I have recently learnt about the demerits of Oleanz RT 20, which is being given to one of my relationship, who is under treatment for last 9-10 months after having diagnosed for Schizophrenia. Now, I seek your kind advice on the following lines; 01. Will the treatment continue life long? 02. Could the dozes be gradually reduced e.g.from 20 mg to 15 to 10 to 5 & then stopped. 03. Can a person fully recover from his past ailment of Schizophrenia? 04. Are there any alternative for Oleanz, which is less harmful in the long-term?
