Oxycodone is a prescription opioid medication primarily used to manage moderate to severe pain. Oxycodone belongs to a class of drugs known as narcotic analgesics, which work by affecting the brain and nervous system to reduce the sensation of pain. At the dosage, oxycodone is considered a high dose, often prescribed for patients who have chronic pain or pain that does not respond well to other, less potent pain relievers. It is available in various forms, including immediate-release and extended-release formulations.
