Medical liaisons (MLs) play a crucial role in managing product controversies by facilitating communication between key opinion leaders (KOLs) and headquarters, ensuring accurate data dissemination to enhance trust in the company and its products. They prioritize responsiveness and compassion in customer communications, emphasizing corporate responsibility and ensuring that information flows efficiently to address concerns. By leveraging their relationships and expertise, MLs can mitigate misinformation and reinforce the integrity of drug utilization and patient safety.
