Patient Education

Acetylcysteine Oral Inhalation


Acetylcysteine inhalation is used along with other treatments to relieve chest congestion due to thick or abnormal mucous secretions in people with lung conditions including asthma, emphysema, bronchitis and cystic fibrosis (an inborn disease that causes problems with breathing, digestion, and reproduction). Acetylcysteine is in a class of medications called mucolytic agents. It works by thinning the mucus in the air passages to make it easier to cough up the mucus and clear the airways.
