What can you buy without a prescription for cold sores in England?

Products to ask about

Use the term cold sore at a British pharmacy. A pharmacist may offer an antiviral cream, a product for pain or irritation, or a protective patch. The NHS ↗ notes that antiviral cream is more useful when started at the familiar early tingling stage; it may be less effective once blisters appear.

Mention age, pregnancy, medical conditions and previous treatment. If seeking an alternative to an overseas product, show the packaging and check the ingredient and instructions rather than relying on a similar brand name.

What a purchase can achieve

A patch protects damaged skin but does not remove the virus from the body. One course cannot promise that the problem will never return. Frequent or severe outbreaks are a reason to discuss a medical plan rather than repeatedly switching cosmetic products.

Before paying, clarify pack price, treatment duration and whether the product is suitable for the affected area. A lip treatment must not automatically be used near the eyes or on other mucous membranes. A pharmacist ↗ can explain application and interactions.

Preventing transmission

Cold sores are infectious from early tingling until completely healed. Avoid kissing and oral sex during this time, and wash your hands after touching the area. In particular, do not kiss a newborn: infection can be dangerous for a baby.

Do not pick the scab or apply irritating homemade mixtures. Do not share a product that touches affected skin.

When to seek medical care

See a GP if healing has not started within 10 days, the sore is very large or painful, there are painful gums and mouth ulcers, or you have a weakened immune system. A clinician can review the diagnosis and whether prescription treatment is appropriate.

For eye pain or redness, altered vision or uncertainty about urgency, use 111 ↗ to find the right service today. Do not put lip cream in an eye or wait for your usual treatment to work.
