Vistaril (R)
(hydroxyzine hydrochloride)
Intramuscular Solution
For Intramuscular use Only
....
Hydroxyzine has demonstrated its clinical effectiveness in the
chemotherapeutic aspect of the total management of neuroses and
emotional disturbances manifested by anxiety, tension,
agitation, apprehension or confusion.
....
It induces a calming effect in anxious, tense, psychoneurotic
adults and also in anxious, hyperkinetic children without
impairing mental alertness. It is not a cortical depressant but
its action may be due to a suppression of activity in certain
key regions of the subcortical area of the central nervous
system.
....
Indications: The total management of anxiety, tension and psychomotor agitation in conditions of emotional stress requires in most instances a combined approach of psychotherapy and chemotherapy. Hydroxyzine has been found to be particularly useful for this latter phase in its ability to render the disturbed patient more amenable to psychotherapy in long term treatment of the psychoneurotic and psychotic although it should not be used as the sole treatment of psychosis or of clearly demonstrated cases of depression. ....

According to what Hubbard's doctor told the coroner, and what the labs from the autopsy found, Hubbard had been injected with Vistaril and only Vistaril in a non-hospital setting. That's what you do with a psychiatrically disturbed or drug withdrawal patient.
