What Is the Recommended Dosage of Olanzapine?
The dosage of olanzapine varies depending on:

- Age
- Body weight
- Liver function
- Other medications
- Individual response

Patients should never adjust or stop their dose without consulting a licensed psychiatrist or qualified healthcare provider.
How Olanzapine Works
Olanzapine affects certain brain chemicals, mainly **dopamine** and **serotonin**. These chemicals help regulate mood, thinking, and behavior.
In conditions like schizophrenia and bipolar disorder, dopamine and serotonin signaling may be unbalanced. Olanzapine blocks specific receptors in the brain, helping reduce symptoms such as:
- Hallucinations
- Delusions
- Severe mood swings
- Agitation
Olanzapine helps manage symptoms. It does not cure mental health disorders. Long-term treatment may be required to maintain stability.
