Nasal spray sodium chloride or sea water), isotonic (0.9% sodium chloride) and hypotonic (0.65% sodium chloride). Isotonic solutions have the same salt concentration as the human body, whereas hypertonic solutions have a higher salt content and hypotonic solutions have a lower salt content. Isotonic saline nasal sprays are commonly used in infants and children to wash out the thick mucus from the nose in case of allergic rhinitis. Hypertonic solutions may be more useful at drawing moisture from the mucous membrane and relieving nasal congestion.
