SinuSalt XL is a mixture of salts specially formulated for nasal irrigation. Each SinuSalt XL40 package contains 40 sachets equivalent to 40 nasal washes. The contents of each sachet must be dissolved in the water to the amount that fits into a SinuSalt bottle (250 ml). The water needs to be at body temperature (37°C). This saline based solution has similar salt concentration to the nasal mucosa (isotonic) and will neutralise the pH changes that can appear in the water. There are no added preservatives in this solution that would affect sensitive nasal mucosa. The SinuSalt salt composition includes Xylitol which has a humectant effect and anti-adherent properties against bacteria and fungi. Its slightly alkaline pH allows the mucus become fluidised and be easily expelled. Irrigation with SinuSalt XL promotes the nasal cilia movement and improves mucociliary clearance, which is the cleaning system of the upper airway.

This product is suitable for use by both children and adults.

SinuSalt Maintenance Kit includes:

  • 40 Sachets (Salts plus Xylitol)


Analysis from data collected at a recent Edinburgh and Lothians Viral Intervention Study (ELVIS) indicates that the high levels of SARS-CoV-2 virus, that are present in the upper respiratory tract of individuals infected with COVID-19, can be intervened with a neutral saline nasal irrigation.

It has been demonstrated that nasal irrigation reduces the duration of Coronavirus upper tract infection by an average of two and a half days.
