Olanzapine Viatris (previously Olanzapine Mylan)

Olanzapine Viatris is used to treat adults with schizophrenia. Schizophrenia is a mental illness with symptoms such as delusions, disorganised thinking and speech, suspiciousness and hallucinations (seeing, hearing or feeling things that are not there). Olanzapine Viatris is also used to treat moderate to severe manic episodes (extremely high mood) in adults. It can also be used to prevent the recurrence (when symptoms come back) of these episodes in adults with bipolar disorder (a mental illness with alternating periods of high mood and depression) who have responded to an initial course of treatment. Olanzapine Viatris contains the active substance olanzapine and is a ‘generic medicine’. This means that Olanzapine Viatris contains the same active substance and works in the same way as a ‘reference medicine’ already authorised in the EU. The reference medicine for Olanzapine Viatris is Zyprexa.
