Apply to change a veterinary Marketing Authorisation or Homeopathic Remedy
Source: gov.uk (2025-11-28)

Guidance for the pharmaceutical industry on how to apply to vary a veterinary Marketing Authorisation (MA) or Homeopathic Remedy.

Scope

These variation procedures apply to MAs authorised in Great Britain (GB).

They also apply to MAs that have been authorised in Northern Ireland (NI):
- via a national procedure, that is, not subject of an EU procedure such as the Mutual Recognition Procedure (MRP), Decentralised Procedure (DCP) or Centralised Application Procedure (CAP)
- via an EU procedure where the variation is dealt with on a national basis, such as change of legal entity of MA holder.
Further guidance about variation procedures for MAs authorised in NI via an EU centralised procedure can be found on the European Medicines Agency (EMA) (https://www.ema.europa.eu/en/veterinary-regulatory/post-authorisation/variations-veterinary-medicines-0) website.

Marketing Authorisation Holders

All products included in a variation application must belong to the same marketing authorisation holder (MAH).

In GB and NI, an MAH is identifiable by their unique company number, which forms the first part of a product’s Vm number, which appears on its labels, for example, 12345/5010.

Types of variation

There are two types of variation:
- Variations NOT requiring assessment (VNRAs)
- Variations requiring assessment (VRAs)
Variations not requiring assessment

VNRAs have little or no impact on the safety, quality or efficacy of a product. These changes are listed in the European Commission guidance (https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32021R0017&from=EN).

Variation requiring assessment

Any change that is not listed as a variation not requiring assessment will be considered a variation requiring assessment.

VRAs are listed in the European Commission guidance (https://www.ema.europa.eu/en/documents/regulatory-procedural-guideline/guidance-details-classification-variations-requiring-assessment-according-article-62-regulation-eu/6-veterinary-medicinal-products-documentation-be-submitted-pursuant-those-variations_en.pdf)

Not all possible variations are included in the lists of VNRAs and VRAs. If you wish to apply for a variation that is not listed, please email the VMD prior to submission,xxx@xxx.xx (mailto:xxx@xxx.xx) and include ‘variation classification request’ in the subject line.

If you wish to apply for a change that isn’t listed to an NI MA, please follow the procedure on the EMA website (https://www.hma.eu/578.html#c6815).

Some unlisted variations that have already been classified by the VMD as unforeseen variations, and are dealt with on a national basis regardless of the scope of the MA, have been given a national ‘U’ classification category. See Unforeseen Variations (#Unforeseen-variations) section below.

Variations not requiring assessment

A VNRA application may only include one change to one MA, a single variation.

However, to reduce administrative burden on you, we will accept the following VNRA change combinations in a single national application form:
- One VNRA change to multiple products, maximum of 10 products
- Multiple VNRA changes to one product, maximum of 10 changes
Multiple VNRA changes to multiple products is NOT permitted.

Combined application forms will be progressed as individual applications and may not all be approved at the same time.

VNRA cannot be grouped with VRA applications but can run concurrently. If the VNRA is dependent on the outcome of a concurrent VRA assessment, the application will be placed on hold pending the VRA approval.

You must submit your VNRA within 30 days following implementation of that change.

These notifications are checked to ensure that:
- the correct variation type and category has been selected
- no other changes have been made that haven’t been applied for
- all conditions have been fulfilled
- all relevant documentation has been provided and is accurate
You will be informed as to whether the variation is approved or rejected within 30 days of receipt. The fee applies regardless of the outcome.

Where at least one of the requirements cannot be fulfilled, the VNRA will be rejected, and you will still be charged. You will need to reapply using the correct VRA category.

For Northern Ireland MA authorised via a European procedure, most VNRA should be submitted via the Union Product Database. The following VNRA categories should be submitted via national applications, as described above:
- A.1(a) - Changes to the name, address or contact details of the Marketing Authorisation Holder
- C.10(a) - Changes to the holders representative
- C.10(c) - Inclusion of traceability stickers in or on the product carton
- C.1 (if different between RMS and CMS) Changes in the name or address or contact details of a qualified person for pharmacovigilance - QPPV
- C.5 (if different between RMS and CMS) - change in the pharmacovigilance system master file (PSMF) location
- C.6 (if different between RMS and CMS) - introduction of or changes to the summary of the PSMF
Further guidance is available from the EMA (https://www.ema.europa.eu/en/veterinary-regulatory/post-authorisation/variations/variations-guidance-under-veterinary-medicinal-products-regulation/variations-not-requiring-assessment-veterinary-medicines) on Centralised NI MA submissions.

