How To Get Rid Of Phlegm
Use Saline Nasal Spray

One of the easiest ways to get rid of phlegm in the nose is to use a saline nasal spray. These sprays are able to clear out both allergens and mucus from the sinuses and nose, which should make it easier to deal with the effects of phlegm. Keep in mind saline sprays will cause a runny nose in the immediate aftermath of using the spray, which can be frustrating to deal with, particularly for individuals suffering from a cold or the flu.
Spray comprised solely of sodium chloride is recommended. Sodium chloride has been known to have a variety of health benefits for respiratory conditions, which means both the phlegm and underlying cause of the phlegm should be addressed when a saline nasal spray is used. When individuals irrigate their nose, it is highly recommended that the water they use is either distilled or sterile.
Try Expectorants

Mucus is always in an individual's body and is typically a healthy component of the respiratory system designed to trap and get rid of harmful particles. When individuals become sick, however, this mucus can thicken into a heavier phlegm substance, which can be difficult to handle. In order to reduce or get of phlegm altogether, individuals should try expectorants, which are medications designed to loosen and thin phlegm to the point where they should be able to cough it up and get it out of their system. These medications work by adding some water to the mucus, effectively thinning out the mucus.
Individuals should keep in mind, though, that expectorants are not designed to treat the underlying condition or infection causing the increased phlegm, which means they'll still need to seek additional treatment. However, using expectorants should be able to help individuals sleep better at night and more effectively deal with the symptoms of their sickness during the day. This is an over-the-counter medication that usually lasts for around twelve hours per dose. There are also versions of the medication specifically designed to be used by children. Make sure to always follow the instructions on the package for the correct dosage.
