You inhale this medicine through your mouth using a nebulizer to thin mucus so you can cough it up. It does not cause cravings or a withdrawal syndrome.

Follow your prescribed schedule and clean your nebulizer after each use.
Acetylcysteine and dependence: what to know
Common questions
Is Acetylcysteine Oral Inhalation addictive?
No, acetylcysteine oral inhalation is not addictive and does not cause cravings or withdrawal. You breathe it in through a nebulizer to thin thick mucus and make it easier to cough up. If mucus builds up again after you stop, that can reflect your underlying lung condition, not addiction. Ask your prescribing clinician before changing your treatment, especially if you feel you need more frequent doses. Use only the prescribed amount. Contact your clinician immediately for new wheezing or chest tightness; call 911 for severe trouble breathing.
