Hydrocodone is a medication that belongs to a class of drugs called opioids. It is primarily used to relieve moderate to severe pain. Similar to codeine, hydrocodone works by binding to opioid receptors in the brain, spinal cord, and other parts of the body to reduce pain perception.

Hydrocodone is typically prescribed in combination with other medications, such as acetaminophen, to enhance its pain-relieving effects. It is available in various forms, including tablets, capsules, and syrups.
