FDA has released for comment a draft guidance document entitled, “Draft Guidance for Industry and Food and Drug Administration Staff on Dear Health Care Provider Letters: Improving Communication of Important Safety Information.” The document addresses Dear Health Care Providers Letters (DHCP), which are mass mailings or electronic communications from a drug or biologic manufacturer to communicate important new information. The guidance provides recommendations on when to use a DHCP letter, the types of information to include in a DHCP letter, how to organize that information so that it is communicated effectively to health care practitioners, and formatting techniques to make the information more accessible. Comments will be accepted until January 11, 2011.
