Additions and Modifications to the List of Drug Products That Have Been Withdrawn or Removed From the Market for Reasons of Safety or Effectiveness

The Food and Drug Administration (FDA or the Agency) is amending its regulations to revise the list of drug products that have been withdrawn or removed from the market because the drug products or components of such drug products have been found to be unsafe or not effective. Drugs appearing on this list may not be compounded under the exemptions provided by sections 503A and 503B of the Federal Food, Drug, and Cosmetic Act (the FD&C Act). Specifically, the rule adds 24 entries to this list of drug products, modifies the description of one entry on this list, and revises the list's title and introductory language. These revisions are necessary because information has come to the Agency's attention since March 8, 1999, when FDA published the original list as a final rule.
