The FDA has issued guidance for pharmaceutical companies on how to respond to unsolicited requests for off-label information about drugs and medical devices, emphasizing that all responses must be medically-based and not promote off-label use. The guidance differentiates between solicited and unsolicited requests and suggests that responses should be handled privately, ideally by medical experts. Furthermore, the document provides specific examples and cautions against social media tactics that may inadvertently solicit off-label inquiries.
