From the Guidelines
Oral herpes can be effectively treated with antiviral medications like valacyclovir (1g twice daily for 7-10 days), acyclovir (400mg three times daily for 5-10 days), or famciclovir (250mg three times daily for 7-10 days) during active outbreaks, as recommended by the most recent guidelines 1. When considering treatment options, it's essential to prioritize the most recent and highest quality study, which in this case is from 2021 1. The treatment goals are to reduce symptoms, shorten the duration of the outbreak, and improve quality of life. Some key points to consider when treating oral herpes include:
- Antiviral medications like valacyclovir, acyclovir, and famciclovir are effective in reducing symptoms and shortening the duration of outbreaks 1.
- Suppressive therapy with lower daily doses may be recommended for frequent recurrences, such as acyclovir 400mg twice daily or valacyclovir 500mg daily 1.
- Over-the-counter options like docosanol cream (Abreva) and pain relievers like acetaminophen or ibuprofen can help manage symptoms.
- Home remedies like applying ice to reduce pain, avoiding triggers like stress and sun exposure, maintaining good hygiene, and using lip balm with sunscreen can also help manage symptoms. It's crucial to seek medical attention for severe symptoms, frequent recurrences, or if you have a weakened immune system, as oral herpes can cause significant morbidity and mortality in immunocompromised patients 1.

From the Research
Oral Herpes Treatment Options
- Antiviral medications such as acyclovir, valacyclovir, and famciclovir are effective in treating oral herpes infections 3, 4, 5, 6.
- Topical antiviral creams, such as 5% acyclovir cream, can reduce the duration of lesions if applied early 4.
- Systemic antiviral medications, such as acyclovir 400 mg three times a day or valacyclovir 500-1000 mg twice a day, can effectively treat recurrent oral herpes infections 4.
Treatment Efficacy
- Valacyclovir has been shown to be as effective as acyclovir in treating genital herpes and herpes zoster, with the added benefit of a more convenient oral dosage regimen 5, 6.
- Famciclovir and valacyclovir appear to decrease the time to resolution of pain compared to acyclovir in patients with herpes zoster infections 7.
- Valacyclovir is the only oral antiviral agent approved for therapy of herpes labialis, and is also approved for a 3-day course in the episodic treatment of recurrent genital herpes 6.
