Hydrocodone is a prescription medication used to relieve moderate to severe pain. It is an opioid, which means it works by binding to specific receptors in the brain to reduce the perception of pain. Hydrocodone is often combined with other pain relievers, such as acetaminophen or ibuprofen, to enhance its effectiveness. This medication is typically taken in pill form and is prescribed for conditions like post-surgical pain or chronic pain. Due to its potential for addiction and misuse, hydrocodone is classified as a controlled substance, and its use is closely monitored by healthcare providers.
