Dilaudid is a prescription medicine and also the brand name version of the hydromorphone. It is an immediate-release medication that immediately starts to work after entering your system. It can be habit-forming over extended use, so the United States authorities classified it as a controlled medication under schedule II of the Controlled Substances Act. If you want it, you will need a doctor’s prescription, but there are many websites from where you can order Dilaudid online without prescription.
