Cold sores are small, painful blisters that usually appear on or around the lips. They are caused by the herpes simplex virus (HSV-1) and can flare up when your immune system is low, during stress, or after too much sun exposure. At Lygon Everyday Chemist in Brunswick East, we often see customers looking for safe, effective, and fast relief.

In this blog, we’ll answer the most ask questions about cold sores at Lygon everyday chemist ,plus share treatment options, foods to eat and avoid, and how our pharmacy team can support you.

What causes cold sores?

Cold sores are caused by HSV-1, which stays dormant in your body after the first infection. Triggers include:

• Stress and fatigue
• Weakened immune system
• Hormonal changes
• Illness (like colds and flu)
• Sunburn or extreme weather

How do you treat a cold sore fast?

While there’s no cure, treatment can shorten healing time and ease discomfort. 

Options include:

• Antiviral creams (e.g. aciclovir) – apply at the first tingle for best results.
• Antiviral tablets – may be recommended for frequent or severe outbreaks.
• Cold sore patches – protect the sore and help healing.
• Pain relief gels or creams – soothe pain and dryness.

At Lygon Everyday Chemist, our pharmacists can recommend the right option for you, including prescription-strength treatments if needed.

What foods make cold sores worse?

Certain foods may trigger or worsen outbreaks because they contain arginine, an amino acid that helps the virus replicate. 

Foods to limit or avoid during a flare-up include:

• Chocolate
• Nuts (especially peanuts, almonds, and walnuts)
• Seeds (sunflower, sesame)
• Oats

What foods help heal cold sores?

Foods rich in lysine may help slow viral replication, while immune-boosting nutrients support recovery.

Helpful options include:

• Dairy (yoghurt, cheese, milk)
• Fish and chicken
• Eggs
• Vegetables (especially leafy greens)
• Fruits rich in vitamin C (oranges, kiwi, strawberries)

Do vitamins help with cold sores?

Yes – vitamins and supplements can reduce frequency and severity:

• Lysine supplements – may prevent outbreaks and support healing.
• Vitamin C & Zinc – boost immune response.
• Vitamin E – helps repair skin.
• Probiotics – support gut health and immunity.

We stock a wide range of immune-supporting vitamins at Lygon Everyday Chemist and can help match the right one for your needs.

Can cold sores spread?

Yes – they are contagious, especially when blisters are open. 

Avoid:

• Kissing or close contact
• Sharing cutlery, cups, or lip balm
• Touching the sore then touching eyes or genitals

When should you see a doctor?

Seek medical advice if:

• Cold sores occur very often
• Sores don’t heal within 10 days
• You experience severe pain or fever
• The infection spreads to other areas

Our pharmacists can advise when a GP referral is needed.
