My elderly (82yo) mother took compazine tonight for she felt nausea and perhaps vomitted so she took another... she also takes fentanyl patches, lidocaine patches, and a plethora of other meds. Underlying disease processes 4th stage renal disease and degenerative arthritis in neck, back and shoulders- which is the cause of pain and need of pain meds. she developed hallucinations tonight; would that be from the compazine or an interaction of it with her other meds? Thanks.
