Common questions

Cold sores, answered.

General information, not medical advice. A provider can answer questions about your situation.

Can you get cold sore treatment online?

Yes, cold sores are often handled in virtual visits because they are easy to describe and photograph. A provider may prescribe treatment if appropriate.

Are cold sores contagious?

Yes, especially from the first tingle until the sore has fully crusted and healed. Avoid kissing, sharing cups or lip products, and contact with babies during an outbreak.

How long do cold sores last?

Most cold sores heal in about one to two weeks. If one lasts longer or you get them often, talk with a provider.

This is not for emergencies.

For life-threatening symptoms, severe chest pain, trouble breathing, or immediate danger, call 911 or go to the nearest emergency department.
