Suppression....: Narcotics decrease coughing by suppressing the cough at the brain level. A cough is a reflex whose purpose is to rid the lungs of potentially harmful substances like inflammatory cells, bacteria, viruses, etc. Thus, cough suppression can be harmful! see your doctor for any cough that doesn't resolve as this can be due to a serious condition. Only suppress a cough under your doctor's direction!
