ACC 600 Long Effervescent Tablets are intended to help manage respiratory disorders by putting out mucus and reducing airway congestion. Acetylcysteine, the key ingredient, works as a mucolytic, breaking down thick mucus in illnesses such as bronchitis, cystic fibrosis, and chronic obstructive pulmonary disease (COPD). These tablets dissolve in water for convenient administration and provide a 600 mg dosage each tablet.
