Hydromorphone is a prescription pain medication that is used to treat moderate to severe pain. It is an opioid, which means it works by binding to opioid receptors in the brain and spinal cord to block the transmission of pain signals. This can produce a feeling of euphoria in addition to pain relief.

Hydromorphone is available in various forms, including tablets, capsules, and liquid, and is usually taken by mouth or injection. It is commonly known by its brand name Dilaudid. Like all opioid medications, hydromorphone carries a risk of dependence and should be used with caution. It is important to follow your healthcare provider’s instructions when taking this medication.
