Is hydromorphone the same as dilaudid?

Are hydromorphone and Dilaudid the same drug?

Yes. Dilaudid is a brand name for the drug hydromorphone. Hydromorphone is the generic drug name, and Dilaudid is one of its marketed brand formulations.

Why do the names sound different?

“Hydromorphone” refers to the active ingredient. “Dilaudid” is what some people call the prescription medication based on the manufacturer/brand. In practice, when a prescription says either hydromorphone or Dilaudid, it’s referring to the same opioid medication.

Are all Dilaudid products the same as each other?

They can differ by formulation (for example, immediate-release vs. extended-release), which affects dosing schedule and how quickly the medicine works. The key point is that the active drug in all Dilaudid products is hydromorphone—but the exact strength and release type can vary by product.