Variations requiring assessment

A VRA is known as one of the following depending on the specified timeframe for that change.
- VRA – standard / extended
- VRA – reduced
Refer to Timetables for national applications (https://www.gov.uk/government/publications/timetables-for-national-applications-for-mas-atcs-and-vhrs) for further information. The ‘shortened’ timetable will be used for VRA – reduced and the ‘standard’ timetable will be used for VRA – standard / extended.

Extensions

Formerly known as ‘extensions’ there are some variations that fundamentally alter the terms of an MA to either create a new stand-alone MA (new-extension) or change an existing MA (variation-extension).

All variation-extensions follow a VRA – standard / extended timetable.

National new extensions (applicable to GB only) follow a complex timetable.

Parallel GB and NI submissions are not possible for applications that result in a new stand-alone MA due to differences between EU and National timetables.

Consequential changes to product literature

If a variation results in consequential changes to the Summary of Product Characteristics, labelling or package leaflet, these will be considered as part of the same variation application.

Single variation

An application including one change to one MA, that is one product.

Grouped variations

An application including either:
- several VRA changes to one MA
- one VRA change to several different MAs
- several VRA changes to several different MAs
A grouped variation will be handled using the longest timeframe associated with any change included in the application.

All changes included in a grouped application must apply to all products.

You can’t include a VNRA in a grouped variation.

You can’t include a former extension that results in a new stand-alone MA in a grouped variation. However, you can include former extensions that amend an existing MA, a variation-extension, in a grouped variation; this application will still be known as an ‘extension-led grouped variation’ for fee purposes.

It is recommended that you avoid groupings that are entirely unrelated for example, grouping of unrelated quality and safety / efficacy variations. If you do the VMD may decide to run the application on a longer timeframe and additional costs may be incurred.

Workshare variations

EU workshare procedures can be applied to MAs in NI issued following an EU procedure (DCP/MRP/EUCE) only.

It is recommended not to include MAs aligned between GB and NI as this is likely to result in MA number separation for GB and NI territories (where products were authorised pre-2021) and may result in de-alignment. Contact VMD for further guidance should you need to submit an EU workshare involving aligned MAs.

Variations to parent products

Informed consent (‘copycat’)

A parent MA holder has a responsibility to notify a copycat holder when changes have been made and should provide them with at least the categories used for the variation(s) and ideally, the application number. The copycat holder needs this information to apply for the same changes.

Changes to copycats and parents belonging to the same MAH may be included in a grouped application.

Marketing Authorisations for Parallel Import (MAPIs)

If the SPC or product literature of the UK authorised parent product is changed, you must submit a national Unforeseen Variation to align the MAPI product.

Change of legal category

The legal category may also be referred to as the distribution category.

A product may only be distributed on the marketplace in accordance with the distribution category shown on the product label. Therefore, until the change in distribution category has been implemented onto the packaging of a product it must continue to the distributed in accordance with the distribution category shown on the product label.

For further information about distribution categories see the guidance on Retail of veterinary medicines (https://www.gov.uk/guidance/retail-of-veterinary-medicines). When applying for a legal category change, select U.II.z.g) in the application form.

When applying for a change of legal category, applicants must consider relevant legislative criteria regarding classification of veterinary medicinal products. For the purposes of GB, the relevant legislative criteria are set out in Schedule 3, Part 1, Paragraph 1 of the Veterinary Medicines Regulations (2013), as amended. For the purposes of NI, these are set out in Article 34 of Regulation (EU) 2016/9.

Legal category variations will usually be considered by the Veterinary Products Committee (VPC) unless the VPC has already provided advice on the appropriate legal category of products containing the same active ingredient(s) and indicated for use in the same target species.

