Use distilled water or boil fresh clean tap water, then cool to body temperature. The water temperature should be at (or close to) body temperature and feel comfortable to the touch. Mix one-half teaspoon of salt into one cup of water; stir to dissolve the salt. (This saline solution has the same salt content as the human body - 0.9%.) Extract the saline solution completely into the syringe.
Stand or sit slightly bent over a bathroom sink, washbasin, or bathtub. Put the silicone tip against the nose so that it completely seals the nostril. Slowly push the saline solution up into the nostril. Breathe normally (or say aaah…) through the mouth and refrain from swallowing.
When the saline solution reaches the back of the nasal cavity, the palate closes automatically by reflex. The saline solution fills the nasal cavity and proceeds to pour out of the other nostril as it brings along unwanted mucous and crusty secretions. (Occasionally, some of the saline solution can trickle down the throat; this is not harmful.) A proper flushing should take anywhere from 3-7 seconds per nostril depending on level of congestion, narrowness of ones nasal passages or personal preference. Repeat the process for other nostril.
Use a tissue to gently blow out any remaining solution in the nose. Some of the saline solution can remain in the nose and trickle out a few hours later. Tilting your head forward and turning side to side immediately after flushing can prevent this. If you are severely congested, the saline solution can reach the sinus channels and can occasionally drip out of the eyes. This is not harmful and can be prevented by flushing more slowly.
Use one or two full syringes for each nostril in the morning and evening or at any time as necessary.
To Clean the Irrigator:
Pull out the piston from the syringe and flush both parts thoroughly with hot water and let it air-dry. Nasaline can also be cleaned with a mild dishwashing detergent, but it should not be necessary for cleaning. If piston does not easily slide back into chamber, put a drop of cooking oil on the back of piston tip.
If you feel discomfort or a light stinging feeling in your nose when you flush, you may be adding too much or too little salt.
If you are planning to use Nasaline for an extended period of time, non-iodized salt should be used to prevent any allergic reactions that may develop from the iodine or the algae frequently found in sea salts. We recommend using Nasaline Salt, which is 99.99% pure sodium chloride and does not contain any additives or preservatives.
