Dilaudid (hydromorphone) is a potent opioid analgesic prescribed for short-term management of severe pain, often after surgery or for certain cancer-related pain. Because hydromorphone carries significant risks — including respiratory depression, dependence, and overdose — it is tightly regulated and only available with a valid prescription from a licensed clinician. Patients should never attempt to obtain Dilaudid from unregulated websites or sellers; doing so risks counterfeit or contaminated product and serious harm.
