Pirdal FAQ

Frequently Asked Questions

1. What is PIRDAL Nasal Spray?

PIRDAL Nasal Spray is a hypertonic polymeric solution that forms an absorbent film (nasal dressing) on the nasal mucosa (the lining inside the nose). This protective film helps to prevent contaminants from coming into contact with the nasal surface.

The osmotic properties of PIRDAL Nasal Spray attract hypotonic fluid present in the mucosal tissue, creating a flow of fluid from the interior to the surface. The mechanical mode of action makes it possible to continuously block and detach impurities and other contaminants including viruses present inside the nose and eventually omit them with nasal secretions.

2. What type of contaminants and viruses is PIRDAL Nasal Spray effective against?

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.

3. Is PIRDAL also effective on virus variants?

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.

4. How long is the protection period for each application?

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

5. How long it takes for the application to start working?

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

6. How long can I use PIRDAL Nasal Spray?

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).

7. Is PIRDAL Nasal Spray toxic or harmful to health?

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.

8. Who can use PIRDAL Nasal Spray? Are there any contraindications to using PIRDAL?

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.

Please check the composition of the product and do not use it in case of sensitivity or allergy to any ingredients found in the product’s formula.

For severe respiratory symptoms, please consult a doctor immediately.

9. When I use PIRDAL, do I still have to take other preventive measures such as wearing a face mask, social distancing, sanitizing frequently, getting vaccinated and so on?

Yes, even with the use of PIRDAL, please continue to practise other preventive measures such as wearing face masks, social distancing, sanitizing frequently, getting vaccinated and so on.

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

10. When and where should I use PIRDAL Nasal Spray to protect myself?

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.

11. Can I use PIRDAL while using other treatments?

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.

12. I had a runny nose and some irritation during the first 10 to 30 minutes when I used PIRDAL. Is this normal?

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.
