What do olanzapine tablets do?
OLANZAPINE (Zyprexa(R)) helps to treat emotional and mental problems like schizophrenia or psychosis. Olanzapine is also sometimes used for the treatment of other emotional or mental problems like manic-depressive illness, bipolar disorder, or behavioral problems that occur with dementia. Olanzapine can help you to keep in touch with reality and reduce your mental problems. It is not a cure. Generic olanzapine tablets are available.
