Brief Answer:
Olanzapine is right drug for these symptoms

Detailed Answer:
Hello, Welcome to Health Care Magic

I can understand your concern about your brother. His symptoms like sudden anger outbursts, suspiciousness suggest some psychotic disorder and should be evaluated properly. Abusing others, suspecting family members etc symptoms are seen commonly in bipolar disorder or psychosis. More detailed history is needed to make diagnosis.

Olanzapine is an antipsychotic drug and is right drug for these symptoms. The drug should be given regularly for control of these symptoms. Doses of 10-15 mg per day would result in control of these symptoms. Please discuss with his doctor for increase in dose of Olanzapine because in my opinion 5 mg dose would not help much.

Thanks, Hope this helps you, if you have more doubts you can ask again

Brief Answer:
The drug should be given for long time

Detailed Answer:
Hello again

Discuss about the dose of the Olanzapine I've mentioned. In usual cases the drug helps to control the symptoms with in 6-12 weeks of starting treatment. For psychosis long term treatment is needed.

Please mention what are his presenting symptoms. How they appeared, progressed? Any precipitating or aggravating factor for these symptoms? Any response to medicines? Any ideas of grandiosity in him? Whether he feel himself superior to others? Any risk taking behaviour, excessive money spending? Any complaints of hearing voices, talking to self? How is his social life?

Thanks
