Managing Cold Sores: Prevention and Treatment in The Southern Highlands

Expert advice from your pharmacist on soothing the sting and speeding up recovery

Cold sores are incredibly common in Australia, with approximately 75% to 80% of adults carrying the virus that causes them. According to Healthdirect, most people are first infected during childhood, often without even realising it. While these small, fluid-filled blisters are usually harmless for most people, the tingling, itching, and visible nature of an outbreak can cause significant discomfort and self-consciousness.

The Southern Highlands climate—with its crisp winters and bright, high-UV summers—can often provide the perfect environmental “triggers” for a dormant virus to wake up. Whether it’s windburn from a walk through Moss Vale or a simple bout of fatigue, understanding how to manage cold sores effectively is the first step toward faster healing and fewer outbreaks.

At Moss Vale Community Pharmacy, we provide a range of over-the-counter medicines and expert guidance to help you manage the virus. This article outlines what causes cold sores, how to recognise the early signs, and the best ways to protect yourself and your family.

What are Cold Sores?

Cold sores, often called “oral herpes,” are small, painful blisters that typically appear on or around the lips, chin, or nose. They are caused by the Herpes Simplex Virus (HSV). Once you are infected with the virus, it remains in your body for life, resting in the nerve cells near the site of the original infection.

Most of the time, the virus is “dormant” (inactive). However, certain factors can cause it to “reactivate,” travelling back down the nerve to the skin’s surface and forming a blister. While there is currently no cure to eliminate the virus from the body entirely, modern treatments can significantly reduce the duration of an outbreak and ease the pain.

The Two Types of Herpes Simplex

There are two main types of the virus. While they were historically associated with different parts of the body, we now know that both types can cause sores in either location.

Causes and Triggers

The initial infection usually occurs through direct physical contact with someone who has an active sore or contact with their bodily fluids (saliva). This includes kissing, skin-to-skin contact, or sharing items like toothbrushes, towels, and drink containers.

Common Outbreak Triggers

Once the virus is in your system, various factors can “trigger” it to become active again. These vary from person to person but often include:

• Environmental Factors: Exposure to strong sunlight, wind, or cold weather (common in the Southern Highlands).
• Physical Stress: Fatigue, illness (like the common cold or flu), or local injury to the mouth or skin.
• Hormonal Changes: Many women find that menstruation can trigger an outbreak.
• Emotional Stress: High levels of anxiety or emotional upset can weaken the immune system’s ability to keep the virus dormant.

Signs and Symptoms

An outbreak usually follows a predictable pattern over 7 to 12 days:

1. Tingling and Itching: The area feels hot or “buzzy” for about 24 hours.
2. Blister Formation: Small, fluid-filled blisters emerge.
3. Weeping/Crusting: The blisters may burst or ooze, eventually forming a yellow or brown crust or scab.
4. Healing: The scab falls off, usually leaving the skin pink or slightly tender before returning to normal. Cold sores typically do not leave scars.

During a first-time infection, symptoms can be more severe and may include fever, headache, sore throat, or swollen glands.

The Role of Your Pharmacist in Cold Sore Care

Your pharmacist is your most accessible resource for cold sore management. At Moss Vale Community Pharmacy, we can help you choose the right treatment based on the stage of your outbreak and your medical history.

Prevention and Self-Management

While you can’t cure the virus, you can take steps to reduce the number of outbreaks you experience and stop the spread:

• Sun Protection: Use a lip balm with SPF 30+ or 50+ whenever you are outdoors, as UV light is a major trigger.
• Hand Hygiene: Always wash your hands after applying cream to a cold sore or if you accidentally touch it.
• Avoid Triggers: If you know that stress or lack of sleep causes your cold sores to flare, prioritise rest and stress-management techniques.
• Don’t Share: Keep your own towels, cutlery, and lip products during an outbreak.

When to See Your Doctor

Most cold sores heal within two weeks without treatment. However, you should consult your GP if:

• The cold sore has not healed after two weeks.
• The sores are very large, deep, or unusually painful.
• The cold sore is spreading or you have multiple sores.
• The cold sore is near your eye (this can lead to serious complications if the virus affects the cornea).
• You have a weakened immune system (e.g., due to chemotherapy, HIV, or certain medicines).
• You suffer from frequent outbreaks (more than 6 times a year).
