From the Guidelines

The treatment of Herpes Labialis typically involves the use of antiviral medications, such as acyclovir (200-400mg, 3-5 times daily for 7-10 days) or valacyclovir (500-1000mg, twice daily for 7-10 days), to reduce the severity and duration of symptoms 1.

Treatment Options

  • Topical applications, including docosanol 10% cream (applied 5 times daily for 4 days) or penciclovir 1% cream (applied every 2 hours during waking hours for 4 days), may also be used to alleviate symptoms 1.
  • In severe cases, oral famciclovir (1500mg, single dose or 500mg, twice daily for 7-10 days) may be prescribed to manage symptoms and prevent recurrence 1.

Key Considerations

  • The aim of antiviral therapy is to block viral replication to enable shortening the duration of symptoms and accelerate the resolution of lesions 1.
  • Early treatment is crucial to ensure an optimal therapeutic beneficial effect 1.
  • Patient education using targeted campaigns is specifically recommended for HSV, stressing the importance of initiating treatment during the prodrome phase 1.

From the FDA Drug Label

Herpes labialis (cold sores):The recommended dosage of famciclovir tablets for the treatment of recurrent herpes labialis is 1500 mg as a single dose. Therapy should be initiated at the first sign or symptom of herpes labialis (e.g., tingling, itching, burning, pain, or lesion).

Denavir was studied in two double-blind, placebo (vehicle)-controlled trials for the treatment of recurrent herpes labialis in which otherwise healthy adults were randomized to either Denavir or placebo. Therapy was to be initiated by the subjects within 1 hour of noticing signs or symptoms and continued for 4 days, with application of study medication every 2 hours while awake.

The treatment for Herpes Labialis is:

  • Famciclovir (PO): 1500 mg as a single dose, initiated at the first sign or symptom of herpes labialis 2
  • Penciclovir (TOP): applied every 2 hours while awake for 4 days, initiated within 1 hour of noticing signs or symptoms 3
