Oxycodone is a prescription opioid pain medication. The 10mg tablet is used to treat moderate to severe pain when other pain relief methods are not sufficient. It works by binding to opioid receptors in the brain and spinal cord, reducing the perception of pain. Oxycodone affects the central nervous system (CNS). It alters the way your brain and body respond to pain, providing relief. The effects typically start within 30–60 minutes of oral administration.
