Zovirax Cream contains aciclovir, an antiviral medicine that works by stopping the herpes simplex virus from multiplying. When applied early—at the first tingling or itching sensation—it can help reduce the severity and length of a cold sore outbreak.

The cream is applied directly to the affected area at regular intervals throughout the day, as directed in the patient information leaflet. It is for external use only and should not be applied inside the mouth, nose, or eyes.

If cold sores do not improve within 10 days, or if they become more frequent or severe, seek advice from a healthcare professional. Always read the patient information leaflet before use.
