Hydrocodone is a prescription opioid medication that is commonly used to treat moderate to severe pain. It is a semi-synthetic opioid derived from codeine, and it works by binding to the same receptors in the brain that other opioids bind to, such as morphine and oxycodone.

Hydrocodone is often combined with other medications, such as acetaminophen or ibuprofen, to enhance its pain-relieving effects. It is available in various forms, including tablets, capsules, and liquid.
