The Yellow Card scheme is a way of helping the Medicines and Healthcare products Regulatory Agency (MHRA) collect information about the side effects of different drugs.
They do this so that they can:
make sure drug manufacturers list side effects accurately. For example, if lots of people report a side effect, they might need to reassess how common it is, or add a new warning to the Patient Information Leaflet (PIL); if enough people report a very serious side effect, the drug may be taken off the market
help other people decide whether to take the drug in future by giving more accurate information
If you experience side effects after taking a particular medication, you can report them online through the Yellow Card website, or on a yellow report card which you can get from your pharmacist. Alternatively you can ask a health professional to do this for you.
It's completely voluntary, so you don't have to do this if you don't want to.
