Opioid overdose: Opioid overdose is a condition when someone takes opioid medicine (fentanyl) more than prescribed. This can further make the individual physically dependent on a substance. In this case, instead of making enough of its own opioids, the body has begun to rely on outside opioids to maintain normal function. Symptoms may include vomiting or making gurgling noises, blue skin due to poor circulation, slow breathing, unresponsiveness, confusion, etc.
