Betadine® Nasal Defence – Product Overview

Betadine® Nasal Defence is a medical nasal spray developed to help support the natural defence of the nasal cavity against respiratory viruses. The product forms a protective barrier on the nasal mucosa, which is the primary entry point for many airborne pathogens responsible for common colds and flu-like illnesses.

The formulation is designed for regular daily use during periods of increased exposure to respiratory infections, such as seasonal outbreaks, crowded environments, travel, and workplace settings.

Betadine® Nasal Defence is intended for educational and preventive support purposes and does not replace medical diagnosis or professional treatment.

How Betadine® Nasal Defence Works (Mechanism of Action)

Respiratory viruses commonly enter the body through the nasal mucosa. The nasal epithelial surface represents one of the first and most important contact points between inhaled pathogens and the human immune system.

Betadine® Nasal Defence acts by creating a protective micro-barrier on the surface of the nasal lining. This barrier supports the natural defensive function of the nasal mucosa and helps reduce the interaction between viruses and nasal epithelial cells.

By reinforcing the nasal surface, the product supports early-stage defence before viruses can attach to and penetrate the nasal epithelium.

Scientific Evidence

The nasal epithelium is recognized as a primary site of viral attachment and replication in respiratory infections.
