Nervous system

One study has suggested that the respiratory depression caused by hydrocodone may be of benefit in the treatment of dyspnea related to chronic obstructive pulmonary disease and restrictive lung disease. However, the potential for the precipitation of respiratory insufficiency makes such use of hydrocodone hazardous and such use should be undertaken, if at all, only with extreme caution.
