Dilaudid 2 MG works well as an analgesic or pain-reliever and also as a cough suppressant. Dilaudid’s main ingredient, hydrocodone belongs to the Schedule II class of controlled substances, all of which carry a high risk for abuse and addiction. According to the U. S. National Library of Medicine, different formulations of the drug may produce short-term or long-term effects depending on any one drug’s intended purpose. ​Dilaudid, one of the more powerful opiate-based drugs, produces pain-relieving effects comparable to that of morphine. Someone affected by moderate to severe pain symptoms, such as chronic back or injury-related pain may well be prescribed Dilaudid as a treatment. Dilaudid 2 MG derives from hydrocodone, an opiate belonging to the Schedule II class of controlled substances. According to the Journal of Drug & Alcohol Dependence, hydrocodone is the most frequently prescribed opiate in the United States with estimated 130 million prescriptions dispensed in 2006 alone.
