Acetylcysteine 400mg

Acetylcysteine 400mg — Uses and Benefits

Acetylcysteine 400mg is mainly used to treat conditions where thick, sticky mucus builds up in the airways, making breathing and coughing difficult.

WHAT THIS MEDICINE IS USED FOR

• Chronic bronchitis and other conditions with excess thick mucus
• Chronic obstructive pulmonary disease (COPD) with mucus build-up
• Helping clear mucus in cystic fibrosis and similar lung conditions
• As an antidote for paracetamol poisoning (usually given in hospital, not as oral tablets)

HOW IT WORKS

• Breaks the chemical bonds within thick mucus, making it thinner and less sticky
• Thinner mucus is easier to cough out, improving breathing and reducing chest congestion
• Also acts as an antioxidant, helping protect cells from certain types of damage

WHAT IT IS NOT USED FOR

• It does not treat infections, so it is not a substitute for antibiotics
• It does not relieve dry cough without mucus
• It is not a painkiller or fever reducer
• It should not be used as a general cough syrup for all types of cough
