MHRA-Approved Cold Sore Treatments Available
Recognising Early Cold Sore Symptoms
The first stage of a cold sore outbreak typically involves a tingling, burning, or itching sensation around the lips or mouth area. This prodromal phase occurs 1-2 days before visible blisters appear and represents the optimal treatment window. Other early warning signs may include slight swelling, tenderness, or a feeling of tightness in the affected area.
Antiviral Treatment Options
Aciclovir remains the gold standard for cold sore treatment, available in both oral and topical formulations. Aciclovir 400mg tablets can significantly reduce healing time when taken at the first sign of symptoms, typically prescribed as one tablet three times daily for five days. Topical aciclovir 5% cream offers an alternative approach, applied five times daily to the affected area.
Valaciclovir 500mg tablets represent another effective option, often requiring less frequent dosing than standard aciclovir. This prodrug converts to aciclovir in the body, potentially offering improved bioavailability and convenience with twice-daily dosing regimens.
Treatment Timing and Effectiveness
Research indicates that antiviral treatments are most effective when initiated within 24-48 hours of symptom onset. Starting treatment during the tingling phase can reduce the duration of an outbreak by 1-2 days and may prevent progression to the blister stage entirely in some cases. Delayed treatment initiation typically results in diminished therapeutic benefits.
