To protect public safety and maintain a high standard of quality in the pharmaceutical industry, the U.S. Food and Drug Administration (FDA) conducts investigations into companies that manufacture and package drugs. Both small start-ups and large pharmaceutical companies may be the subjects of FDA investigations. If the inspector observes conditions that seem to violate FDA regulations, they may issue a pharmaceutical warning letter. Depending on your company’s regulatory response to the letter, the FDA may close out the investigation or take more serious legal action if deemed necessary.


Though receiving an FDA warning letter is not the end of the world, your company must understand the letter, respond appropriately and take action to achieve compliance, which can pose challenges if you aren’t sure what is expected of you.


What Happens After You Receive a 483 Inspection Observation or a Pharmaceutical Warning Letter

The FDA issues several types of letters to pharmaceutical companies. Depending on the situation, you may receive a Form 483, a warning letter or a consent decree. A Form 483, which details a number of specific concerns, is issued after an investigation if an inspector sees conditions or practices they believe may violate the Food Drug and Cosmetic Act or other regulations. An FDA warning letter is issued to a company that has significantly violated FDA regulations and lays out a timeframe for corrections.


Whether you receive a form 483 or a warning letter, you are expected to develop a regulatory response to the FDA in writing. Included in your strategy will be addressing and remediating compliance issues as quickly and thoroughly as possible. Taking comprehensive action is essential to getting your company back on track.
