Common cold and flu-like illnesses are caused by a large variety of viruses, such as rhinoviruses, coronaviruses, and others. If viruses have penetrated into the nose, they can attach themselves to the mucous membrane and infect mucosal cells where they multiply and spread.
Agovirax® Nasal Spray creates a protective barrier on the nasal and oral mucosa thus preventing binding and entry of the respiratory viruses into the cells. Thereby viruses cannot attach to the mucosal cells and infection is stopped.
Iota-carrageenan (active substance of Agovirax) inhibits the cell entry of SARS-CoV-2. The latest in vitro study confirmed, that “iota-carrageenan inhibits the cell entry of SARS-CoV-2 (…), which suggests that administration of iota-carrageenan may be effective and safe prophylaxis or treatment also for SARS-CoV-2 infections“. 
Iota carrageenan creates a protective barrier on the nasal and oral mucosa thus preventing binding and entry of the respiratory viruses, including coronaviruses, into the cells.
Use each time before being exposed to potential viruses.
