Worried about your health?

Speak to your doctor, pharmacist or to call NHS 111 if you are worried about your health. If you’re deaf and want to use the phone service, you can use the NHS 111 British Sign Language service available in your country.

We are unable to provide you with medical advice.

Always read the patient information leaflet, or instructions supplied with your medicine or medical device. It lists the known side effects or problems and advises you on what to do.

The new Yellow Card reporting site

Welcome to the new and improved Yellow Card reporting site. Our interactive Drug Analysis Profiles (iDAPs) are now under 'What is being reported'.

We will be continuing to improve our new website platform with enhancements over 2022 based on user feedback to give you a better, more tailored and transparent reporting experience. Future upgrades will offer new features such as:

  • technology that helps keep you up-to-date with your report as it progresses through MHRA review process and enables you to update your reports.

  • easier access to real-time safety communications and control over alerts, allowing you to switch on and off relevant safety communications.

  • the ability to manage information about healthcare products via a product watch list.

  • visualisation of data that will allow you to view information in a more user friendly, accessible way.

  • for frequent reporters, a search functionality that will allow your previous reports to be found easily.

We welcome your feedback.

Please note that during the pandemic the MHRA asks for all Yellow Card reports to be sent electronically instead of using paper forms.
