The mechanical mode of action of PIRDAL Nasal Spray makes it possible to detach all types of viruses and contaminants (bacteria, dust, foreign particles) present on the nasal mucosa.

Yes, virus variants have no impact on the efficacy of PIRDAL because PIRDAL acts by its mechanical mode of action: a patented filmogen barrier that is able trap and detach viruses regardless of variants.

The filmogen formed on the nasal mucosa is estimated to last approximately 4 hours.

PIRDAL forms a protective filmogen on the nasal surface upon application. It is fully effective 15 minutes after application.

Use it whenever you have to go to a high-risk area (confined, crowded, or places with poor air ventilation), up to 4 times a day if necessary.

Do not use PIRDAL for more than 30 days consecutively. If necessary, take a break from using it for a few days before using it again. (In all cases, please refer to user instructions).

No, PIRDAL is formulated with only food- and plant-based ingredients. The filmogen also stays on the surface and is not absorbed by the body.

PIRDAL Nasal Spray is safe for most individuals (Please refer to user instructions). 

For those who are pregnant or breastfeeding however, it’s best to seek advice from a medical professional.

In the event of infection, Pirdal does not prevent transmission.

It is strongly advisable to use PIRDAL at public spaces such as workplaces, hospitals and clinics, schools, shopping centers, markets, public transport, restaurants, gyms and gatherings, and especially during times like dining out when you need to take off your face masks, and individuals who frequent the hospitals or medical centers.

Yes, because PIRDAL is not absorbed by the body. However, for better effectiveness, we advise you not to use other nasal sprays for at least 30 minutes before using PIRDAL.

Yes, it is possible because PIRDAL attracts hypotonic fluid from the nasal mucosa, which can sometimes trigger a runny nose and generate a slight temporary nasal irritation. This is normal and related to the product’s mechanical mode of action. These effects should go away within 15-20 minutes, so we advise against blowing the nose strongly but just wipe off excess liquid from the nose gently with a clean tissue.
