How to apply Nasaleze: In 5 steps



Step 1 – Blow your nose.

Step 2 – Remove cap and shake the bottle side to side.

Step 3 – Administer a test spray to gauge the pressure required for an ideal dose, which is a 10 to 15cm plume of powder. If you find the bottle too stiff to squeeze with one hand then use both hands (once you are used to taking Nasaleze the test spray is no longer needed).

Step 4 – Place the nozzle of the bottle just inside the nose and apply 1 to 2 sprays into each nostril. Inhale gently while squeezing but do not inhale deeply.

Step 5 – Re-apply each time you blow your nose.
