My husband, a 66 year old Indian male diagnosed with paranoid schizophrenia and is on Nexito 5 mg 1-0-0, Pacitane 20mg 1-0-1, Sulpital 200 mg 0-0-1, larpose 1mg 0-0-1. He is also on Olmezest and Deplatt CV. He has gone thru had heart attack, by-pass surgery etc, in the past. Currently, he seems ok in the mornings but 3 pm onwards he becomes uncommunicative, staring, whispers, moves abnormally, cannot follow simple instructions etc. Why is this? When is he likely to get better?
