Which medication is a powerful narcotic that can be reversed with Narcan?

Dilaudid, which is the brand name for hydromorphone, is indeed a powerful narcotic that can be reversed with Narcan, also known as naloxone. Naloxone is an opioid antagonist that works by binding to the same receptors in the brain that opioids do, effectively reversing the effects of opioids in cases of overdose. As a potent opioid analgesic, hydromorphone can lead to significant respiratory depression when taken in high doses or when misused, which is a critical concern in terms of opioid overdose. In such situations, naloxone can quickly restore normal respiration and is a crucial intervention in emergency settings.

While the other medications listed are also narcotics and can have serious effects, they are generally less potent than hydromorphone. Oxycodone, hydrocodone, and codeine can all be reversed by naloxone, but the specific identification of hydromorphone as a powerful narcotic with a high potential for overdose effects and the established efficacy of naloxone in those scenarios makes it the most appropriate answer to this question.
