Oxycodone is an opioid pain medication used to manage moderate to severe pain. It works by altering the brain's response to pain, providing relief for patients suffering from chronic conditions or post-surgical pain. Oxycodone is available in immediate-release and extended-release forms. While effective for pain control, oxycodone has a high potential for misuse, leading to dependence or addiction. Common side effects include drowsiness, nausea, and constipation.
