1 Hydromorphone is a minor metabolite of morphine and may be excreted in urine at concentrations up to 2.5% of the morphine concentration. 2  Consequently, the detection of minor amounts of hydromorphone in urine containing high concentrations of codeine should not be interpreted as evidence of hydromorphone use.
Dilaudid is the band name for hydromorphone and is a derivative of morphine. Dilaudid is an opioid analgesic and is used for pain relief. As a comparison, hydromorphone is approximately 2-8 times more potent than morphine and is often sought as a substitute for heroin by narcotics addicts.
