Use of a saline nasal spray is among the simplest ways to get rid of mucus in the nose. These sprays can remove mucus and allergens from the sinuses and nose, which should lessen the discomfort caused by phlegm. Remember that saline sprays will create a runny nose right after use, which can be annoying to deal with, especially for people who are sick with the flu or a cold.

It is advised to use sodium chloride-only spray. When using a saline nasal spray, it is important to treat both the phlegm and the underlying cause of the phlegm because sodium chloride has been shown to provide a number of health advantages for respiratory disorders. It is strongly advised that people only use distilled or sterile water to irrigate their noses.
