What is the most important information I should know about hydromorphone (Dilaudid)?

Hydromorphone may be habit-forming and should be used only by the person it was prescribed for. Never share hydromorphone with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

Never take hydromorphone in larger amounts, or for longer than recommended by your doctor. Follow the directions on your prescription label. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
