FDA Issues Warning Letters Highlighting Quality Oversight Deficiencies

The U.S. FDA continues to emphasize the critical role of Quality Oversight in ensuring pharmaceutical product safety and efficacy. Recently, several Warning Letters were issued to companies in China, India, and Malaysia, citing significant deficiencies in their Quality Units (QU).

The Chinese company lacked an effective QU responsible for change control and periodic production reviews. The Indian firm’s QU failed to maintain data integrity, citing poor documentation and uncontrolled labeling. The Malaysian company’s QU did not provide adequate oversight of OTC drug manufacturing, including insufficient training and product review processes.

The FDA views these QU failures as systemic quality management weaknesses, not isolated incidents. It stresses that the Quality Unit must hold authority, act independently, and perform active, ongoing oversight—not merely fulfill paperwork requirements—to ensure compliance and product quality.
