It is not overdose that is listed as cause of death, rather is was mixed drug intoxication which is something that happens when certain drugs in combination (in this case hydrocodone and alprazolam) working together produce a toxic effect. Rate of breathing is seriously reduced and the result can be brain death. At least my favorite friend Google says so.Sleeping pill, pain pill, and an anti-anxiety pill.......
Not uncommon to have all three. I am wondering why he would take a sleeping pill and go outside.
Ambien is known to cause sleep walking...
Sounds like an overdose. Did he have back/neck issues? Was he seeing a pain management specialist? Did he have any back or neck surgery? These are all medications a lot of general practice doctors will not prescribe together. We may never know RIP Mr. Draper.
