Inhaled acetylcysteine ​​is a medicine to thin mucus in several conditions, such as cystic fibrosis, bronchitis, emphysema, pneumonia, or tuberculosis (TB). This medicine should only be used based on a doctor’s recommendation.

Inhaled acetylcysteine ​​works directly on the lungs. This drug works faster when compared to oral acetylcysteine. When inhaled, inhaled acetylcysteine ​​can thin mucus and stimulate coughing. That way, accumulated mucus can come out immediately and breathing becomes easier.

Unlike oral acetylcysteine, this drug cannot be used to treat paracetamol poisoning.
