FDA Compliance in Pharma Labeling: Flexo Printing’s Key Role

The U.S. Food and Drug Administration (FDA) is the main governing authority that is responsible for regulating pharmaceutical labeling to guarantee that medications are safe and used appropriately by consumers. The FDA regulations not only protect public health but also emphasize clarity and transparency in labeling. It ultimately helps consumers to make informed choices about their medications.

Short answer: FDA expects every required statement on a drug label to be prominent and conspicuous and, in general, in English (21 CFR 201.15). Flexo printing can deliver that at volume, but a fixed flexo plate cannot print a different serial number on every pack, so serialised prescription labels also need variable data printing.

The FDA has rules and regulations to make sure that medicine labels are easy to read and understand. These rules are: 

• Clarity and Visibility: Labels should be easy to read and have enough color difference to make it clear.
• Font Size: Use a font size that is large and clear enough for easy reading. For over-the-counter Drug Facts labels, 21 CFR 201.66 sets subheadings and other information at no smaller than 6-point type, and headings at the larger of 8-point type or 2 points above the text size.
• Color Contrast: Ensure enough contrast between the text and background colors to improve readability.

Essential Information:

• Medicine Name: Clearly display the name of the medication.
• Ingredients: List the active and inactive ingredients.
• Dosage Instructions: Provide clear directions on how much to take and when.
• Expiration Date: Clearly indicate when the medication expires.
• Safety Warnings: Include any necessary warnings to ensure safe use.

Importance of Compliance

Pharmaceutical companies must follow FDA labeling rules or else. Not following them can lead to big trouble. One of the biggest risks is legal issues. The FDA can fine you, recall your products, or stop you from selling certain medications. In some cases, patients might file lawsuits and those legal battles can cause financial penalties that impact your bottom line.

Beyond legal issues, patient safety is at risk when labeling guidelines are ignored. Confusing or incomplete labels can confuse patients on how to take their medications and put them at risk of health problems or side effects. Clear labels help patients use their medications safely and correctly.

And when a company ignores these rules people will lose faith in them. Once faith is broken it is hard to get it back. Also, it can hurt sales and damage relationships with other companies. Following FDA rules isn’t just about being compliant; it is about showing the company cares about health and is willing to earn and keep people’s trust.

Flexo Printing Technology

Flexographic Label Printing Technology is a widely used printing method, especially for packaging and labels. It uses flexible relief plates to transfer ink onto various materials, such as paper, plastic, and film. 

Flexographic printing is very fast. This makes it great for large production. It can print on many types of materials, such as bottles, pouches, and cartons. Once everything is set up, it is also cost-effective, producing many labels at a low cost per unit. Flexo printing provides high-quality results with sharp and bright images.

It meets the strict regulations for printing critical information like dosage instructions and warnings. The inks used in flexo printing are durable and resistant to moisture and chemicals so labels will withstand different environments. And you can have high customization so brands can design labels that look great and meet all the safety requirements.

Adapting to Regulatory Changes

FDA regulations are always changing to enhance safety and keep up with advancements in the pharmaceutical industry. Flexographic printing (flexo printing) can easily handle these changes for a few important reasons:

• Quick Changes: Flexo printing makes it easy to change labels quickly. If new rules come out that require updates, like safety warnings or dosage info, the flexible plates used in flexo printing can be changed easily. This allows companies to print new labels fast without long delays.
• Small Print Runs: Flexo printing can print smaller amounts of labels, which is helpful when companies need to update labels for specific products. This reduces waste and makes sure labels are always up-to-date.
• High Quality: Flexo printing creates clear and sharp labels that meet strict government rules. This is important for following rules about font size and other details.
• Custom Designs: As rules change, labels might need new designs. Flexo printing allows for custom designs, so companies can add new logos or graphics.

Serialisation and the US Product Identifier

For prescription drugs sold in the US, the Drug Supply Chain Security Act adds a data requirement on top of the printed text. FDA's guidance on product identifiers explains that the identifier combines the NDC with a unique serial number of up to 20 characters, plus the lot number and expiration date, in both human-readable and machine-readable form. On each package the machine-readable part must be a 2D data matrix barcode.

Because every pack needs its own serial number, this data is added through variable data printing rather than fixed flexo plates. Sai Impression offers variable data printing for QR, serial and batch codes and prints medical and pharmaceutical labels. Share your specification and we will advise on the right label build.

Challenges in Flexo Printing for Pharmaceutical Labeling

While flexographic printing offers many advantages, there are a few challenges that pharmaceutical companies may face when using it for labeling.

• Precision and Detail Requirements: Pharmaceutical labels must be highly accurate and easy to read, with precise fonts, clear colors, and sharp images for dosage instructions and safety warnings. However, achieving this level of detail can be difficult with flexo printing, especially on small labels. Adjusting the plates for fine details requires significant skill and expertise.
• Color Consistency: These labels need to have the same color every time, especially for instructions and warnings. However, small changes in the ink or how hard the machine presses can change the color slightly.
• Material adaptability: Some medicines need special packaging to keep them safe from light or moisture.  It might need extra steps or special inks, which can make it more expensive and complicated.
• Frequent Regulatory Updates: Government rules for medicine labels often change. This means labels need to be updated frequently, which requires new printing plates or setups. This adds time and cost to the printing process.

Best Practices for FDA-Compliant Flexo Printing in Pharmaceutical Labeling

Here are some actionable tips for pharmaceutical companies to keep labels FDA-compliant while using flexo printing:

• Stay Updated on Regulations: Keep up with the latest government rules for labels. Have a team check for new rules and let the printing team know right away.
• Check for Quality: Regularly check labels for clarity, color, and consistency. This can help catch mistakes early, like blurry text or fading colors.
• Focus on Small Details: Pay attention to small details like font size and color contrast, especially on small labels. Use high-quality ink and adjust the printing plates to make sure everything is clear.
• Choose the Right Materials: Pick materials that meet government rules and work well with flexo printing. Test the printing on different materials to make sure the ink sticks and the colors stay consistent.
• Invest in Training and Equipment: Train workers to use the printing machines well. Regularly maintain and upgrade the machines to keep them working properly.

Frequently Asked Questions

Do FDA rules require a particular printing method for drug labels?

The label rules covered here, such as 21 CFR 201.15 and 201.66, set requirements for content, prominence and type size rather than naming a printing process. What matters is that the printed label is accurate, legible and durable.

What is the minimum text size on an OTC Drug Facts label?

Under 21 CFR 201.66, subheadings and other information must be no smaller than 6-point type, and headings must be the larger of 8-point type or 2 points above the text size. Slightly smaller title and heading sizes (7-point, or 1 point above the text) are allowed only where the required content takes more than 60 percent of the available labelling area.

What must be on each prescription pack under the DSCSA?

A product identifier made up of the NDC, a unique serial number, the lot number and the expiration date, in human-readable form and as a 2D data matrix barcode on each package.
