Benzene contamination in pharmaceuticals has led to product recalls and increased scrutiny in recent years. Recently, the FDA has asked the USP to remove a few monographs from the compendium due to safety concerns related to benzene's carcinogenic properties, and the agency has issued a new guidance to help industry navigate the reformulation of such drug products.

The U.S. FDA issued 180 warning letters to drug and biologics manufacturers in fiscal year 2023 (FY23) and 94 of them were based on an on-site inspection of the company. This article provides an analysis of trends and observations from the inspection-based letters, as well as additional insight on the agency’s approach to enforcement.
