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 which may increase a patient’s risk of encountering 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.

If you are taking or are prescribed a Pfizer medicine and experience any side effects, you should immediately report these to your doctor or to another healthcare professional (such as a nurse or a carer).

If you have any concerns about a specific Pfizer medication (bearing the Pfizer logo) you can contact Pfizer Medical Information in the United Kingdom on
