As Mucolytic in pulmonary disease: Respiratory tract disorders associated with excessive viscous mucous such as- chronic bronchopulmonary disease.
As an antidote for Paracetamol overdose: Acetylcysteine, administered orally, is indicated as an antidote to prevent or lessen hepatic injury which may occur following the ingestion of a potentially hepatotoxic quantity of Paracetamol.
As for diagnostic bronchial studies: Such as bronchograms, bronchospirometry, and bronchial wedge catheterization.
2. Before you take Mucomist®
Acetylcysteine is contraindicated in those patients who are sensitive to it. Acetylcysteine should be given in caution in asthma patients.
Taking other medicines
After taking Acetylcysteine orally it increases the bioavailability of amoxicillin, but shows no effect on doxycycline and reduces the absorption of cefalexine. Acetylcysteine seems to increase the effects of nitroglycerin. Taking Acetylcysteine at the same time as activated charcoal might decrease how well it works for preventing poisoning.
