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.

Yellow Cards completed by patients or members of the public include personal contact information. We ask for these details so that we can get in touch if more information on the Yellow Card report is needed.

Furthermore, any details of the patient and reporter are excluded from the information that we are legally obliged to provide through the Freedom of Information act.
You can also ask someone else to send a report in about a suspected side effect if you do not wish to give us your name. We may need to contact this person for further information about the report.
The MHRA regularly publishes data about information given on the Yellow Card reports, but this never includes names or other personal details of the people who made the report.
