There may be a slightly increased risk of serious, possibly fatal side effects (such as stroke, heart failure, fast/irregular heartbeat, pneumonia) when this product is used by older adults with dementia. This product is not approved for the treatment of dementia-related behavior problems. Discuss the risks and benefits of this product, as well as other effective and possibly safer treatments for dementia-related behavior problems, with the doctor.

This combination medication is used to treat certain mental/mood disorders (such as schizophrenia, bipolar disorder). 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.
