Yes — cold sores (oral herpes / HSV-1 flare-ups) are commonly treated through telemedicine.

Most cases can be safely evaluated based on symptoms, history, and a visual exam (video or photos), and treatment can be prescribed when appropriate.

✅ What telemedicine can usually do

During a virtual visit, the clinician can:

• Confirm the rash is likely a cold sore

• Review onset, triggers, and recurrence pattern

• Check your medical history & medications

• Provide prevention and outbreak counseling

• Prescribe antiviral medication when needed

Commonly prescribed options (case-by-case):

• Valacyclovir (Valtrex)

• Acyclovir

• Famciclovir

These work best when started at the first sign of tingling, burning, or swelling.

Many providers will also prescribe a standing prescription for future outbreaks so you can start treatment early.

🧴 Supportive / over-the-counter options

Telemedicine providers may also recommend:

• Docosanol (Abreva)

• Petroleum jelly to protect the lesion

• Avoiding picking, friction, or kissing

• Hand-washing to prevent spread

⚠️ When an in-person exam may be needed

Seek urgent or in-person care if you have:

• Cold sores spreading to the eye

• Severe facial swelling or high fever

• Large or persistent sores (>2–3 weeks)

• Frequent outbreaks (≥6 per year)

• Immune-compromising conditions

• Unsure if it might be shingles or impetigo

Babies, pregnant patients, and people on chemotherapy or steroids may need closer evaluation.
