From the Guidelines
Yes, it is often appropriate to initiate treatment for genital herpes before laboratory test results are available, especially when clinical presentation strongly suggests herpes infection. This approach is supported by the 2022 review of the evidence for the 2021 Centers for Disease Control and Prevention sexually transmitted infections treatment guidelines, which highlights the importance of early treatment in managing genital herpes 1. The primary goals of treatment are to prevent symptoms and recurrences, improve quality of life, and prevent transmission to sexual partners.
When treating genital herpes empirically, antiviral medications such as acyclovir, valacyclovir, or famciclovir are typically used. For first episodes, the recommended dosages are acyclovir (400mg three times daily for 7-10 days), valacyclovir (1g twice daily for 7-10 days), or famciclovir (250mg three times daily for 7-10 days). For recurrent episodes, the same medications are used but for shorter durations (typically 3-5 days).
Key considerations while awaiting test results include:
- Avoiding sexual contact to prevent transmission
- Keeping the affected area clean and dry
- Wearing loose clothing to minimize discomfort
- Taking over-the-counter pain relievers if needed
Early initiation of antiviral treatment, ideally within 72 hours of symptom onset, is crucial as it can reduce the severity and duration of the outbreak, relieve pain, and potentially decrease viral shedding 1. Delaying treatment until test confirmation could result in missing the optimal window for antiviral effectiveness, particularly for patients experiencing significant pain or extensive lesions.

From the Research
Treatment of Genital Herpes
- The treatment of genital herpes typically involves antiviral medications such as acyclovir, valacyclovir, and famciclovir 2.
- These medications can be used to treat the initial outbreak, as well as to suppress future outbreaks and prevent transmission to others 3.
Initiating Treatment Before Test Results
- There is evidence to suggest that initiating treatment for genital herpes before laboratory test results are back may be beneficial in reducing the duration and severity of symptoms 4, 5.
- A study found that oral acyclovir reduced the duration of symptoms in individuals undergoing their first episode of genital herpes, and that early treatment may abort the episode in some patients 4, 5.
- However, it is essential to note that the diagnosis of genital herpes should be confirmed through laboratory tests, such as type-specific polymerase chain reaction or viral culture of active lesions, to ensure accurate treatment 6.
Considerations for Treatment
- The choice of treatment for genital herpes depends on various factors, including the severity of symptoms, the frequency of outbreaks, and the patient's overall health 2, 3.
- Suppressive antiviral therapy may be recommended for patients with frequent recurrences, and antiviral suppression is recommended during pregnancy to prevent transmission to the newborn 5, 6.
- It is crucial to follow the recommended treatment guidelines and consult with a healthcare professional to determine the best course of treatment for individual cases of genital herpes 2, 3, 4, 5, 6.
