There are many opiate painkillers, including morphine, methadone, oxycodone and hydrocodone. Dilaudid’s generic name is hydromorphone. It is another painkiller in the opiate class so the signs and symptoms of use are the same as other opiates. But unlike other opiates, the preferred way to abuse it is with intravenous injection. When abused orally or when snorted, the drug is not as effective as other opiates. But it will addict a person just as effectively as other opiates and when that person is addicted, it will be just as difficult to recover from Dilaudid addiction as from addiction to any other opiate.
