Clinical decision-support for the assessing pharmacist only. Logic is deterministic (same inputs → same output) and rule-based; it is not a substitute for professional judgment. Drug names, doses, quantities, and safety rules must be verified by the accountable pharmacist against O.Reg 256/24 Schedule 4, current OCP standards, and product monographs before any prescription is issued. The interaction/contraindication engine checks a fixed, finite rule set and is not exhaustive — complete interaction and renal/hepatic assessment remains the pharmacist's responsibility. No patient identifiers are entered or stored. Dry Eye, Mild Headache, and Nasal Congestion are authorized effective July 1, 2026 per O.Reg 133/26.
