Dilaudid, the brand name for hydromorphone, is a potent opioid analgesic used for severe pain management, often in hospital or closely monitored outpatient settings. It works by strongly activating opioid receptors in the central nervous system, significantly reducing pain perception. Due to its potency, hydromorphone carries serious risks including respiratory depression, sedation, tolerance, dependence, and overdose. Common side effects include nausea, constipation, dizziness, itching, and drowsiness. Dilaudid is a Schedule II controlled substance and requires strict medical oversight. Safe treatment depends on precise dosing, careful monitoring, and individualized care planning. It is typically used when other pain medications are ineffective and as part of a comprehensive pain management program focused on patient safety and long-term wellness.
