OxyContin is a prescription medication that contains oxycodone, a powerful opioid used to manage moderate to severe pain. It is an extended-release form of oxycodone, meaning it is designed to release the medication gradually over time, providing long-lasting pain relief, often prescribed for chronic conditions like arthritis or cancer-related pain. While effective, OxyContin carries a significant risk of addiction, misuse, and overdose, especially when not used as directed.
