Frequently Asked Questions

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.

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.

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.
