Nasofed Anti Virus Nasal Spray features unique thixotropic properties which transform the liquid spray into a thin, soft, protective film on the nasal mucosa surface, creating an effective and long-lasting barrier against external factors including virus particles, while delivering an accurate dose of scientifically proven anti-viral ingredients. These unique thixotropic properties also prevent the solution running off the surface of the nose, giving a longer-lasting protective film than conventional nasal sprays.
