Answer

N -acetylcysteine aerosols commonly are administered in an effort to promote clearance of tenacious secretions. However, their efficacy has not been documented. In addition, N -acetylcysteine may cause acute bronchoconstriction. Some clinicians recommend its use be limited to direct instillation at the time of fiberoptic bronchoscopy.
