FDA Medical Device Labeling Requirements: Are You Complying?

Medical device labeling requirements are a key part of getting your device to market.

It’s important that we are on the same page with what “labeling” encompasses.  When we say “labeling,” there’s a common misconception that we’re just talking about the label on your device. 

In fact, the term labeling covers ALL types of labels associated with your device, including the box your device comes in and the instructions for use (IFU).

Here in the US, the FDA provides extensive guidelines around labeling, including general requirements and special sub-categories for different types of devices. You are required to know and understand what applies to your device.

Here’s what you need to consider when looking at your own labeling for compliance:

What are the FDA requirements for medical device labeling?

Labeling requirements in the United States that pertain to medical devices are found in the following Parts of FDA Title 21 of the Code of Federal Regulations (CFR):

• General Device Labeling - 21 CFR Part 801

• Use of Symbols - 21 CFR Part 801.15

• In Vitro Diagnostic Products - 21 CFR Part 809

• Investigational Device Exemptions - 21 CFR Part 812

• Unique Device Identification - 21CFR Part 830

• Good Manufacturing Practices - 21 CFR Part 820

• General Electronic Products - 21 CFR Part 1010

Remember, it’s also important to know how the FDA defines labeling. The following definition can be found on the Device Labeling page of FDA’s website.

It’s also noteworthy that they have said “some if not all” advertising counts as labeling.

General device labeling

Before embarking on labeling your device, you should first define the risk classification of the device and the intended uses. This will guide which specific parts of the regulations you need to comply with.

You also need to establish and maintain a procedure to control labeling activities, making sure to include  the following five areas:

1. Labeling integrity - the label should remain affixed to the device and should be legible.

2. Labeling inspection - is the labeling accurate?

3. Labeling storage - you need a system that ensures the correct label gets applied.

4. Labeling operations - manufacturers should control the labeling process

5. Control number - this is used to demonstrate traceability

Subpart A of CFR Title 21 covers general device labeling requirements. There is a very clear requirement that labeling must clearly identify the manufacturer of the device, including their name and place of business. 

If the device is manufactured for or distributed by another company, this must be shown on the label with a designation such as “manufactured for” or “distributed by.”

Use of symbols

Section 801.15 covers the use of symbols in medical device labeling. FDA issued its “final rule” on the use of symbols in 2016, in a document that can be read here. In this final ruling, the FDA states that it is:

Prior to this, FDA had generally required explanatory text with all symbols used on labeling, specifically:

Under the final rule, symbols established in a standard developed by a standards development organization (SDO) may be used in medical device labeling without adjacent explanatory text as long as: 

(1) The standard is recognized by FDA under its authority under section 514(c) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 360d(c)) and the symbol is used according to the specifications for use of the symbol set forth in FDA's section 514(c) recognition, or alternatively, 

(2) if the symbol is not included in a standard recognized by FDA under section 514(c) or the symbol is in a standard recognized by FDA but is not used according to the specifications for use of the symbol set out in the FDA section 514(c) recognition, the device manufacturer otherwise determines that the symbol is likely to be read and understood by the ordinary individual under customary conditions of purchase and use in compliance with section 502(c) of the FD&C Act (21 U.S.C. 352(c)) and uses the symbol according to the specifications for use of the symbol set forth in the SDO-developed standard.

Manufacturers must also include a glossary of symbols, either on paper or electronically. Labeling must clearly tell users where to find that glossary.

In vitro diagnostic products

According to the In Vitro Diagnostic Device Labeling Requirements from FDA,

In vitro diagnostic products (IVD's) are those reagents, instruments, and systems intended for use in the diagnosis of a disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. Such products are intended for use in the collection, preparation, and examination of specimens taken from the human body.

21 CFR Part 809 covers in vitro diagnostic products. Subpart B of the FDA regulation covers the labeling of those devices. 

This is quite an extensive section, with requirements for everything from appropriate storage instructions, warnings, and a summary explanation of the test and methodology.

Investigational device exemptions (IDE)

Investigational device exemptions exist to encourage the safe development and discovery of devices intended for human use while maintaining “optimum freedom” for scientific investigators to pursue this knowledge. 

In other words, IDE permits you to lawfully ship a device that would otherwise require a PMA or compliance with a performance standard for the purposes of testing the device on humans.

Part 812.5 deals with the labeling of investigational device exemptions. Among other requirements, the label must state: "CAUTION - Investigational device. Limited by Federal (or the United States) law to investigational use."

Unique device identification (UDI)

The UDI is a system established by the FDA to adequately identify medical devices sold in the United States, from manufacturing, through distribution to patient use. The UDI rule requires device manufacturers to:

1. Include a unique device identifier (UDI) on device labels and packages, except where the rule provides for an exception or alternative.

• If a device is intended for more than one use and intended to be reprocessed before each use, the device labeler must also mark the UDI directly on the device.

2. Submit device information to the Global Unique Device Identification Database (GUDID).

You can find UDI requirements in Part 830.

Medical device labeling good manufacturing practices

Good manufacturing practices include all of those outlined under the FDA 21 CFR Part 820 - Quality System Regulation. Section 820.120 includes labeling requirements, which outline the five areas we shared at the beginning of this section (labeling integrity, labeling inspection, etc.)

The point of 820.120 is to have good, reliable procedures to control and monitor labeling. These should be included in your documentation, stored in your QMS.

General electronic products

Performance standards for electronic products are found under Part 1010. Labeling is specifically covered in 21 CFR Part 1010.3.

Of note here is that you must specifically include information on the place, month, and year of manufacture. 

Medical device patient labeling considerations

The whole point of labeling is to be able to provide users of your device with clear information that will help them to use it safely and effectively. FDA defines “patient labeling” as “any information associated with a device targeted to the patient or lay caregiver.”

Your medical device patient labeling should inform users or caregivers of the proper use, risks, and benefits of the device. It should be in a language they can easily understand. That means avoiding excessive jargon or terms they will be unfamiliar with and doing what you can to simplify your instructions. 

Another consideration is formatting. For example, you might think about breaking information down into clearly numbered steps rather than presenting users with a wall of text. 

Patient labeling is not always necessary. If your device is only to be used by healthcare practitioners (for example, if your device is a scalpel), then there’s no sense in including patient labeling.

Simplify compliance with medical device labeling requirements

There are a lot of different moving parts to consider your device labeling. Your first job is to clearly define your risk categorization and indications for use, so that you can then identify the labeling requirements you must comply with.

Your design controls will play a big part in helping you to devise your final labeling. The best QMS software keeps design control elements updated at all times and provides full transparency of all data and activities throughout the total product lifecycle. 

All data stored in a closed-loop quality system will feed directly into your labeling activities, so your efforts are simplified and improved.
