Treatment for Positive HSV-1 and HSV-2 IgG Test Results

Introduction to Treatment Approaches

The Centers for Disease Control and Prevention recommends treatment for symptomatic patients with positive HSV-1 and HSV-2 IgG test results, using oral valacyclovir, acyclovir, or famciclovir 1, 2

For symptomatic patients with active lesions, the American College of Obstetricians and Gynecologists recommends valacyclovir 1 g orally twice daily for 7-10 days, with a strength of evidence rated as high 3
The Centers for Disease Control and Prevention recommends acyclovir 400 mg orally three times daily for 7-10 days for symptomatic patients with active lesions, with a strength of evidence rated as moderate 4, 3
For recurrent episodes, the American College of Obstetricians and Gynecologists recommends valacyclovir 500 mg orally twice daily for 5 days, with a strength of evidence rated as high 2, 3
The Centers for Disease Control and Prevention recommends suppressive therapy with valacyclovir 1 g orally once daily or 500 mg orally once daily for patients with frequent recurrences, with a strength of evidence rated as moderate 2, 3

For HIV-infected patients, the Centers for Disease Control and Prevention recommends higher doses of antivirals, such as acyclovir 400 mg orally 3-5 times daily until clinical resolution, with a strength of evidence rated as low 7, 8
For pregnant women, the American College of Obstetricians and Gynecologists recommends that the safety of systemic acyclovir therapy during pregnancy has not been fully established, with a strength of evidence rated as low 9

The Centers for Disease Control and Prevention recommends advising patients to abstain from sexual activity while lesions are present, with a strength of evidence rated as high 7, 2
The American College of Obstetricians and Gynecologists recommends informing patients about the chronic nature of HSV infection and potential for recurrent episodes, with a strength of evidence rated as moderate 7, 2

The Centers for Disease Control and Prevention recommends that topical acyclovir is substantially less effective than oral therapy and is not recommended, with a strength of evidence rated as high 2, 3
The American College of Obstetricians and Gynecologists recommends that systemic antiviral drugs control symptoms but do not eradicate latent virus or prevent all recurrences, with a strength of evidence rated as moderate 3

The Centers for Disease Control and Prevention recommends avoiding treatment based solely on positive serology without clinical symptoms, with a strength of evidence rated as high 1, 10
The American College of Obstetricians and Gynecologists recommends avoiding delaying treatment beyond 72 hours of symptom onset, which significantly reduces effectiveness, with a strength of evidence rated as moderate 2
