OxyContin is an opioid (narcotic) pain medication used to relieve severe ongoing pain that is not controlled by other pain treatments. OxyContin contains oxycodone, a strong pain reliever that helps reduce pain by activating opioid receptors in the nervous system. OxyContin is an extended-release tablet that is taken every 12 hours regularly, it is not for occasional use or to be taken “as needed” for pain. As it is a long-acting opioid pain medicine it can put you at risk for overdose and death.
