The acute form of hepatitis, generally caused by viral infection, is characterized by constitutional symptoms that are typically self-limiting. Chronic hepatitis presents similarly, but can manifest signs and symptoms specific to liver dysfunction with long-standing inflammation and damage to the organ.
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.
Similarly, hydrocodone is metabolized to hydromorphone, so that both may legitimately be found in the urine of a patient who is being prescribed hydrocodone (Vicodin, Lorcet, etc.)3,4 But again, the reverse is not true; a patient prescribed hydromorphone (Dilaudid) should not have hydrocodone in the urine.
