The antiviral spray provides four hours of protection with each application, the manufacturer claimed, and it is suitable for adults and children over one year of age.

which provides effective moisturisation of the nasal cavity, so unlike some nasal sprays there is no irritation or stinging on application or drying out of the nose. Its unique thixotropic formulation increases viscosity during application, transforming the liquid spray into a thin, soft, barrier film which has excellent adherence to the nasal mucosa surface. This results in prolonged anti viral activity (4 hours protection with each application4), precise dosage of only 1 spray per nostril, and no nasal drip. Chirico G, Quatarone G, Mallefet P.

The anti viral ingredients include the natural anti virals kappa-carrageenan and fucoidan (red and brown seaweeds) which are proven to disrupt virus attachment, absorption, and its replication process; xylitol, a sugar carbohydrate which helps inhibit virus and bacteria adhesion; diterpenoid, a natural anti-inflammatory and siberian fir oil, an anti-inflammatory and a natural decongestant.Nguyen S, Psaltis A, Schlosser R.

Frontiers Neurol. 2021;12. doi:10.3389/fneur.2021.794471 Nasofed Anti Viral Nasal Spray has not been tested against COVID-19, and therefore does not make claims to prevent it, the manufacturer stressed. Anti Viral Nasal Spray is not a substitution for vaccines, face masks, social distancing or other COVID-19 measures

When used, the liquid contained in the Nasofed Anti Viral Nasal Spray is transformed “into a thin, soft and long-lasting protective film on the nasal mucosa surface, creating an effective barrier against virus particles, while delivering an accurate dose of broad spectrum anti-viral ingredients”, according to the manufacturer.
