Indicated for: viscous bronchial secretions; paracetamol overdose
Substance: acetylcysteine (mucolytic)
ATC: R05CB01 (Respiratory system | Expectorants, excl. combinations with cough suppressants | Mucolytics)
Acetylcysteine is a medication primarily used as a mucolytic to thin and loosen thick, viscous mucus in the airways, making it easier to expel. It is indicated for respiratory conditions such as chronic bronchitis, bronchiectasis, cystic fibrosis, or pneumonia.
Additionally, acetylcysteine is used as an antidote in cases of paracetamol (acetaminophen) overdose, as it helps restore glutathione levels in the liver, protecting liver cells from damage.
The medication can be administered orally, intravenously, or via inhalation, depending on the indication. Common side effects include nausea, vomiting, diarrhea, or respiratory tract irritation. In rare cases, it may cause severe allergic reactions, such as anaphylactic shock.
Acetylcysteine is an effective and safe medication when used as directed by a healthcare provider. Patients should adhere to the prescribed dosage and inform their doctor of any adverse reactions.
