Nasaline® Frequently Asked Questions

Nasaline - Nasal Irrigation System

Can I use Nasaline if I am pregnant or breastfeeding?

Nasaline can be used during pregnancy and breastfeeding. In fact, since pregnant women should not be taking drugs for pregnancy congestion, nasal irrigation with saline solution is considered one of the best healthy natural alternatives to many over the counter and prescription drugs.

Who can use Nasaline?

Anyone 4 years old or older can use Nasaline, however, children from age 4 to age 12 should not use Nasaline without parental supervision. For children from age 4 to age 12, we suggest Nasaline Junior - a smaller unit- also to be used with parental supervision. For newborns or toddlers we recommend the Baby NäsaKleen - The Nasal Aspirator.

I've been using a Neti Pot for years, how is Nasaline different from the Neti Pot?

With Nasaline, the user actually controls the amount of pressure used, depending on the level of congestion. The patented silicon tip provides for a complete seal to the nostril, preventing any saline solution from pouring back through the same nostril for a more effective nasal rinse. Also, because you don't rely on gravity with Nasaline (as with a Neti Pot), you don't have to tilt your head awkwardly to the side, you simply stand upright, leaning slightly forward over your sink.

When making the saline solution, why is the salt-to-water ratio so important?

The saline solution has the same salt content as the human body (0.9%) - this is called a physiological (or isotonic) saline solution. Note: The proper salt/water ratio of the saline solution is VERY IMPORTANT! If too much salt is used (hypertonic), slight stinging may be felt. In some cases this may be desirable in order to shrink/reduce the swelling of the mucous membranes - but this may also dry them out if used for an extended period of time. If less than the prescribed amount of salt is used (hypotonic), a stinging sensation may also be felt and it may swell the mucous membranes. This is not desirable, as you may feel somewhat more congested than you did prior to rinsing.

Is the tip safe for contact with the skin?

The ENTIRE Nasaline applicator is latex-free and completely safe as it was specifically designed for direct contact with
the skin.

What type of water should I use?

Use distilled or sterilized water. The saline solution should be at or close to body temperature. Once mixed, use the saline solution within 24 hours or discard.

Can I use ordinary table salt?

You can use ordinary salt, but if you are planning to use Nasaline for an extended period of time, you should use salt that is non-iodized and free of preservatives or anti-caking agents – additives that have been known to produce allergic reactions. We recommend using Nasaline Salt, which is 99.99% purified and completely free of additives.

Can I use sea salt to irrigate my nasal passages?

Although typically safe for eating, sea salts are generally not clean and should not be used for nasal irrigation. Some sea salts have been known to contain algae - which could result in allergic reactions.

What dosage should I use for Nasaline?

Use two(2) full syringes twice in each nostril per rinsing session. Rinse once or twice daily or as recommended by your doctor.

How should I clean Nasaline?

Remove the tip, pull out the plunger and flush all 3 parts with warm water. The Nasaline applicator can also be cleaned with a mild dishwashing detergent. Dry all 3 parts. Once dry, keep the Nasaline unit stored with the plunger inserted into the cylinder to prevent the rubber surrounding the plunger from swelling.

Where and how should I store Nasaline?

Nasaline should be stored in a dry environment at room temperature. We recommend that you store the Nasaline applicator with the plunger inserted into the cylinder to prevent the rubber surrounding the plunger from swelling.
