Olanzapine
About Olanzapine
Olanzapine is used to treat schizophrenia and manic depression (bipolar disorder). Schizophrenia is a mental condition in which the person may feel, hear or see things that are not there (hallucinations), believe things that are not true, and feel unusually suspicious or confused.
Olanzapine contains olanzapine, which helps balance brain chemicals linked to mood and behaviour. It improves thinking, stabilises mood, and reduces hallucinations (false sensations). It also helps control agitation and manic symptoms. This supports mental health and daily functioning.
Take Olanzapine as prescribed by your doctor. Common side effects include drowsiness, dizziness, restlessness, tremors/shakiness, stomach upset, dry mouth, constipation, increased appetite, fatigue, decreased libido, swelling of the hands or feet, and weight gain. If you notice any side effects that are not manageable, please consult your doctor.
Olanzapine is not recommended for treatment in patients with Dementia-Related Psychosis. If you are pregnant, planning to conceive, or a breastfeeding mother, inform your doctor before starting Olanzapine. This medicine is not recommended for children below 12 years of age.
