Hydrocodone is primarily used to relieve severe pain, such as that from injuries, surgeries, or chronic conditions like cancer. It belongs to a class of medications called opioids, which work by binding to opioid receptors in the brain and spinal cord, reducing the perception of pain. It is typically prescribed when other non-opioid pain medications have not provided adequate relief. However, due to its potential for addiction and misuse, hydrocodone is usually prescribed for short-term use under strict medical supervision
