Zovirax (Acyclovir Cold Sore Cream)

Zovirax is a globally recognized antiviral treatment, primarily used for managing cold sores and herpes simplex virus infections. Originally developed with the active ingredient acyclovir, the brand became a staple in domestic medicine cabinets as a trusted over-the-counter and prescription solution for viral outbreaks. Its history is deeply rooted in significant medical breakthroughs within the pharmaceutical industry of the late 20th century.

The manufacturing of Zovirax occurs across a global network of specialized pharmaceutical facilities to meet international demand. Significant production centers are located in countries such as the United Kingdom and Germany, though specific local markets may be supplied by regional manufacturing branches of its parent company. This ensures widespread availability and compliance with different healthcare regulatory standards across the globe.

Ownership of the Zovirax brand has transitioned through major corporate restructuring in the healthcare sector. While originally developed by Burroughs Wellcome, it eventually fell under the GSK (GlaxoSmithKline) portfolio. In 2022, GSK spun off its consumer healthcare division into a new independent entity known as Haleon. As of 2024 and looking toward 2026, Haleon serves as the ultimate owner, focusing exclusively on consumer health products and maintaining Zovirax as one of its flagship brands.
