For hygiene and humidification of the nasal mucosa: head straight, introduce the tip into the nostril. Spray 1 to 2 times in each nostril. Let the excess solution run off then blow your nose.
For deeper cleansing of the nasal fossae: head tilted to the side, introduce the tip into the upper nostril. Administer 1 prolonged spray of 2 to 3 seconds. Let the excess solution run out through the other nostril then blow your nose.
2 to 6 sprays per day. After each use, clean the nozzle thoroughly with hot water and wipe dry.
