What To Report

- Someone who has asked you to report on their behalf
You only need suspicion to report a side effect.

- call the Yellow Card reporting line on freephone 0800 731 6789 (10am to 2pm Monday-Friday only)
- using the free app – search ‘Yellow Card’.
How are Yellow Card reports used?
The UK medicines regulator, the Medicines and Healthcare products Regulatory Agency (MHRA), runs the Yellow Card Scheme. It collects reports of side effects from people taking medicines, as well as from healthcare professionals such as doctors, pharmacists and nurses also reporting suspected side effects experienced by a patient.
These reports are used to identify side effects and other safety information about medicines 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.

Submitting Report
Completing the Yellow Card Form
When using the attached form, complete as much as possible, especially all fields marked with an asterisk (*). It is helpful to have your medicines on hand while completing the form.
The form has five sections:

Provide detailed information. Include if the harm was due to a medication error (e.g., wrong drug, dose, or route).

About the Person Who Had the Suspected Side Effect
Include age, sex, height, and weight to help differentiate patients in the MHRA database and identify vulnerable groups.

About the Medicine(s) Which Might Have Caused the Side Effect
Include the batch number (found on the medicine box) and any other medicines or herbal remedies being taken.

About Your Doctor (Optional)
Provide contact details if you permit the MHRA to contact your doctor.

About You, the Reporter
Provide your name and contact details. This helps the MHRA contact you for more information if needed.
Sign and date the form before posting it in the provided envelope. If you need additional space, use a separate sheet of paper and include it with your form.
