From the Guidelines
For the treatment of Herpes Simplex Labialis, also known as cold sores, the most effective approach is to use antiviral medications, either topical or oral, as soon as symptoms appear, to reduce the duration and severity of outbreaks. The treatment options include over-the-counter topical antivirals, such as docosanol or benzyl alcohol, which can be applied 5 times daily for 4-5 days, or prescription oral antivirals like valacyclovir or acyclovir, which can be highly effective if started early 1. Some key points to consider when treating cold sores include:
- Applying ice packs for 15 minutes every hour to reduce swelling and pain
- Taking acetaminophen or ibuprofen for pain relief
- Keeping the area clean and dry
- Avoiding touching or picking at the sore to prevent bacterial infection and spreading the virus
- Starting antiviral medications at the first sign of symptoms, as they are most effective when initiated early
- Considering daily suppressive therapy with oral antivirals for frequent outbreaks (more than 6 per year) to reduce recurrence frequency, as discussed in the context of current management and recommendations for access to antiviral therapy of herpes labialis 1. It's essential to note that while these treatments can significantly shorten healing time and provide symptom relief, they do not cure the underlying herpes simplex virus infection.

From the Research
Treatment Options for Herpes Simplex Labialis (Cold Sore)
The treatment options for Herpes Simplex Labialis (cold sore) include:
- Antiviral medications such as valacyclovir and acyclovir 3, 4, 5
- Topical treatments like aciclovir cream 6
- Hygiene measures to avoid transmitting the virus 6
Antiviral Medications
Antiviral medications are the typical treatment for cold sores, with valacyclovir and acyclovir being the most commonly prescribed medications 3, 4, 5.
- Valacyclovir has been shown to be effective in reducing the duration of cold sore episodes and preventing lesion development 3, 7
- Acyclovir is also effective in treating cold sores, but valacyclovir has been found to have better bioavailability and greater plasma concentrations of acyclovir 3, 5
Topical Treatments
Topical treatments like aciclovir cream can be used to treat cold sores, but the addition of hydrocortisone to aciclovir has not been found to be more effective than aciclovir alone 6.
- The use of hydrocortisone in combination with aciclovir is not recommended due to the potential risks associated with corticosteroids 6
Treatment Regimens
Different treatment regimens have been studied, including a 1-day valacyclovir treatment regimen which has been found to be safe and effective 3, 7.
- The 1-day valacyclovir regimen offers patients a unique and convenient dosing alternative compared to available topical therapies 3