If you apply to make a national legal category change to a NI MA authorised via MRP / DCP, for example, POM-V to POM-VPS and it is likely that the variation will be approved, your national application will be placed on hold and you will need to submit further applications to introduce any proposed changes to the EU SPC or wording in the product literature. Once the European variation is approved, we will conclude the national legal change variation.

NI only - centralised products

A change to the legal category from prescription to non-prescription, or vice versa, will be dealt with by the EMA via a centralised variation procedure.

Unforeseen variations

A number of unforeseen variations have been identified and these are listed below. These variations are dealt with on a national basis regardless of whether the MA is nationally authorised or mutually recognised.

You should complete the application form including the relevant variation category given here, and include a clear, concise description of the variation in the present and proposed sections.

Labels will not be assessed as part of these variation categories. If there are significant changes to format or layout, you will need to submit a subsequent VRA G.I.15(z).

Administrative changes – U.I.z

Refer to MAHs, Named Distributors and Local Representatives of veterinary medicines (https://www.gov.uk/guidance/apply-to-change-marketing-authorisation-holder-distributor-or-local-representative-details) for guidance on how to make changes.

SPC or Product literature changes - U.II.z

Miscellaneous changes - U.III.z

An abbreviated resubmission of a previously refused variation (Type II or VRA – standard / extended), you must:
- confirm that at the time of refusal the VMD gave you permission to resubmit under this category, and that the application has been resubmitted within 3 months from the date the previous application was refused
- provide responses to the refusal points
- choose category U.III.z.a)
Following formal advice of the VMD, you must:
- confirm that the VMD has already assessed the relevant data and formed an opinion on these, and that the change is not required as a result of your failing to keep the Part II (quality) data in accordance with current practice, or in line with current CVMP guidelines
- if required, provide revised labels, package leaflet and SPC
- choose category U.III.z.b)
These changes will be dealt with on a standard timetable: See Timetables for national applications (https://www.gov.uk/government/publications/timetables-for-national-applications-for-mas-atcs-and-vhrs) for further information.

Alignment of MAs in GB and NI

MAs may be considered aligned if they:
- have the same MAH (legal entity)
- are the same pharmaceutical form
- have the same qualitative and quantitative composition
- are intended for the same target species with the same indications
- have the same dossier. Except for certain differences that make no impact on the scientific requirements or regulatory framework such as sites of batch release
NI MA authorised via MRP / DCP

To maintain alignment of your MAs in GB and NI, you must submit post authorisation applications to both the EU and the VMD for assessment at the same time, known as parallel submissions. Not submitting identical applications to either authority may introduce divergence and result in MA de-alignment.

If changes occur during the respective assessment by the GB and EU authorities, that either contravene UK or EU regulations or change the terms of authorisation valid in GB compared to NI, this may result in MA de-alignment.

NI MA authorised via Centralised procedure

For EU Centralised procedure biological applications, upon CVMP approval recommendation, it is critical that you provide VMD with a copy of any approved revisions/changes to the finished product tests and specifications, at release and at the end of shelf life, in order that NI IVMP batch release activities can be completed post approval.

Parallel submissions

EU (NI) applications can run in parallel with National (GB) applications where the products are aligned.

Both applications will run in accordance with the EU timeline.

You must submit your applications to the EU and UK within 2 working days of each other and ensure you cross-reference them in your applications.

As the procedure progresses you must submit updated GB SPC and QRD documents every time you submit updated EU SPC and QRD documents. This is to include the final version of key documents upon completion of the decision period.

Parallel submissions are not possible for:
- VNRA – in order to maintain GB and NI MA alignment, if your aligned MA GB application affects EU shared documents, your GB application will be placed on hold awaiting the equivalent UPD submission/approval and subsequently processed simultaneously. Please cross refer UPD and GB application references to avoid any unnecessary delays.
- applications involving former extensions that result in a new stand-alone MA due to the different timescales and procedures used on a national basis and in the EU
- EU Workshare procedures
- EU Centralised procedures
For non-parallel applications, if you wish to increase the likelihood of a shared GB and NI label being possible, we require you to submit EU procedural information, Lists of Questions, your responses, assessment reports, as part of your GB national procedure company responses, that will enable your GB assessors to try and align GB QRD text with the EU procedure decisions.

