Welcome to the on-line reporting site for the Yellow Card Scheme

You can report suspected side effects (also known as adverse drug reactions) to a medicine, vaccine, herbal or complementary remedy by clicking "Report Side Effect" below.

The Yellow Card Scheme, run by the MHRA and the Commission on Human Medicines, is used to collect information from both health professionals and the general public on suspected side effects.

Report Side Effect

Important information about side effects

All medicines can cause side effects. Some may not yet be known so that's why it's important for people to report to the Yellow Card Scheme. Many side effects are mild, but some can be serious and even life-threatening. Others appear after taking a medicine for a long time or even after stopping a medicine.

It is important for people to report as these are used to identify side effects and other problems which might not have been known about before. If a new side effect is found, the MHRA will review the way that the medicine can be used, and the warnings that are given to people taking it to minimise risk and maximise benefit to the patient. Further information can be found under our FAQ section.

If you would like to report an adverse incident involving a medical device, an adverse blood reaction/event or a suspected counterfeit product, see reporting other problems

Please note we cannot provide medical advice. If you are worried about a symptom you think may be a side effect:

  1. Check the patient information leaflet supplied with the medicine. This lists the known side effects and advises you what to do.
  2. Talk to your doctor or pharmacist.
  3. Call the NHS
    • NHS Direct in England (see www.nhsdirect.nhs.uk for contact details)
    • NHS24 in Scotland on 0845 4 242424 (textphone 18001 08454 242424)
