My Elderly Mother Takes Atorvastatin For Pressure And Donepezil For

My elderly mother takes atorvastatin for pressure and Donepezil for memory. She started taking citalopram for depression following the deathof her husband recently she has become increasingly psychotic hearing auditory hallucinations almost constantly. I feel she should stop the anti depressant. she was treated for a a urinary tract infection recently so that seems to be a ruled out cause.
