🟨 Making Yellow Card Reports 🟨

In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) operates the Yellow Card scheme for reporting issues with medicines.

They have slightly different approaches to:

β€ƒβ€ƒπŸŸ‘ Side Effects

β€ƒβ€ƒπŸŸ‘ Defective medicines

β€ƒβ€ƒπŸŸ‘ Counterfeit or fake medicines

All can be accessed by following this link:


It vitally important that we report issues. Although we might wish that we could rely on medical staff (doctors, nurses, pharmacists, etc.) to make reports, the truth is they often do not. Often no-one has told them of the issues they are having. Even if you know they have made a report, your report will add to the information. You will explain it differently and might include different details.

I do not like the culture of blaming patients which seems to be far too common. But in this case, we can only blame ourselves if we do not file reports.

If in doubt, make a report. The MHRA must expect that some reports are inappropriate and will have mechanisms in place for handling them. It isn't your responsibility to make that decision. All that can reasonably be expected is that you make reports in good faith, taking care to be as accurate as you can.

Making a report is straightforward. Depending on the issue, you might be asked to photograph the medicine (or device) and upload them. Probably a good idea to take a set of photographs before you start the report.


If you change makes and find the new one better, you might wish to report the previous make.

Retain all packaging (for example, card outer, blister packaging, Patient Information Leaflet) - even if you do not have any of the product left.

If you use some sort of daily pill dispenser, you might consider keeping any packaging for a while so it is available should you need it.


Yellow Card Mobile App: You can now receive news updates from the MHRA and report side effects to medicines via the Yellow Card app. Please download it from the Apple App Store or Google Play Store. Key features of the app include the ability to create a β€˜watch list’ of medications for which you can receive news and alerts from the MHRA. You can view numbers of Yellow Cards reported to the MHRA for medicines of interest and see previous Yellow Cards you have submitted through the app. At the moment account details are not synchronised between this website and the app, so you need to create separate accounts.


COVID-19 Issues

There is a special Covid-19 page which includes vaccines, diagnostic testing kits, a few specific medicines and several other things.

Outside the UK

There are other routes outside the UK. For example the USA's FDA has a reporting mechanism.

The European Medicines Agency (EMA) handles reports for centrally licensed products - each EU country handles its own for nationally licensed products.

Thanks helvella for this information. I agree it’s vitally important to report side effects. I have just discovered that my intercranial hypertension and other health issues are being caused by Levothyroxine. All medics have told me that its not the case or that they have never come across this before but i know this is not true because when I stopped my meds all my symptoms disappeared. But of course they are only looking at reported issues.

And here’s Government guidelines on levothyroxine stating many patients find different brands are not interchangeable

Please Yellow Card adverse reactions to changing brand


For the 5-year period between 1 January 2015 and 31 December 2019, the MHRA received 335 Yellow Cards reporting one or more of the terms β€˜product substitution issue’, β€˜condition aggravated’ or β€˜drug ineffective’ with levothyroxine. The majority of reports were received from patients rather than healthcare professionals, with 47 of the cases having a healthcare professional reporter.

We see many many members who have adverse reactions to changing brands….far more than 335 in 5 year period

Please Yellow Card any brand change issues

Please, everyone, don't be put off with thoughts such as:

β—Ύ They won't do anything.

β—Ύ I'm not taking it any more so it doesn't matter.

β—Ύ Last time I did a report, I never heard anything back.

β—Ύ It will take ages to do a report.

β—Ύ I told my doctor/pharmacist/nurse so there's no need for me to do one.

The more reports, the more likely a good outcome. For others if not for you.

Thank you. It is most important to report any side effects. We can’t rely on doctors for doing so because they usually dismiss any report! When I told my previous rheumatologist that I wanted to stop using methotrexate because I felt like I was being poisoned she was quite angry and told me this could not be the case because Methotrexate was well tolerated! Incredible!
