Can telemedicine treat Cold Sores (Herpes Labialis)?

Audience: adult

Cold sores, also known as herpes labialis, are small, painful blisters that usually appear on or around the lips. They are caused by the herpes simplex virus and often clear up on their own within a couple of weeks. Telemedicine can help you get advice on managing cold sores, including recommendations for over-the-counter remedies or prescription antiviral medications. A healthcare provider can assess your symptoms through a video or phone visit and guide you on how to reduce discomfort and prevent spreading the virus. However, some cases require in-person care, especially if sores worsen or do not heal as expected. Telemedicine is a convenient way to get timely support, but it is important to watch for warning signs that need urgent medical attention.

Red flags — go in person / ER

• Cold sores lasting more than 2 weeks without improvement — seek in-person medical evaluation.
• Severe pain, swelling, or spreading redness around the sores — get urgent medical care.
• Eye symptoms such as redness, pain, or vision changes — seek emergency eye specialist evaluation.

What telemedicine can do

• Initial assessment of cold sores through video or phone consultation.
• Advice on over-the-counter treatments and prescription antiviral medications.
• Guidance on preventing spread and managing symptoms at home.
• Monitoring mild to moderate cases and follow-up consultations.

What telemedicine cannot do

• Severe or worsening cold sores requiring physical examination.
• Suspected bacterial infection needing laboratory tests or antibiotics.
• Eye involvement or complications requiring specialist care.
• Cold sores in people with weakened immune systems needing complex management.

What Are Cold Sores (Herpes Labialis)?

Cold sores are caused by the herpes simplex virus (usually HSV-1). They appear as clusters of small blisters on or around the lips. These blisters can be painful and may break open, forming crusts before healing. Cold sores are contagious and spread through close personal contact, such as kissing or sharing utensils. After the first infection, the virus stays in the body and can reactivate, causing new cold sores, often triggered by stress, illness, or sun exposure.

How Telemedicine Can Help With Cold Sores

Through telemedicine, you can consult a healthcare provider without going to a clinic. Providers can visually assess your cold sores via video and discuss your symptoms. They may recommend treatments such as antiviral creams or oral medications to speed healing and reduce pain. Telemedicine can also offer advice on how to prevent spreading the virus to others and how to manage triggers. This approach is convenient, especially when you need quick guidance or cannot easily visit a healthcare facility.

When Telemedicine May Not Be Enough

Some situations require in-person medical evaluation. If cold sores are severe, very painful, spreading widely, or not healing after two weeks, you should see a healthcare provider in person. Also, if you have a weakened immune system, eye involvement, or signs of bacterial infection (like increased redness, swelling, or pus), urgent face-to-face care is necessary. Telemedicine cannot perform physical tests or procedures, so it cannot replace emergency or specialized care.
