An isotonic solution contains a concentration of salt similar to your body’s natural fluids. Isotonic solutions are most commonly used for regular maintenance of clean, healthy sinuses – a soothing wash to remove excess mucus, dust, and allergens – and for helping address such things as post-nasal drip.A hypertonic solution contains a higher concentration of salt than your body’s fluids. Hypertonic solutions are used to draw out moisture and help reduce swelling post-surgery or with severe allergies. A hypertonic solution will generally be recommended by a physician or other healthcare professional. It can be slightly irritating until you are accustomed to it.

For an isotonic solution, use one (1) Ayr Saline Nasal Rinse packet.

For a hypertonic solution, use three (3) Ayr Saline Nasal Rinse packets.
