VMD Tightens Control as Veterinary Medicines Directorate Releases Strict New Packaging Rules for General Sales Drugs Across the United Kingdom, Sparking Industry Debate Over Cost and Compliance Pressure

Veterinary product manufacturers and applicants in the UK have been given updated direction following new guidance released by the Veterinary Medicines Directorate (VMD).

The focus is on how medicines intended for general sales should be packaged, labelled, and sized before they can be approved for distribution under the AVM-GSL category.

The move is aimed at making sure animal owners can clearly understand what they are buying without needing professional advice at the point of purchase.

Why the Update on Packaging Matters

Medicines classified under the Authorised Veterinary Medicine – General Sales List (AVM-GSL) are unique because they can be sold directly to the public without input from a vet, pharmacist, or suitably qualified person.

That lack of professional mediation places more responsibility on packaging and product information.

According to the VMD, the details on the pack or leaflet must be clear enough to guide animal owners in choosing the correct product safely and confidently.

Who the New Guidance Targets

The updated instructions are aimed at companies and individuals applying for veterinary marketing authorisations or submitting variation requests.

This includes:

• New veterinary product applications intended for AVM-GSL status
• Existing products seeking reclassification from higher-risk categories like NFA-VPS to AVM-GSL
• Manufacturers adjusting packaging or pack sizes under an existing authorisation

The VMD also stressed that each marketing authorisation number can only carry one distribution category, meaning all pack sizes under that approval must comply with AVM-GSL requirements if applicable.

What the Guidance Actually Covers

The document lays out several key expectations for applicants.

It explains what must appear on outer packaging, including clear and accessible product information designed for non-professional users.

It also highlights the importance of simple, user-friendly language and consistent structure, so instructions are easy to follow.

If a separate leaflet is included, the same clarity standards apply.

Another key point is pack size. The VMD notes that only “typical maximum” sizes appropriate for general sales will be accepted, reinforcing the idea that AVM-GSL products should remain suitable for casual, direct-to-consumer use.

Understanding Veterinary Distribution Categories

To put the update in context, veterinary medicines in the UK are grouped based on risk and the level of professional oversight required.

These categories include:

• POM-V (Prescription Only Medicine – Veterinarian)
• POM-VPS (Veterinarian, Pharmacist, or SQP)
• NFA-VPS (Non-Food Animal – Veterinarian, Pharmacist, or SQP)
• AVM-GSL (General Sales List)

As the categories move down the list, the level of required professional involvement decreases, placing more emphasis on product clarity and safety information for end users.

Impact and Consequences

The updated guidance is expected to tighten expectations for manufacturers, especially those aiming to shift products into the general sales category.

Companies may need to redesign packaging, simplify instructions, or reduce pack sizes to meet compliance standards.

For animal owners, the change is intended to improve safety and reduce confusion at the point of purchase.

Clearer packaging should make it easier to identify correct dosages and appropriate usage without needing veterinary interpretation.

However, for industry players, the rules may also mean additional reformulation or relabelling costs, particularly for products previously positioned closer to prescription categories.

What’s Next?

With the guidance now published, applicants are expected to align new submissions with the updated standards immediately.

Existing products seeking reclassification or variations will also need to meet the clarified requirements during review.

The VMD is likely to assess future applications more strictly where packaging clarity or pack size suitability is in question, reinforcing its emphasis on safe, self-directed animal treatment for AVM-GSL products.

Summary

The Veterinary Medicines Directorate has strengthened its guidance on packaging and product presentation for veterinary medicines sold under general sales rules.

The update focuses on improving clarity for consumers, ensuring safer use of animal medicines, and setting consistent expectations for manufacturers seeking AVM-GSL approval.
