Oxycodone is a powerful opioid pain medication commonly prescribed to treat moderate to severe pain. It works by altering the way the brain and nervous system respond to pain. Due to its effectiveness, oxycodone is often used after surgeries or for chronic pain conditions. However, it also carries a high potential for addiction, misuse, and overdose. As a result, it is classified as a Schedule II controlled substance in many countries, meaning it should only be used under strict medical supervision.
