Hydromorphone is a prescription medication used to relieve moderate to severe pain. It is a potent opioid analgesic and is sometimes sold under brand names like Dilaudid. Hydromorphone works by binding to specific receptors in the brain and spinal cord, which helps alleviate pain.
Due to its potency, hydromorphone is typically prescribed when other less potent pain relievers have not provided adequate relief. It is available in various forms, including tablets, capsules, and liquid solutions.
