Hi, my brother has been diagnosed with paranoid schizophrenia. He has not been taking any medicines for the past one and half years. He got married 3 months ago and since a week his symptoms have relapsed. He is non responsive, emotionless, has no clue of what or where he is and keeps laughing to himself in frequent intervals. A psychiatrist prescribed him rezidone - ls twice a day, nitaz - 10 mg Once a day and was given an injection of spenzo Depot 40 5 days back. But the symptoms have not reduced at all and he continues to be the same without any changes. Are there any chances he will recover and how many days does it take to show Improvements. Kindly request you to respond to me on top priority. Thanks.
