AI Statement
Dosing of esketamine nasal spray often starts with a higher initial dose followed by a lower maintenance dose administered a few times a week.
Label Reference
Contradicted by TRD Table 1 in 2.2: Weeks 1–4 administer twice per week (56 mg or 84 mg), Weeks 5–8 once weekly (56 mg or 84 mg), Week 9 and after every 2 weeks or once weekly (56 mg or 84 mg).
Important Omissions

Primary Issue
Contradicted dosing regimen description for TRD and multiple unsupported adverse effect/mechanism and cost/assistance claims.
Suggested Improvement
Remove unsupported claims (cost/assistance, dizziness/nausea/detached-from-reality, mechanistic 'thought' statements). Replace the TRD dosing description with the label’s Table 1 week-by-week frequencies and doses, and include the at-least-2-hour post-administration observation requirement.
