Patient Education

Hydromorphone


Hydromorphone is used to relieve pain. Hydromorphone extended-release tablets are used to relieve severe pain in people who are expected to need pain medication around the clock for a long time and who cannot be treated with other medications. Hydromorphone extended-release tablets should only be used to treat people who are tolerant (used to the effects of the medication) to opioid medications because they have taken this type of medication for at least one week and should not be used to treat mild or moderate pain, short-term pain, pain after an operation or medical or dental procedure, or pain that can be controlled by medication that is taken as needed. Hydromorphone is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
