This article will explore some of the top reasons for receiving Form 483s and warnings, including:
- Inadequate procedures
- Poor record-keeping
- Lack of training
- Contamination and cross-contamination
- Failure to follow written procedures
What Is a Form 483?
A Form 483 is a document issued by FDA inspectors after an inspection to communicate to the inspected facility the observations made during the inspection, which indicate possible violations of the Federal Food, Drug, and Cosmetic Act (FD&C Act) and related regulations. The purpose of a Form 483 is to notify the facility management of these observations, provide the facility with an opportunity to make necessary corrections, and to serve as a basis for further regulatory action if deemed necessary.
What Is a Warning Letter?
A warning letter is a formal communication from the FDA to a facility that has received a Form 483, indicating that the agency has determined that the violations identified during the inspection are serious enough to warrant regulatory action. The warning letter usually outlines the specific violations identified and requests the facility to take prompt corrective action to address the issues.
Common Reasons for Form 483s and Warnings
The FDA issues Form 483s and warning letters when they find violations of regulations during inspections. These violations can range from inadequate procedures, poor record-keeping, and lack of employee training to contamination and cross-contamination, and failure to follow written procedures, among others.
1. Inadequate Procedures
Inadequate procedures refer to procedures that are not adequate or appropriate to ensure compliance with FDA regulations. This can include a lack of procedures, incomplete or outdated procedures, or procedures not being followed correctly. Examples of inadequate procedures may include:
- Failure to establish and implement written procedures for quality control testing of finished products
- Lack of procedures for the control and handling of raw materials
- Inadequate procedures for the maintenance and calibration of equipment used in the manufacturing process
2. Poor Record-Keeping
Record-keeping is an essential part of ensuring compliance with FDA regulations. Poor record-keeping refers to a failure to maintain accurate, complete, and up-to-date records of manufacturing, testing, and distribution activities.
Examples of poor record-keeping may include:
- Failure to maintain records of equipment maintenance and calibration
- Incomplete or inaccurate records of manufacturing or testing activities
- Failure to retain records for the required time period
3. Lack of Employee Training
Lack of employee training refers to a failure to provide employees with adequate training on FDA regulations, policies, and procedures. This can result in employees not understanding their roles and responsibilities, leading to non-compliance with regulations. Examples of lack of employee training may include:
- Failure to provide training on the handling and storage of raw materials and finished products
- Lack of training on quality control procedures and testing methods
- Insufficient training on safety procedures and the use of equipment
4. Contamination and Cross-Contamination
Contamination and cross-contamination refer to the presence of harmful substances or microorganisms in products or manufacturing environments. This can occur due to inadequate cleaning procedures, lack of hygiene, or improper handling of raw materials or finished products. Examples of contamination and cross-contamination may include:
- Presence of bacteria or other microorganisms in finished products
- Contamination of products with cleaning agents or other chemicals
- Cross-contamination of products due to improper handling of raw materials
5. Failure to Follow Written Procedures
Following written procedures is critical to ensuring compliance with FDA regulations. Failure to follow written procedures can result in non-compliance and the production of products that do not meet FDA standards. Examples of failure to follow written procedures may include:
- Failure to follow written procedures for cleaning and sanitation of equipment and manufacturing areas
- Failure to follow written procedures for quality control testing of finished products
- Failure to follow written procedures for handling and storage of raw materials
Trends in FDA 483s
According to a 2019 report on “FDA 483 Observations and Warning Letters” by U.S. law firm Crowell & Moring, the top four most common observations for drugs have remained identical from 2016–2018:
1. | Quality control procedures not in writing, fully followed |
2. | Scientifically sound laboratory controls not established |
3. | Investigations of discrepancies, failure to adequately review |
4. | Absence of written procedures for production and process controls |
While the top two most common observations for devices have remained identical from 2016-2018:
1. | Lack of or inadequate procedures (CAPAs) |
2. | Lack of inadequate complaint procedures |
While not consistently ranked in the same spot, “Lack of Written MDR Procedures” and “Purchasing Controls, Lack of or Inadequate Procedures to Ensure That All Purchased Product Conforms to Specifications” have made the top five each year from 2016-2018.
Trends in Warning Letters
“Current Good Manufacturing Practices” (CGMP) was consistently the subject of the greatest number of warning letters during 2016-2018.
In categories most relevant to drugs and devices, the top CGMP violations included:
- CGMP/Finished Pharmaceuticals/Adulterated
- CGMP/QSR/Medical Devices/Adulterated
- CGMP/Dietary Supplement/Adulterated/Misbranded
- CGMP/Active Pharmaceutical Ingredient (API)/Adulterated
Consequences of Receiving Form 483s and Warnings
Receiving a Form 483 or warning from the FDA can have serious consequences for a company. The potential consequences may include delays in the approval of new products, suspension or revocation of licenses, legal action, and damage to reputation.
- Delays in the approval of new products—The FDA may withhold approval of a new drug or medical device until the company can demonstrate that it has addressed the issues raised in the Form 483 or warning. This delay can result in lost revenue and market share.
- Suspension or revocation of licenses—If the FDA determines that a company has not taken adequate steps to address the issues raised in the Form 483 or warning, it may suspend or revoke the company’s licenses to manufacture or distribute products.
- Legal action—The FDA may take legal action against a company if it determines that the company has violated FDA regulations. This can result in fines, penalties, and other legal consequences.
- Damage to a company’s reputation—Negative publicity surrounding FDA inspections and violations can erode consumer confidence in a company’s products and lead to a decline in sales.
It is important for companies to understand the most common reasons for receiving Form 483s and warnings to ensure they are compliant with FDA regulations and avoid potential regulatory action. By doing so, companies can avoid the consequences associated with receiving Form 483s and warnings and ensure the safety and efficacy of their products.
Several companies have suffered consequences due to Form 483s and warnings. For example, in 2019, the FDA issued warning letters to five companies who produce products labeled as homeopathic for significant violations of current good manufacturing practice (CGMP) regulations, leading to product recall and damage to reputation.
In 2021 a medical device company received an FDA warning following a facility inspection. The company said the warning letter “focuses on the inadequacy of specific medical device quality system requirements at the Northridge facility in the areas of risk assessment, corrective and preventive action, complaint handling, device recalls, and reporting of adverse events.” The company’s stock price dropped by almost 9% following the announcement, as the company faced scrutiny from investors and regulatory agencies.
How to Avoid Receiving Form 483s and Warnings
Receiving a Form 483 or warning from the FDA can have serious consequences for a company. However, there are steps that companies can take to avoid receiving these citations.
One tip for avoiding Form 483s and warnings is to conduct regular self-audits. Companies should regularly review their operations and procedures to identify potential areas of non-compliance with FDA regulations. This can help companies address issues before they become serious problems and demonstrate to the FDA that they take compliance seriously.
Ensuring that procedures are up-to-date and followed is another key step in avoiding Form 483s and warnings. Companies should regularly review their procedures to ensure they comply with FDA regulations and reflect best practices in the industry. Employees should be trained in all relevant FDA regulations, as well as in the company’s procedures for complying with these regulations and that they are followed consistently. This training should be ongoing and should be updated as regulations and procedures change.
Maintaining accurate and complete records is also critical for avoiding Form 483s and warnings. Companies should have systems in place to ensure that records are accurate, complete, and up to date. This includes records related to manufacturing, quality control, validation, and distribution.
When dealing with data, you want to know when the record was created and who created it. If it was modified, who modified it, when they modified it, and why they modified it.
