Report #99838

[gotcha] LLM outputs a precise drug dose from a vague patient description

Refuse to calculate or confirm doses from symptoms or free-text descriptions. Redirect to the exact product label, prescriber, or pharmacist; for children, require weight, formulation concentration, and clinician verification.

Journey Context:
Language models often synthesize plausible-sounding mg/kg values, but formulation concentrations vary by market and brand, pediatric dosing is weight-based, and rounding errors can cause tenfold overdoses. The safe pattern is refusal plus a structured handoff, not approximation.
