Acetylcysteine is used to help thin and loosen mucus in the airways due to certain lung diseases (such as emphysema, bronchitis, cystic fibrosis, pneumonia). This effect helps you to clear the mucus from your lungs so that you can breathe easier.
Acetylcysteine is a mucolytic agent, prescribed for chronic bronchopulmonary disease, cystic fibrosis and others. It works by thinning of mucus and ease its removal. It is also used in the management of paracetamol overdose.
The recommended dose for most patients is 3 to 5 mL of the 20% solution or 6 to 10 mL of the 10% solution three to four times a day.
It comes as a sterile unpreserved solution (not for injection) in vials containing a 10% (100 mg/mL) or 20% (200 mg/mL) solution of Acetylcysteine.
Caution needed for pregnant and breastfeeding women.
Do not mix Acetylcysteine with other inhaled medications unless directed by the doctor.
