Rhinosinusitis, marked by nasal stuffiness, congestion, postnasal drip, blunted sense of smell and taste, and yellow-green nasal drainage is one of the commonest reasons for patients’ visit to the primary care physicians or specialists.¹ Nasal congestion, the main symptom of this disease causes great discomfort and contributes significantly to absenteeism from school or work. It has been reported to be a substantial source of morbidity, prompting an increase in healthcare costs.^1,2

Increased quantity or viscosity of sinus secretions in rhinosinusitis often overwhelm the clearing capacity of the nose, and, in turn, lead to pooled secretions and secondary bacte­rial infection. Medical management of this disease involves the use of antibiotics, decongestants, mucolytics, and corticosteroids.¹ Besides, a vast line of scientific evidence suggests the use of saline as an adjunct therapy.^1,3 It helps in promoting ciliary function and reducing edema, thereby improving drainage through sinus ostia. Also, it may aid in eliminating bacteria.¹

In content to this, a study has demonstrated significant improvement in the symptoms of rhinosinusitis with the use of a saline nasal spray.² Furthermore, researchers have stated that isotonic saline is an effective choice that has a favorable tolerability profile with no adverse clinical effects.⁴
