Reporting Side Effects
Patient safety is our first priority.
We encourage healthcare professionals, patients and the general public to report any information about the safety, quality or performance of a Pfizer product. This includes potential adverse events, reports on certain circumstances that may increase a patient’s risk of developing an adverse event, as well as other reportable information, including product complaints and unexpected therapeutic effects.
All Pfizer employees play a critical role in meeting our legal and ethical responsibilities to collect and analyse reports and are fully trained in how to recognise and report an adverse event. We have to report all such events to the regulatory bodies, whether or not we can confirm their accuracy.
What to do if you experience side effects whilst taking a Pfizer medicine
If you are taking or prescribed a Pfizer medicine and experience any side effects, you should immediately report these to your doctor, to another healthcare professional (such as a nurse or carer) or to the company that produced your medicine.
The Medicines and Healthcare Products Regulatory Agency (MHRA) can be contacted through its Yellow Card reporting system.
