Mrs. Conner's doctor says that she accidentally took 24 mg of hydromorphone (Dilaudid) once, that she was taking the standard therapeutic dose and then forgot she had taken a dose already and took the second pill. Which means her prescribed dose was 12 mg, which is quite a bit higher than the standard dose that would be given to someone with no tolerance to opioids, unlike Mrs. Conner who appeared to be a long time user which explains why she was taking such a large amount but it certainly isn't a "standard therapeutic dose". Hydromorphone is about four times more potent than morphine, the usual oral dose is 2-4 mg every four to six hours, 24 mg would actually be a dangerous dose for someone with no opioid tolerance to take all at once, it probably wouldn't be fatal to most people but it would certainly cause respiratory issues and severe disorientation and sedation.
