Even after the first application with the inhalant you notice a slight improvement. At least dissolves mucus and stuck by moistening are also the pain much more pleasant. My child uses the inhaler with the solution regularly in respiratory infections. It makes the whole thing a little more bearable.
The vials are individually applicable. In each vial stuck 2.5ml liquid solution. Practical and hygienic one ampoule for an application is broken. My pack delivered was 2.5 year shelf life.
I will buy again definitely.
