About Zovirax
Zovirax is Britain's most trusted cold sore treatment, delivering clinically proven results through its active ingredient aciclovir. Now part of the Haleon consumer healthcare family after spinning off from GSK in 2022, Zovirax has been helping people fight cold sores for decades with its targeted antiviral formula that works at the source of infection. The science behind Zovirax is straightforward but powerful. The cream contains 5% aciclovir, an antiviral compound that blocks the replication of herpes simplex virus - the cause of cold sores. Unlike treatments that only address symptoms, Zovirax tackles the virus itself, with clinical studies involving over 1,385 participants showing mean healing times of 4.6 days compared to 5 days with placebo treatments. Zovirax Cold Sore Cream is formulated with a special penetration enhancer that delivers aciclovir deep into the skin where the virus resides. Each 2g tube provides enough cream for 3-4 cold sore attacks, making it an economical medicine cabinet essential. The treatment should be applied five times daily at four-hourly intervals, starting at the first tingle for best results. Available without prescription from pharmacies and supermarkets across the UK including Boots, Tesco, and Sainsbury's, Zovirax comes in both tube and convenient pump formats. Suitable for adults and children, Zovirax remains the gold standard in over-the-counter cold sore treatment, combining pharmaceutical-grade efficacy with the accessibility that millions of sufferers need when a cold sore strikes.
