Cymex Cream is a licensed over-the-counter cold sore treatment containing cetrimide and dimethicone, available without a prescription for adults and children aged over 12. The formulation works as a barrier cream that softens and soothes the affected area while the active ingredient cetrimide provides antiseptic action during the cold sore healing cycle. Cymex is manufactured by Goldshield and is one of the longer-established cold sore creams available in Ireland, making it a recognised name alongside products such as Zovirax; unlike Zovirax, which contains the antiviral aciclovir, Cymex acts primarily as a soothing barrier and antiseptic rather than an antiviral agent. Cymex is applied to the affected area up to five times daily at the first sign of a cold sore. Always read the patient information leaflet before use, and speak with your pharmacist if you are unsure whether this product is appropriate for your needs. Ronaghan's Pharmacy stocks Cymex Cream alongside a broader range of Lip Skincare products suited to everyday lip comfort and protection.
