Hydromorphone is an opioid pain medication. An opioid is sometimes called a narcotic.
Hydromorphone is used to treat moderate to severe pain.
The extended-release form of this medicine is for around-the-clock treatment of moderate to severe pain. This form of hydromorphone is not for use on an as-needed basis for pain.
Hydromorphone may also be used for purposes not listed in this medication guide.
You should not take hydromorphone if you have severe breathing problems, or a blockage in your stomach or intestines.
Hydromorphone can slow or stop your breathing, and may be habit-forming. Use only your prescribed dose, and swallow an extended-release pill whole to avoid a potentially fatal dose. Never share hydromorphone with another person.
