Hydromorphone belongs to the group of medicines called narcotic analgesics, which are medicines used to relieve pain. Dilaudid® is used to relieve pain in patients who require a narcotic pain medication. Dilaudid-HP® is used to relieve moderate-to-severe pain in patients who are opioid-tolerant and who require higher doses of opioid medicine.

Hydromorphone acts on the central nervous system (CNS) to relieve pain. Some of the side effects are also caused by actions in the CNS. When hydromorphone is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
