Does Nasoclear saline nasal spray help relieve cough?
Nasoclear saline nasal spray may help relieve a cough only if the cough is caused by postnasal drip from a cold, allergies, or sinus congestion, as it clears nasal blockage and reduces mucus that drips into the throat, but it does not act as a direct cough suppressant and will not help if the cough is due to chest infection, asthma, or other lower airway causes, so medical evaluation is advised to determine the cause and guide proper treatment.
