Prohibits certain steering and marketing practices involving dispensing of prescription drugs and drug samples.

S 1158 prohibits drug manufacturers, pharmacies, wholesalers, and healthcare practitioners from using devices, kiosks, or systems to steer patients to specific pharmacies or limit their pharmacy choice when dispensing prescription drugs or samples. It requires that any transmission of patient information to a pharmacy must be voluntary or accompanied by full disclosure of the patient's right to choose their pharmacy. Violations carry civil penalties: $100,000+ for companies and $250+ for practitioners per offense, collected by local health agencies. The bill directly affects healthcare providers, drug suppliers, and pharmacy systems that use technology for drug dispensing. It aims to protect patient autonomy in pharmacy selection while preventing misuse of patient data for marketing.
