DHCP/DHPC

A marketing authorisation holder may send a direct healthcare professional communication (DHPC/DHCP) to healthcare professionals to inform them of important new safety information about the medicine and any actions they should take.

DHCP/DHPCs serve to inform healthcare professionals of, for example:

  • a suspension, withdrawal or revocation of a marketing authorisation for safety reasons;

  • an important change, for example, a restriction of indication, a new contraindication or a change in the recommended dose;

  • a medicine supply shortage;

  • quality problems with medicine.

FDA Guidance - Dear Health Care Provider Letters: Improving Communication of Important Safety Information

This guidance provides recommendations to industry and FDA staff on the content and format of Dear Health Care Provider (DHCP) letters. DHCP letters are correspondence ― often in the form of a mass mailing from the manufacturer or distributor of a human drug or biologic or from FDA ― intended to alert physicians and other health care providers about important new or updated information regarding a human drug or biologic (hereafter “drug” and “product” refer to both biologic and small molecule drug products). DHCP letters may also be distributed by email and are often made available on the Internet (e.g., on company Web sites or through patient advocacy groups).

This guidance provides recommendations on

(1) when to issue a DHCP letter,

(2) the types of information to include in a DHCP letter,

(3) how to organize that information so that it is communicated effectively to health care providers, and (4) formatting techniques to make the information more accessible.
