Olanzapine, sold under the brand name Zyprexa among others, is a medication used to treat schizophrenia and bipolar disorder. It is also used in the management of acute manic or mixed episodes associated with bipolar I disorder and for the short-term treatment of bipolar depression.
Olanzapine is one of the atypical antipsychotics, and has a different mechanism of action than the typical antipsychotics. It is an antagonist at multiple neurotransmitter receptors, including the dopamine D2, serotonin 5-HT2A, and muscarinic acetylcholine M1 receptors.
Olanzapine is generally well-tolerated, but it can cause a number of side effects, including drowsiness, weight gain, and blurred vision. In some cases, it can also cause more serious side effects, such as akathisia, tardive dyskinesia, and seizures.

Blocks dopamine, serotonin, and muscarinic receptors.
Olanzapine is an atypical antipsychotic medication, which means that it works differently than typical antipsychotics. Typical antipsychotics block dopamine receptors in the brain, which can help to reduce symptoms of schizophrenia and bipolar disorder. However, they can also cause a number of side effects, such as movement disorders and tardive dyskinesia.
Olanzapine, on the other hand, blocks not only dopamine receptors, but also serotonin and muscarinic receptors. This broader blockade of neurotransmitter receptors is thought to be responsible for olanzapine's effectiveness in treating schizophrenia and bipolar disorder, as well as its lower risk of side effects.
Dopamine is a neurotransmitter that is involved in reward, motivation, and movement. Serotonin is a neurotransmitter that is involved in mood, sleep, and appetite. Muscarinic receptors are a type of acetylcholine receptor that are involved in a variety of bodily functions, including heart rate, blood pressure, and salivation.
By blocking these three neurotransmitter receptors, olanzapine can help to reduce the symptoms of schizophrenia and bipolar disorder. It can also help to improve mood, sleep, and appetite.
Overall, olanzapine's unique mechanism of action makes it a safe and effective medication for the treatment of schizophrenia and bipolar disorder.

- Tardive dyskinesia (involuntary muscle movements)
- Seizures
- Neuroleptic malignant syndrome (a rare but life-threatening condition that can cause fever, muscle rigidity, and altered consciousness)
The risk of these serious side effects is low, but it is important to be aware of them. If you experience any of these side effects, you should talk to your doctor immediately.
Overall, olanzapine is a safe and effective medication for the treatment of schizophrenia and bipolar disorder. The risk of side effects is low, and the benefits of treatment usually outweigh the risks.

This side effect usually goes away within a few weeks of starting treatment. However, if you are still feeling drowsy after a few weeks, talk to your doctor.

They may be able to help you manage your weight.

Serious side effects: akathisia, tardive dyskinesia.
Akathisia is a movement disorder that can cause restlessness and an inability to sit still. It is a common side effect of antipsychotic medications, including olanzapine. Akathisia can be very uncomfortable and can make it difficult to function normally.
Tardive dyskinesia is a movement disorder that can cause involuntary muscle movements, such as grimacing, lip smacking, and tongue thrusting. It is a rare but serious side effect of antipsychotic medications, including olanzapine. Tardive dyskinesia can be permanent and can significantly impair a person's quality of life.
The risk of developing akathisia or tardive dyskinesia is low, but it is important to be aware of these potential side effects. If you experience any involuntary muscle movements or restlessness while taking olanzapine, talk to your doctor immediately.
There are a few things you can do to reduce your risk of developing akathisia or tardive dyskinesia while taking olanzapine:
