Lybalvi

This product is a combination of 2 medications olanzapine and samidorphan. It is used to treat certain mental/mood conditions (such as schizophrenia, bipolar disorder). This product can help to decrease hallucinations and help you to think more clearly and positively about yourself, feel less agitated, and take a more active part in everyday life.

Olanzapine belongs to a class of drugs called atypical antipsychotics. It works by helping to restore the balance of certain natural substances in the brain. Samidorphan belongs to a class of drugs known as opioid antagonists. It reduces the risk of weight gain caused by olanzapine.
