Opened saline solution is generally not usable after 24 hours; prolonged storage may lead to bacterial contamination of the solution.

Physiological seawater nasal sprays play an important supportive role in treating various nasal and sinus conditions. By spraying physiological seawater into the nose, purulent or mucopurulent secretions associated with inflammatory diseases of the nasal cavity or sinuses can be washed away, helping restore normal nasal airflow.

After cleansing the nasal cavity with physiological seawater, the ciliary movement function of the nasal mucosa is restored, which further promotes the removal of nasal secretions through natural ciliary action. For allergic rhinitis, especially in patients with hay fever, physiological seawater nasal spray helps prevent symptom flare-ups by rinsing away inhaled allergens adhered to the nasal mucosa.

In cases of nosebleeds caused by dry nasal mucosa, physiological seawater nasal spray can help moisturize the nasal lining. The specific method of using physiological seawater should be followed under a doctor's guidance.
