Effectiveness
How Olanzapine Affects Patients
Olanzapine is used to reduce the symptoms of schizophrenia and bipolar disorder in adults, and manic or mixed episodes in adolescents. It works by targeting certain receptors in the brain like the dopamine D2 receptor and serotonin 5HT2A receptor. This helps to reduce hallucinations, delusions, disorganized speech, disorganized thought, disorganized behavior, anhedonia, flat affect, alogia, avolition and poor attention. Olanzapine may also be used to reduce chemotherapy-induced nausea and vomiting as it has been found to be effective in providing complete response on the delay phase in 84% of individuals and control of emesis
How Olanzapine works in the body
Olanzapine works by blocking several different types of receptors in the brain. It blocks dopamine receptors, serotonin receptors, adrenergic receptors, histamine receptors, and muscarinic receptors. Out of these, blocking the dopamine receptors in the mesolimbic pathway is the most important action. Olanzapine also blocks serotonin 5HT2A receptors in the frontal cortex, which reduces the severity of side effects.
When to interrupt dosage
The encouraged dosage of Olanzapine is contingent upon the identified condition, such as Schizophrenia, Bipolar Disorder and Delirium. The measure of dosage changes, in accordance with the method of delivery (e.g. Kit - Intramuscular or Tablet, film coated - Oral) noted in the table beneath.

Olanzapine Toxicity & Overdose Risk
Taking too much olanzapine can cause drowsiness, dilated pupils, difficulty breathing, low blood pressure, involuntary muscle movement, and other anticholinergic effects. In some cases, people have experienced agitation, slurred speech, rapid heartbeat, reduced consciousness, and even death after taking more than 300 mg. If someone takes too much olanzapine, they should be given oxygen, have their stomach emptied, and be given activated charcoal with a laxative. Long-term use of olanzapine has been linked to increased risk of liver and breast tumors and fertility problems in males.

Patient Q&A Section about olanzapine
These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.
Is olanzapine a powerful drug?
"In conclusion, olanzapine may be a more efficacious drug than some other second-generation antipsychotic drugs. However, this small superiority in efficacy needs to be weighed against the risk of larger weight gain and associated metabolic problems than most other second-generation antipsychotic drugs, except clozapine."
Answered by AI
What are the side effects to olanzapine?
"If you experience any of the following symptoms, you should speak with a doctor: dizziness, feeling unsteady, difficulty keeping your balance, restlessness, unusual behavior, depression, difficulty falling asleep or staying asleep, weakness, difficulty walking, constipation."
Answered by AI
Can olanzapine be used for anxiety?
"Olanzapine is often prescribed to target multiple symptoms at once, as it is effective in treating nausea, delirium, anxiety, insomnia, and cachexia. However, it is important to note that olanzapine is a second-generation atypical antipsychotic and as such, palliative care clinicians should be aware of potential side effects."
Answered by AI
What is olanzapine is used for?
"Olanzapine can help relieve symptoms for people with mental health conditions such as schizophrenia and bipolar disorder. These symptoms can include seeing or hearing things that others do not, feeling unusually suspicious, having muddled thoughts, feeling agitated or hyperactive, being very excited or impulsive."
