Yellow Card reporting changes ahead of November’s medicines-safety week
MHRA has updated Yellow Card reporting ahead of 2–8 November’s campaign. You can report a suspected medicine side effect without proving the cause.
The MHRA has outlined improvements to Yellow Card reporting ahead of MedSafetyWeek, which runs from 2 to 8 November 2026.
Its 26 October update describes NHS login integration and a progressive web app, including reporting options for defective or falsified products. These are reporting-service improvements, not an announcement of a new hazard affecting a particular medicine. [1]
You can report a suspicion
Patients and carers can report suspected medicine side effects. You do not need to prove that the medicine caused the problem before submitting a report. Dates, treatment details and other medicines being taken can help the MHRA assess it. [1]
Use the official Yellow Card reporting site.
Reporting and getting help are different
Yellow Card collects safety information; it does not provide medical advice. If you are worried about your health, contact your doctor or pharmacist, or NHS 111. Reporting should not delay getting the help you need. [2]

SHIFT’s take
The useful habit is to tell the responsible clinician what happened and report a suspected side effect, rather than assuming somebody else has already done it.
