Herpes und Fieberbläschen

Cold sores are an infection usually caused by the herpes simplex virus type 1 (HSV-1). They typically manifest as small vesicles or blisters clustered around the lips, although they can also affect nearby areas.

After the initial infection, the virus can remain dormant in the body and later reactivate, causing new outbreaks. For this reason, some people experience recurrent cold sores on their lips.

Before the blisters appear, it is common to experience certain sensations in the area where the outbreak will develop. Recognising these early signs allows you to start the recommended care or treatment for each product as soon as possible.

Common symptoms include:

• A tingling or itching sensation around the lip.
• A burning or stinging sensation.
• Redness in the area.
• The appearance of small fluid-filled blisters.
• Localised discomfort or tenderness.
• Subsequent formation of a scab as the outbreak progresses.

Once the virus remains dormant in the body, certain factors can trigger its reactivation. Triggers can vary from person to person.

Factors commonly associated with the onset of a cold sore include:

• Intense exposure to the sun.
• Stress and tiredness.
• Fever or certain infections.
• Hormonal changes.
• Weakened immune system.
• Sores or irritation on the lips.

There are various products available for cold sores which can be used depending on the stage of the outbreak and the specific characteristics of each case. These may include topical antiviral medicines, where indicated, as well as plasters and products designed to protect the lesion.

It is important to distinguish between medicines and skincare products. Always check the instructions on the packaging and the patient information leaflet and, if in any doubt, seek advice from a pharmacist.

Cold sore creams may contain medicines with antiviral active ingredients specifically authorised for the treatment of certain herpes simplex infections.

The method of application and duration of treatment depend on the specific medicine. Some treatments are particularly effective when used during the early stages of an outbreak, so you should follow the instructions set out in the patient information leaflet.

Cold sore patches cover the lesion and create a physical barrier over the affected area. Depending on the product, they can help protect the cold sore from contact and reduce accidental touching.

Their discreet design means they can be worn during everyday activities, and some types are virtually invisible once applied.

Cold sore outbreaks usually progress through different stages until they clear up. The treatments available can help to manage the outbreak or its symptoms, but they do not permanently eliminate the virus from the body.

When a cold sore appears on the lip, it is important to avoid picking at or removing the scabs and to maintain good hygiene in the area. If you are using medication, follow the frequency and duration of application as set out in the package leaflet.

The duration can vary from person to person and between different outbreaks. Usually, a cold sore goes through an initial phase of tingling, followed by the appearance of blisters, which then burst, and the formation of a scab until it heals.

If the lesions do not improve, last longer than usual or get worse, consult a healthcare professional.

Yes. Cold sores are contagious and can be transmitted through direct contact with the sores or secretions of an infected person. The risk of transmission may exist during different stages of the outbreak.

To reduce the risk of transmission, it is advisable to take certain precautions:

• Do not touch the sores unnecessarily.
• Wash your hands after applying any product to the affected area.
• Do not share lip balms, glasses, cutlery or towels during an outbreak.
• Avoid kissing or having direct contact with the sore.
• Avoid touching your eyes after touching the affected area.

In some people, intense exposure to sunlight can trigger new outbreaks. Using a lip balm with sun protection can form part of the skincare routine for those who identify the sun as a factor associated with their recurrent episodes.

Protecting your lips is particularly important during the summer, when taking part in outdoor activities, or in areas with high levels of solar radiation.
