Hydrocodone is a potent opioid used to manage severe and persistent pain that requires an extended treatment period with a daily opioid pain medicine, when other non-opioid pain medicines do not treat your pain well enough, or you cannot tolerate them. Hydrocodone belongs to the group of medicines called opioid analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain, and stops or prevents cough. When hydrocodone is used for a long time, it may become habit-forming, causing mental or physical dependence. Hydrocodone is used to relieve severe pain. Hydrocodone is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
