What is the difference between Dilaudid and oxycodone?

Dilaudid, the brand name for hydromorphone, and oxycodone are both powerful opioid pain medications but differ in their chemical structure and potency. Dilaudid is generally considered to be more potent than oxycodone, meaning smaller doses may achieve similar pain relief. Additionally, they have different formulations and onset times, with Dilaudid often providing faster relief. Both carry risks of addiction and side effects typical of opioids.
