An Act specifying an electronic system to ensure that sales of certain products containing pseudoephedrine (PSE) do not exceed limits established under federal law

SD 1599 requires pharmacies and retailers to use a free electronic tracking system to monitor sales of nonprescription products containing pseudoephedrine (PSE) or ephedrine, directly affecting businesses that sell these products and customers purchasing them without a prescription. The bill enforces federal daily (3.6 grams) and monthly (9 grams) purchase limits, mandates customer ID verification and log recording at checkout, and requires electronic submission of sales data to the system starting January 1, 2026. Retailers must stop sales that exceed limits via automated alerts, with limited emergency overrides allowed for immediate safety concerns (requiring logged records). Violations carry fines up to $5,000, and the law preempts conflicting local regulations while exempting prescription-based sales.
