Pharmaceutical chatbots are increasingly used to answer patient drug questions, but they carry significant regulatory and compliance risks. While the FDA has issued guidance on AI in drug development and medical devices, it does not yet provide a framework for patient-facing drug Q&A. That means chatbots that discuss side effects, dosing, or interactions exist in a gray zone, and any missteps could trigger FDA enforcement.

The FTC enforces truth in advertising and consumer protection. Misleading claims, impersonating a doctor, or offering unverified information can lead to investigations. Some states, like Illinois, Nevada, Utah, and New York, are adding additional requirements such as licensed supervision or mandatory disclosures.

The OIG and DOJ are also paying attention. If a chatbot steers patients toward off-label use that affects Medicare or federal healthcare claims, it could lead to fraud investigations. The DOJ’s new healthcare fraud task force has already targeted AI misuse in healthcare.

Studies show chatbots provide inaccurate drug information 5–13% of the time, often with confidence, and sometimes at a reading level too high for many patients. These errors can misinform or even harm users, and regulators focus on outcomes, not intent.

Best practices include disclosing that the chatbot is not medical advice, avoiding personalized dosing recommendations, auditing responses, implementing escalation paths to live healthcare professionals, and ensuring privacy and HIPAA compliance. With proper oversight, tools like Ceres can help document disclosures and escalation pathways, keeping innovation safe and compliant.
