Uses

Quick Answer

N-Acetylcysteine (NAC) Sachet (Mucolator/ACC) is used to thin and loosen thick mucus in productive cough, COPD, Chronic Bronchitis, and Bronchiectasis. In hospital settings, IV high-dose NAC is the antidote for paracetamol poisoning. It belongs to the Mucolytic class. OTC for mucolytic use; hospital Rx for antidote use.

Primary Uses at a Glance

Productive Cough with Thick Mucus

NAC contains a free sulfhydryl (thiol) group that breaks the disulfide bonds in the glycoprotein chains of mucus. This chemical action reduces mucus viscosity (thickness) and makes it easier to clear. Drinking plenty of water (hydration) further enhances this effect.

As per pack instructions / as prescribed. Dissolve sachet in water, take after meals. Drink plenty of fluids.

COPD and Chronic Bronchitis Mucus Clearance

In COPD and chronic bronchitis, thick sticky mucus becomes lodged in the airways. NAC with long-term use can also reduce exacerbation frequency and improve mucus clearance. Use under doctor supervision — 600mg daily dose is common in these conditions.

As prescribed by your doctor. Standard dose for COPD: 600mg once daily (sachet) or as directed.

Cystic Fibrosis / Bronchiectasis

In cystic fibrosis and bronchiectasis, mucus is especially thick. NAC is used as adjunct therapy — alongside physiotherapy and hydration. Doctor supervision is necessary in these chronic conditions.

As prescribed by your doctor in combination with physiotherapy and hydration.
