Antiviral Treatment for HSV-1 Infections

First-Line Treatment Options

The American College of Physicians recommends valacyclovir 1g orally twice daily for 7-10 days as the first-line treatment for HSV-1 infections 1
Acyclovir 400mg orally three times daily for 7-10 days is an effective alternative option 1
Famciclovir 250mg orally three times daily for 7-10 days is another recommended alternative 1

For first clinical episodes, valacyclovir 1g orally twice daily for 7-10 days is recommended 1
Alternative regimen: acyclovir 200mg orally 5 times a day for 7-10 days or until clinical resolution 2, 3
For recurrent episodes, valacyclovir 500mg orally twice daily for 5 days is recommended 4

For immunocompromised patients, higher dosages may be beneficial, such as acyclovir 400mg orally 3-5 times daily until clinical resolution 1
The Centers for Disease Control and Prevention recommends monitoring for development of resistance, especially in severely immunocompromised patients 1

Early initiation of therapy is crucial for optimal effectiveness (within 72 hours of symptom onset) 1, 4
Antiviral medications neither eradicate latent virus nor affect the risk, frequency, or severity of recurrences after discontinuation 1, 2, 3, 4
The Centers for Disease Control and Prevention recommends that patients should be counseled about the natural history of HSV infection, potential for recurrent episodes, and asymptomatic viral shedding 4
