Acetylcysteine ​​or acetylcysteine ​​is a drug used to thin mucus in several conditions, such as asthma, emphysema, bronchitis, or cystic fibrosis. In addition, this drug is also used to treat paracetamol poisoning.

Acetylcysteine ​​works by breaking down proteins in phlegm so that the phlegm becomes thinner and easier to expel when coughing. In addition, acetylcysteine ​​also has antioxidant properties that can protect the liver from damage during paracetamol poisoning.

In addition to the oral form of medication, acetylcysteine ​​to thin phlegm is also available in the form of inhalation fluid. Inhaled acetylcysteine ​​works directly to the respiratory tract and lungs, so its effects can be felt more quickly.

How to Use Acetylcysteine ​​Correctly 

To treat paracetamol poisoning, administration of oral or intravenous acetylcysteine ​​must be given in a hospital and under the supervision of a doctor. This is because paracetamol poisoning sufferers need to be closely monitored periodically.

To treat phlegmy cough, acetylcysteine ​​can be used independently. Follow the doctor’s advice and the rules for using the drug listed on the packaging label. Do not increase or decrease the dose without the doctor’s permission.

Acetylcysteine ​​should be taken with food or after meals. Take acetylcysteine ​​tablets or capsules with water. For acetylcysteine ​​granules, dissolve 1 sachet of acetylcysteine ​​granules in water according to the dosage recommended on the label. Stir the solution until evenly mixed before drinking.

For acetylcysteine ​​effervescent tablets, dissolve them in a glass of water before taking them. This medication should be taken within 2 hours of dissolving.

For acetylcysteine ​​dry syrup, fill the dry syrup bottle with water according to the instructions on the label. Always shake the bottle until the medicine is well mixed before taking acetylcysteine ​​dry syrup.

Try to take acetylcysteine ​​at the same time every day for maximum therapeutic effect. If you forget to take acetylcysteine, take it as soon as you remember. However, if it is almost time for your next dose, ignore the missed dose and do not double the next dose.

Store acetylcysteine ​​in a closed container at room temperature and away from direct sunlight. Keep the medication out of reach of children.
