Generic Drugs - Specific Labeling Resources

For Industry

Who Is the Audience for This Website?

FDA’s generic drug-specific labeling resources are primarily directed to industry staff who develop generic drug labeling. For more information about:

Generic Drug Labeling

Generic drug labeling [labeling under an abbreviated new drug application (ANDA)] must be the “same as” the last approved reference listed drug (RLD) labeling except for permissible differences (e.g., manufacturer/packer/distributor information, package size, inactive ingredients, omission of information protected by patent or exclusivity, differences due to an approved suitability petition). 

Updating Generic Drug Labeling

ANDA holders are expected to promptly update their generic drug labeling (ANDA labeling) after FDA has approved changes to the associated RLD labeling.  Prompt revision, submission to the FDA, and implementation of revised ANDA labeling are important to ensure that the generic drug continues to be as safe and effective as the corresponding RLD.

ANDA holders should routinely review the last approved RLD labeling on Drugs@FDA to ensure that their ANDA labeling meets the “same as” requirements. For email updates about RLD labeling supplement approvals, subscribe to CDER Drug Safety Labeling Changes. ANDA holders can also obtain the last approved RLD labeling from FDA’s Division of Freedom of Information via online request, fax (301-827-9267), or mail (FDA Division of Freedom of Information Office of the Executive Secretariat, OC 5630 Fishers Lane, Room 1035 Rockville, MD 20857).

Labeling for certain ANDAs associated with a withdrawn reference listed drug (RLD) may be updated under the MODERN Labeling Act of 2020 when updating the ANDA labeling would benefit the public health and:

  • There is new scientific evidence available pertaining to the existing conditions of use that is not reflected in the labeling
  • The approved labeling does not reflect current legal and regulatory requirements for content or format; or
  • There is a relevant accepted use in clinical practice that is not reflected in the approved labeling
