Applying a gentle fine mist in the nose is an excellent way to keep the nasal passages moist. NasaMist Saline Spray comes in isotonic, paediatric and hypertonic concentrations. This drug-free, non-burning saline spray helps alleviate nasal allergies, dryness, post-nasal drip and congestion from the common cold or flu. The hypertonic concentration delivers over twice the concentration of saline as Isotonic. The paediatric concentration provides a specially designed box for babies and children and the tip is same as NeliMed's standard blue box tip. Advantages of Hypertonic Solution Extra Strength* Research shows that a Hypertonic (2.7%) or more concentrated solution may help reduce congestion better than an Isotonic (0.9%) solution. This is because a more concentrated salt solution will draw more water out of the congested tissue, reduce swelling and open up the nasal passages and sinus openings to allow for better drainage. It is possible that you may experience temporary burning or stinging with the Hypertonic solution. If this persists, please use NeliMed's Isotonic spray. Nasal sprays should not be mistaken for large volume irrigation systems like Sinus Rinse Nasal Wash. Use for: nasal allergies and dryness; sinusitis, rhinitis; allergic asthma; post nasal drip; sinus pressure and nasal congestion; nasal symptoms from flu and cold; nasal irritation from occupational and house dust, fumes, animal dander, grass, pollen, environmental pollutants and smoke.
