygiene with soft toothbrush and mild fluoride toothpaste 2

Special Considerations

Recurrent Episodes

For patients with frequent recurrences:

• Consider prophylactic antiviral therapy
• Apply sunscreen or zinc oxide to decrease probability of recurrent outbreaks 1

Treatment Resistance

In cases of acyclovir-resistant viral ulcers:

• Foscarnet is the treatment of choice 3
• Consider consultation with infectious disease specialist

Differential Diagnosis

Be aware that not all oral ulcers are viral in origin:

• Aphthous ulcers ("canker sores") are non-viral and typically respond to topical steroids
• Bacterial infections may require antibiotics
• Fungal infections may need antifungal therapy 1

Monitoring and Follow-up

• Regular assessment of pain, at least once daily
• Monitor for healing progression
• Follow-up every 3-6 months for persistent symptomatic cases 2
• Consider referral to specialist if:
  • Ulcers persist beyond 2 weeks despite treatment
  • Systemic symptoms develop
  • Patient is severely immunocompromised

Prevention

• Avoid known triggers (stress, UV exposure, trauma)
• Maintain good oral hygiene
• Replace toothbrush monthly to prevent bacterial accumulation 2

Remember that early treatment is crucial, as peak viral titers occur in the first 24 hours after lesion onset, with subsequent progressive decline as lesions convert to ulcers/crust 1.
