Dilaudid is the brand name for the opioid medication hydromorphone. It is a potent pain reliever typically used for the treatment of severe pain, often in healthcare settings like hospitals. Hydromorphone, when prescribed, is usually given in controlled settings due to its strength and potential for misuse and addiction. As with other opioids, it's crucial to use Dilaudid only under the guidance of a healthcare professional and follow their instructions to minimize the risks associated with opioid medications.
