What Olanzapine-DRLA is used for
Olanzapine-DRLA belongs to a group of medicines called antipsychotics. It helps to correct chemical imbalances in the brain, which may cause mental illness.
Olanzapine-DRLA is used to treat symptoms of schizophrenia and related psychoses. Schizophrenia is a mental illness with disturbances in thinking, feelings and behaviour.
Olanzapine-DRLA alone, or in combination with lithium or valproate, is used for the short-term treatment of acute manic episodes associated with Bipolar I Disorder. Olanzapine-DRLA is also a mood stabiliser that prevents further occurrences of the disabling high and low (depressed) extremes of mood associated with Bipolar I Disorder.
Bipolar I Disorder is a mental illness with symptoms such as feeling "high", having excessive amounts of energy, needing much less sleep than usual, talking very quickly with racing ideas and sometimes severe irritability.
Your doctor may have prescribed Olanzapine-DRLA for another reason.
Ask your doctor if you have any questions about why Olanzapine-DRLA has been prescribed for you.
This medicine is available only with a doctor’s prescription.
Olanzapine-DRLA is not recommended for use in children under the age of 18 years as there is not enough information on its effects in this age group.
