What is Acetadote?

OverviewTOP

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.

Proper UseTOP

Use acetylcysteine only as directed. Do not use more of it and do not use it more often than your doctor ordered. To do so may increase the chance of side effects.

If you are using this medicine at home, make sure you understand exactly how to use it. If you have any questions about this, check with your doctor.

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.
