Use ACC 600 (acetylcysteine) is used as a mucolytic agent to thin phlegm and facilitate its removal in respiratory diseases accompanied by the formation of viscous, difficult-to-separate sputum. Such diseases include acute and chronic bronchitis, tracheitis, laryngitis, sinusitis, pneumonia, bronchial asthma, bronchiectasis, and cystic fibrosis. Acetylcysteine can also be used as an antidote for paracetamol overdose. - How to take ACC 600 mg effervescent tablets are intended for oral administration after meals. The tablet should be dissolved in one glass of water. The prepared solution should be taken immediately after dissolution. In exceptional cases, the prepared solution may be stored for 2 hours. Additional fluid intake enhances the mucolytic effect of the drug. For acute colds, the course of treatment usually lasts 5-7 days. For chronic bronchitis and cystic fibrosis, the drug can be used for a longer period to achieve a preventive effect. - Contraindications The drug is contraindicated in case of hypersensitivity to acetylcysteine or other components of the drug, peptic ulcer of the stomach and duodenum in the acute phase, during breastfeeding, and in children under 2 years of age (except when used as an antidote).
