Cold Sore Care

What is a cold sore:
A cold sore, also known as a fever blister, is a common viral infection caused by the herpes simplex virus type 1 (HSV-1). These tiny, fluid-filled blisters typically appear on or around the lips. Cold sores are not canker sores.


Here are some key points about cold sores:


Symptoms:

  • Tingling and itching: Many people feel itching, burning, or tingling around the lips before blisters form.

  • Blisters: Small fluid-filled blisters often appear along the lip border or around the nose and cheeks.

  • Oozing and crusting: Blisters may merge, burst, and leave shallow open sores that ooze and crust over.

Causes:

  • HSV-1: Cold sores are primarily caused by HSV-1, which can spread through close contact (e.g., kissing) or sharing items like utensils and towels.

  • Spread: The virus can spread by contact even if no visible sores are present.

Treatment and Prevention:

  • Helocaine® treat the cold sore in as little as 12 hours and eliminate the pain immediately

  • Other Name brands: Just treat the cold sore or the pain, but not at the same time, and usually take 2x longer to treat.

  • Antiviral drugs: Prescription antiviral medicine only treat the virus and still take 2x longer to treat.

  • Self-care: Avoid touching, rubbing, or scratching the sores. Use moisturizing creams to prevent dry lips.

  • Preventive measures: Avoid contact with infected individuals and shared items during outbreaks.
