Understanding Cold Sore Triggers and Avoidance
Foods and Drinks to Avoid During a Cold Sore Outbreak
Certain foods can irritate cold sores in your mouth and delay healing. Acidic foods such as citrus fruits, tomatoes, pickles, and fizzy drinks may cause stinging and discomfort. Spicy foods containing chilli or hot peppers can also aggravate the affected area. Salty snacks like crisps or nuts may irritate the sensitive tissue around the cold sore. Additionally, very hot foods and beverages should be consumed with caution as they may cause pain and potentially slow the healing process.
Activities and Behaviours to Avoid
Touching or picking at a cold sore is one of the most important things to avoid. This can introduce bacteria, leading to secondary infections, and may also spread the virus to other parts of your body or to other people. Avoid kissing or intimate contact whilst the cold sore is active, as this is when transmission risk is highest. Don't share personal items such as lip balm, cutlery, glasses, or towels during an outbreak. Over-brushing the affected area should also be avoided to prevent further irritation.
Environmental Factors to Consider
Sun exposure can trigger cold sore outbreaks and worsen existing ones. Avoid prolonged exposure to UV light without proper lip protection containing SPF. Wind and cold weather can also irritate cold sores, so consider using a protective lip balm when outdoors. Stress is a known trigger for cold sore outbreaks, so avoiding unnecessary stress where possible may help prevent recurrence.
Treatment Options Available
Aciclovir tablets, such as the 400mg formulation available through EverydayMeds, may help reduce the duration and severity of cold sore outbreaks when taken early. Topical aciclovir cream can also provide localised treatment. For some patients, valaciclovir tablets may be prescribed as an alternative antiviral option. These prescription treatments work by interfering with viral replication and are most effective when started at the first sign of symptoms.
