Welcome to health care magic forum,
is psychiatric disorder. what medicines, you are giving to this patient are not curative. patient has to take it life time when one is stopped and another is started. this medicine only control the condition never cure it.
as it is psychiatric disorder, homeopathy
is best option for it.
medicine can cure schizophrenia and after some time patient will be free from medication.
So consult good classical homeopath. You will surely get benefit with homeopathy.
hope that you will get my point
Have a good health
