Hydrocodone is a prescription opioid medication used to relieve moderate to severe pain. It is often combined with non-opioid pain relievers like acetaminophen (as in Vicodin, Norco, or Lortab) to enhance its effectiveness. Hydrocodone works by binding to opioid receptors in the brain and spinal cord, which changes how the body perceives and responds to pain. It is also available in extended-release formulations designed for patients who require continuous pain management.
