What are opioids?
Opioids (say: “oh-pee-oyds”) are a type of medicine often used to help relieve pain. They work by lowering the number of pain signals your body sends to your brain and changing how your brain responds to pain. Doctors most often prescribe opioids to relieve pain from toothaches and dental procedures, injuries, surgeries, and chronic conditions such as cancer. Some prescription cough medicines also contain opioids.
Opioids usually are safe when they are used correctly, but people who misuse opioids can become addicted. Misusing opioids means that you don’t follow your doctor’s instructions for how to take the medicine, or you take the drug illegally.