NI MA authorised nationally

For aligned MAs authorised on a national basis in GB and NI or where the variation is dealt with on a national basis regardless of the scope of the NI MA, you are encouraged to include all products in the same single application (for VNRAs) or grouped application (for VRAs). Not doing so may introduce divergence and result in MA de-alignment.

MA Separation (Pre 2021 authorisation)

If a pre-2021 UK-wide MA, that retains a Vm 4000 authorisation number, becomes de-aligned during a variation procedure or results in the need to separate EU shared MA documentation (e.g. QRD or SPC). You will be issued with a new authorisation number for GB (Vm 5000) and NI (Vm 3000), requiring changes to product literature and labelling.

We will notify you where applications result in splitting of pre-2021 MA numbers as early in the procedure as possible. You have 12 months from the date of the notification to implement the new MA numbers on labelling components but should use them for all subsequent regulatory matters with immediate effect.

If you choose to separate a Vm 4000 MA number and there are no other changes to the dossier, a VRA U.I.z.c can be submitted.

How to submit your application

Refer to Submission of applications to an animal medicines (https://www.gov.uk/guidance/submission-of-an-application-for-an-animal-medicine-licence) for guidance.

You must be registered to use the Veterinary Medicines Digital Service (VMDS) (https://www.gov.uk/guidance/veterinary-medicines-digital-service).

If your application affects the SPC and/or QRD text, no other applications that also affect these documents should be ongoing on the product when the variation is submitted. You must ensure that you time submission of applications, so that they do not clash.

Application forms

Application forms are available through VMDS.

For national applications involving extensions, you need to use the VRA application form if you are amending an existing MA (variation-extension), but the new MA electronic application form if you are creating a new stand-alone MA (new-extension).

An application form to vary a product authorised in NI via an EU procedure (http://esubmission.ema.europa.eu/eaf/index.html), not to be dealt with on a national basis, is available.

Validation

Variations requiring assessment (VRA) will be validated (https://www.gov.uk/guidance/validation-of-applications-for-veterinary-medicines) upon receipt to check that everything has been provided, so that assessment can begin.

It is up to you to identify and submit all the necessary information in support of your application. If the application is incomplete, we may not be able to progress it. For variations involving more than one change and / or more than one product, the application will only pass validation once all aspects are considered acceptable. We will contact you if further information is needed.

Fees

Once an application has passed validation or upon receipt for applications that do not have a validation period, you will be sent an invoice for the fee by email so you must provide a valid email address in your application.
- Refer to Fees relating to Marketing Authorisations: GB (https://www.gov.uk/government/publications/fees-applied-to-veterinary-medicine-authorisation-applications-in-gb/fees-relating-to-marketing-authorisations-ma)
- Refer to Fees relating to Marketing Authorisations: NI (https://www.gov.uk/government/publications/fees-applied-to-veterinary-medicine-authorisation-applications-in-northern-ireland/variations-to-marketing-authorisations-mas-or-veterinary-homeopathic-remedies-vhrs)
Assessment timescales

Once the application has passed validation, or upon receipt for an application that does not have a validation period, it will go into the assessment phase. Refer to Timetables for national applications (https://www.gov.uk/government/publications/timetables-for-national-applications-for-mas-atcs-and-vhrs).

Applications being run in parallel with an EU procedure, a parallel submission, will run in accordance with the EU timeframe. We will send our questions and our decision whether to approve or refuse around the same time as the corresponding EU procedure.

The timescales for mutual recognitions applications (https://www.hma.eu/156.html) are in the relevant Best Practice Guides, available on the CMDv website. Timescales for Centralised applications will be provided by the EMA.

If during the assessment phase we need further information from you, our timescales will be suspended until the information is received.

Assessment outcome

If the assessment outcome is to approve an application, we will send you the authorisation documentation using the secure messaging service available on the VMDS. Documentation will be sent to the application contact unless otherwise stated in the ‘other information’ field in the application form.

It is possible that not all changes included in a group application will have the same outcome and can be a mixture of approved and refused. You will be notified of the outcome of each change along with the authorisation documentation.
