Understanding Nasal Cold Sores: Causes & Treatment
What Causes Cold Sores on the Nose?
Cold sores on the nose develop when the herpes simplex virus type 1 (HSV-1) reactivates from its dormant state in nerve cells. Up to 70% of the UK population carries HSV-1, though many never experience symptoms. The virus may reactivate due to stress, illness, sun exposure, or a weakened immune system, causing blisters to appear on the nose, nostrils, or surrounding skin.
The 5 Stages of Nasal Cold Sores
Stage 1 (Days 1-2): Tingling, itching, or burning sensation around the nose. This is the optimal time to begin antiviral treatment. Stage 2 (Days 2-4): Small, fluid-filled blisters appear on the nose. Stage 3 (Days 4-5): Blisters burst and weep, making this the most contagious phase. Stage 4 (Days 5-8): Scabs form over the sores. Stage 5 (Days 8-10): Healing completes as scabs fall off naturally.
Treatment Options Available
Antiviral medications may help reduce the severity and duration of cold sore outbreaks when started early. Aciclovir tablets (400mg) are commonly prescribed for cold sore treatment, typically taken five times daily for five days. Topical aciclovir 5% cream may also be applied directly to the affected area. EverydayMeds offers aciclovir tablets and cream, plus alternative antivirals like valaciclovir for those seeking convenient online access to cold sore treatments.
Prevention and Management
Avoid touching the cold sore and wash hands frequently to prevent spreading the virus to other areas or people. Use separate towels and avoid sharing drinks or utensils during an outbreak. Sun protection may help prevent future outbreaks, as UV exposure can trigger HSV-1 reactivation. Those experiencing frequent outbreaks should consult their GP about suppressive antiviral therapy options.
