Saline washes for allergic rhinitis: sponsored

Common allergy rhinitis (hay fever) treatments and their effectiveness have been highlighted in recent news with US guidelines recommending corticosteroid nasal sprays as first line treatment for those with moderate to severe hayfever symptoms¹. However, many consumers seek relief from over-the-counter antihistamine tablets from pharmacies as a quick fix solution.

The US guidelines support recommendations from the Australasian Society of Clinical Immunology and Allergy (ASCIA) that have long recommended corticosteroid nasal sprays to help treat chronic hay fever. See ASCIA’s update on allergic rhinitis ASCIA Allergic Rhinitis Clinical UpdateAllergic Rhinitis Clinical Update.

There is also evidence to suggest using an isotonic nasal saline or sinus rinse first to clean the nose or sinuses as this can improve the effectiveness of corticosteroid nasal sprays².

More recently NPS Medicinewise recognised the benefits of saline washing in the role of hay fever symptom control and have included it within their recommendations for hayfever medicines³. So why is saline washing helpful when managing hay fever symptoms?

When allergens are breathed in, they reach the moist tissues of the nose and if one is allergic to them, then an allergic reaction follows. The tissues own chemicals, such as Histamine, produced as part of this reaction unfortunately lead to the common hay fever symptoms such as a congested nose (blocked or runny), an itchy nose, sneezing and itchy, watery eyes.

Nasal or sinus rinses can be of help because they help to wash away pollens and reduce the pollen load in the nasal tissues. Similarly this helps to dilute and remove some of the tissue chemicals that are responsible for the hay fever symptoms, thereby decreasing their severity⁴. For those with particularly sensitive or irritated noses, a preservative-free, isotonic saline may be preferable. Ask your pharmacist or healthcare practitioner for further advice on which saline is most suitable.

Australian and US guidelines recommend that you get onto a treatment plan early, weeks before hay fever season starts. Talking with a qualified health care practitioner is of great importance especially for those who suffer chronic allergy or hay fever symptoms and associated respiratory problems.
