Adverse drug reactions

You can report a suspected adverse drug reaction (ADR) or a side effect from a medicine or vaccine using our Yellow Card reporting site. Anybody from the United Kingdom can report this way.


Go to the Yellow Card reporting site

The Yellow Card Scheme is run by the MHRA and the Commission on Human Medicines (CHM), and is used to collect information from both health professionals and the general public on suspected side effects or ADRs to a medicine. Its continued success depends on the willingness of people to report suspected ADRs.

We collect Yellow Card reports from anyone from the UK on both licensed and unlicensed medicines including:

  • prescription medicines
  • vaccines
  • over-the-counter (OTC) medicines
  • herbal remedies
  • swine flu antiviral medicines (Tamiflu or Relenza)
  • swine flu vaccines (Pandemrix, made by GSK or Celvapan, made by Baxter).
