Why Choose VIRALEZE™ Antiviral Nasal Spray?
Your First Line of Defence Against Viral Infections
The Power Behind The Protection
Astodrimer sodium forms an invisible barrier in the nose. It works by physically trapping and blocking respiratory virus particles in the nose, reducing viral load and increasing the rate of viral clearance (References: 1,2,3).

FAQs
VIRALEZE™ contains astodrimer sodium, a patented ingredient proven in laboratory studies to trap and block cold and respiratory viruses. The formulation provides a protective moisture barrier in the nose, helping to reduce viral adhesion, multiplication, and spread, allowing your body’s natural defences to remove the viruses.
Astodrimer sodium is a large molecule with multiple negative surface charges. These negative charges serve as sites of engagement with positively charged regions of viral spike proteins and other viral attachment proteins. The electrostatic interaction between astodrimer sodium and the viral attachment proteins is strong due to the polyvalent structure of astodrimer sodium, and is not specific, leading to the ability to block a broad spectrum of respiratory viruses.
To ensure the action of VIRALEZE™ is not affected, we recommend that VIRALEZE™ not be applied immediately before or after other nasal products. If you intend to use VIRALEZE™ with other nasal spray products, we recommend allowing 3-4 hours after applying VIRALEZE™ before applying another product to ensure the barrier function of VIRALEZE™ is not compromised. Consult your healthcare provider for advice if you are using other nasal treatments.
VIRALEZE™ can be used by adults and children aged 12 years and over.
Some users may experience mild effects such as a stuffy nose or a transient tingling sensation in the nose following application. These effects are expected and not of concern. If you experience severe discomfort, stop use and consult your healthcare provider.
VIRALEZE™ can be used before or after being in crowded environments to help reduce viral load in the nasal cavity.
To use VIRALEZE™, gently blow your nose to clear your nasal passages, wash your hands, and remove the bottle’s protective cap.
If necessary, prime the bottle by spraying VIRALEZE™ one or more times into the air or a tissue until a fine mist is dispensed.
Close one nostril by pressing on that side of your nose, and gently insert the nozzle into the other nostril, pointing it away from the centre of your nose. Press down on the pump to activate the spray while gently breathing in (normal breathing). You don’t need to take a deep breath when applying the nasal spray.
Repeat for the other nostril.
Yes, it is recommended to blow your nose with a tissue before applying VIRALEZE™.
Consult your healthcare provider before using VIRALEZE™ if you are pregnant or breastfeeding, or planning to become pregnant or to breastfeed.
Shield yourself and the ones you love.
Use VIRALEZE™ as an extra protective measure in your defence against respiratory viruses.
