The guidance provides an overview of FDA policy on exchanging off-label drug and medical device information. It acknowledges the importance of social media but does not provide comprehensive guidance on its use. The FDA allows scientific exchange of unapproved use information in response to unsolicited consumer requests, but off-label promotion is illegal. While recognizing the public health value, the guidance notes challenges in ensuring digital responses are not promotional and do not disseminate off-label information more broadly. Companies are advised to limit public responses to contact details and approved labeling links.
