Olanzapine
Summary
Olanzapine is used to treat schizophrenia, which is a mental disorder causing hallucinations and delusions, and bipolar disorder, which involves extreme mood swings.
Olanzapine works by affecting neurotransmitters, which are chemicals in the brain that influence mood and behavior, helping to balance them and reduce symptoms like hallucinations and mood swings.
The usual starting dose for adults is 5 to 10 mg once daily, with a maximum of 20 mg per day. It is taken orally, which means by mouth, and can be taken with or without food.
Common side effects include weight gain, which is an increase in body weight, drowsiness, which is feeling sleepy, and increased appetite, which is a stronger desire to eat.
Olanzapine can increase the risk of weight gain, high blood sugar, and cholesterol levels, which may lead to diabetes or heart problems. It should not be used by those allergic to it or with severe liver issues.
