Management of Recently Diagnosed Oral and Genital Herpes
For patients recently diagnosed with oral and genital herpes, antiviral therapy with acyclovir, valacyclovir, or famciclovir is recommended, along with comprehensive counseling on disease management, transmission prevention, and treatment options for both initial episodes and recurrent outbreaks. 1
Initial Treatment for First Clinical Episode
Recommended Antiviral Regimens:
For genital herpes:
- Acyclovir 400 mg orally three times a day for 7-10 days, OR
- Acyclovir 200 mg orally five times a day for 7-10 days, OR
- Famciclovir 250 mg orally three times a day for 7-10 days, OR
- Valacyclovir 1 g orally twice a day for 7-10 days 1
For oral herpes (cold sores):
- Higher dosages of acyclovir (400 mg orally five times a day) may be used
- Valacyclovir and famciclovir are likely effective but have less clinical experience documented for oral infections 1
Note: Treatment may need to be extended if healing is incomplete after 10 days of therapy.
Patient Counseling
Counseling is a critical component of management and should include:
- Natural history education: Explain the chronic nature of herpes, potential for recurrent episodes, asymptomatic viral shedding, and sexual transmission
- Transmission prevention:
- Pregnancy implications: Explain neonatal infection risk to all patients, including men. Women of childbearing age should inform healthcare providers about their HSV infection during pregnancy 1
- Treatment options: Advise patients that episodic therapy can shorten recurrent episodes and suppressive therapy can prevent outbreaks 1
Management of Recurrent Episodes
Two approaches are available for managing recurrent episodes:
1. Episodic Therapy
Recommended when treatment is started during prodrome or within 1 day of lesion onset:
- Acyclovir 400 mg orally three times a day for 5 days, OR
- Acyclovir 200 mg orally five times a day for 5 days, OR
- Acyclovir 800 mg orally twice a day for 5 days, OR
- Famciclovir 125 mg orally twice a day for 5 days, OR
- Valacyclovir 500 mg orally twice a day for 5 days 1
Patients should be provided with a prescription so treatment can be initiated at the first sign of prodrome or lesions.
2. Suppressive Therapy
Recommended for patients with frequent recurrences (≥6 per year):
- Acyclovir 400 mg orally twice a day, OR
- Famciclovir 250 mg orally twice a day, OR
- Valacyclovir 250 mg orally twice a day, OR
- Valacyclovir 500 mg orally once a day, OR
- Valacyclovir 1,000 mg orally once a day 1
Important note: Valacyclovir 500 mg once daily may be less effective for patients with very frequent recurrences (≥10 episodes per year).
Special Considerations
Severe Disease
For patients with severe disease requiring hospitalization:
- Acyclovir 5-10 mg/kg body weight IV every 8 hours for 5-7 days or until clinical resolution 1
Treatment Duration
- Daily suppressive therapy has been documented as safe for up to 6 years with acyclovir and 1 year with valacyclovir and famciclovir 1
- After 1 year of continuous suppressive therapy, consider discontinuation to assess recurrence frequency, as recurrences often decrease over time 1
Common Pitfalls to Avoid
- Delayed treatment initiation: Efficacy is highest when treatment begins during prodrome or within 24 hours of lesion appearance
- Inadequate counseling: Failure to address psychological aspects and transmission prevention
- Not providing episodic therapy prescriptions: Patients should have medication on hand to start at first signs of recurrence
- Overlooking pregnancy implications: All women of childbearing age should be counseled about neonatal herpes risk
- Using topical acyclovir: Topical therapy is substantially less effective than systemic medication 1
Remember that while antiviral medications can control symptoms and reduce transmission risk, they do not cure herpes infection or completely eliminate the risk of transmission to others 2.
