New VMD animal medicine reporting starts 20 May 2026

The Veterinary Medicines Directorate says a new digital service for reporting problems linked to animal medicines will go live on 20 May 2026. It will replace the older reporting tool, but the bigger story is not just about a new website. It is about how the UK keeps watch on medicine safety after products are already in use. If that sounds technical, think of it this way: once a medicine is being used in real homes, farms and vet practices, officials still need to know what happens next. A reporting system helps them spot patterns, check risks and decide whether action is needed.

From 20 May 2026, veterinary professionals, Suitably Qualified Persons, often shortened to SQPs, and animal owners will all be able to send reports directly to the VMD through the new service. That matters because it opens the door to reports from the people who actually see day-to-day changes in an animal after treatment. **What counts as an adverse event?** According to the VMD, it can be an unexpected or harmful reaction after an animal medicine is used. It can also include cases where the medicine simply does not seem to work as it should. In other words, the system is not only about side effects. It is also about medicines that appear to fail.

That is where the slightly specialist word pharmacovigilance comes in. Put simply, pharmacovigilance means keeping watch on medicines once they are being used in the real world. For animal medicines, that means collecting reports, checking them carefully and building a fuller picture of safety and performance over time. The VMD says every report matters, even ones that may seem small. One report on its own may not prove very much. But many reports together can show a pattern that would otherwise be easy to miss. That can help protect animal health and welfare across the UK.

The new service is also meant to improve the quality of what gets reported. The VMD says the form will include extra guidance to help people submit fuller, clearer information from the start. That matters because a good report is easier to assess than a vague one. The service will also feed into existing pharmacovigilance processes, which should make safety oversight more efficient and more complete. The first version will be released as a beta, so users can share feedback and the system can be improved after launch. **What this means:** the VMD is treating the new tool as something that can be refined, not a finished product that never changes.

If you are wondering what happens before 20 May 2026, the current routes still stay open. You can report an adverse event to the company responsible for the medicine, and that option will remain available even after the VMD’s own service goes live. There is an important legal point here. If you report a problem to the company, it must pass that report to the VMD within 30 days. So even when a report does not go straight to the regulator, it is still meant to reach the people overseeing medicine safety.

For approved animal medicines, the most immediate step may be the simplest one: tell your vet, or use the contact details in the leaflet that came with the medicine. If the leaflet is missing, the VMD advises looking for the company responsible for the product, sometimes called the marketing authorisation holder. A different route applies if an animal was given a human medicine or a medicine not approved for use in animals. In those cases, the VMD says you should contact it directly. The current method is to email adverse.events@vmd.gov.uk and ask for a form.

This may sound like a narrow policy update, but it says something bigger about public safety. Medicines are not judged only in a lab or at the point of approval. They are also judged by what happens later, in ordinary use, when vets, SQPs and owners notice something that does not seem right. For readers, the takeaway is simple. If an animal has an unexpected reaction, or a medicine seems not to work, reporting it is not making a fuss. It is part of how the system learns. The VMD’s new service, due on 20 May 2026, is meant to make that process easier, clearer and more useful for everyone involved.
