Oxycodone is a powerful opioid pain medication prescribed to treat moderate to severe pain. It is part of the narcotic analgesic family and works by altering how the brain and nervous system respond to pain. Oxycodone is commonly found under brand names such as OxyContin, Percocet (with acetaminophen), and Roxicodone. Doctors typically prescribe oxycodone to patients suffering from chronic pain (like cancer pain or post-surgical pain) when other pain relievers are insufficient. Due to its strength, oxycodone is classified as a Schedule II controlled substance in the United States under the Controlled Substances Act, indicating a high potential for abuse and addiction.
