It was not the argument about Zyprexa... it was why administer HALDOL, BENADRYL, and ZYPREXA all at the same time??? whats the point of a cocktail like that?
They add the benadryl as a sedative and also, as an anti-seizure addition -so the AP's don't bind to the wrong receptors (the H1's) and you end up seizing.
The accepted practice guidelines are either the IM cocktail OR restraints but never both. The IM cocktail is usually an AP, a benzo and benadryl. (or cogentin). It's kinda unusual to give 2 AP's (anti-psychotic), that was given in your case.
They either snow you or restrain you. Even so, restraints are extremely uncommon, even in hospitals. It's a really archaic practice.
Unforuntaely, the doctors only sign off on this stuff and many patients do end getting seizures because the staff thinks that "whatver" medications are a good idea - meanwhile, they don't have a clue. I know of more than one person who has been affected by medication changes made by staff (HS graduates), and ended up with contra-indicated meds, ended up having seizures, etc etc.
It sucks.
