Hydrocodone is a widely prescribed medication used to treat pain. It is classified as an opioid analgesic, meaning it works by binding to opioid receptors in the brain and spinal cord to block pain signals. Hydrocodone is often used to manage moderate to severe pain, and is available in various forms, including tablets, capsules, and liquid.

One of the most common uses for hydrocodone is to treat acute pain, such as post-surgery or injury pain. It is also prescribed for chronic pain conditions, such as arthritis or cancer. However, due to its potential for abuse and addiction, it is only recommended for short-term use, typically no longer than a few weeks.
