How Olanzapine Tablet Works

Olanzapine tablets affect the brain's chemical messengers, known as neurotransmitters. This medication blocks specific receptors in the brain, particularly dopamine and serotonin. By doing this, olanzapine impacts rebalancing these neurotransmitters, which helps improve mood and behaviour.

The drug's main action is to block dopamine receptors, which has a significant effect on reducing symptoms like hallucinations and delusions. It also works on serotonin receptors, which helps to address issues such as anhedonia and poor attention. Olanzapine's effect on other receptors, including histamine and muscarinic receptors, explains some side effects, like drowsiness and dry mouth.

It is important to note that while olanzapine significantly impacts symptoms, it may take several weeks for its full effects to become apparent.

Can I Take Olanzapine with Other Medicines?

Olanzapine can interact with many medications, supplements, and foods, such as:

• Fluvoxamine 
• Medicines for Parkinson's disease
