Mucomyst

Generic name: Acetylcysteine
Drug class: Mucolytics

Usage of Mucomyst

Acetylcysteine is a mucolytic (medicine that destroys or dissolves mucus). It is usually given by inhalation but may be given in other ways in a hospital.

Acetylcysteine is used for certain lung conditions when increased amounts of mucus make breathing difficult. Acetylcysteine liquefies (thins) or dissolves mucus so that it may be coughed up. Sometimes the mucus may have to be removed by suction.

This medicine is available only with your doctor's prescription.

    The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:

    How to use Mucomyst

    After using acetylcysteine, try to cough up the loosened or thinned mucus. If this does not work, it may have to be suctioned out. This will prevent too much mucus from building up in the lungs. If you have any questions about this, check with your doctor.
