Atypical Antipsychotic Medications: Olanzapine

Who can be prescribed olanzapine?
Olanzapine (brand name, Zyprexa) may be prescribed for people with schizophrenia and related pyschoses.

How long before it starts to work?
People being treated with olanzapine may see some benefits within six weeks of starting to take it. If it is not helping, then the doctor may consider adjusting the dose or replacing it with a different antipsychotic medication.

What are the possible side-effects?
Some people taking olanzapine may experience blurred vision, weight gain, sleepiness, increased appetite, dizziness, low blood pressure, dry mouth and constipation.

What can be done about these side-effects?
Some of these side-effects, such as sleepiness, may decrease over time, while others may be helped by the doctor reducing the dose prescribed. Problems with weight gain can be helped by a careful diet and regular exercise.

How do I find out more?
It is important that you discuss any concerns you have with your doctor or case manager. The SANE Guide to Treatments also contains more detailed information on medications and other forms of treatment for people seriously affected by mental illness.
