Your Guide to Cold Sore
Updated · Checked by our editorial team
How to choose
Turnaround time is the deciding factor. Antivirals work best when started at the first tingle, so compare how quickly a service reviews intake and gets a prescription to your pharmacy, and whether it offers a supply to keep on hand for future outbreaks.
How it works
Complete a short intake describing symptoms and outbreak history, have a licensed clinician review it, and receive an antiviral prescription for the current outbreak or as an on-hand supply.
What to confirm
- Prescriptions issued fast enough to matter at the prodrome stage
- Option to keep an on-hand supply for future outbreaks
- Suppressive therapy for people with frequent recurrences

Frequently Asked Questions
Answers to common questions about cold sore.
What medication treats cold sores?
Oral antivirals such as valacyclovir, acyclovir and famciclovir are the standard treatment. They shorten an outbreak most effectively when started during the tingling or burning prodrome, before the blister appears.
What causes cold sores?
Cold sores are usually caused by herpes simplex virus type 1, which stays dormant in nerve tissue after the first infection and reactivates periodically. Common triggers include illness, fever, sun exposure, stress and fatigue.
Can cold sores be prevented?
People with frequent recurrences can be prescribed daily suppressive antiviral therapy, which reduces how often outbreaks occur. Sun protection on the lips and managing known triggers helps for those with milder patterns.
