Primary Issue
Multiple claims assert indications/mechanism (psychosis, schizophrenia, dopamine receptor blocking, anxiety relief) that are not supported by the provided FDA label excerpts and conflict with the provided indication (severe nausea and vomiting in adults).
Suggested Improvement
Restrict claims to the provided label indication (control of severe nausea and vomiting in adults) and only state adverse effects and warnings that are explicitly present in the provided label text. Avoid asserting psychosis/schizophrenia/anxiety indications or dopamine receptor blocking as the mechanism unless supported by the provided prescribing information.
