Reporting Adverse Events

Important Note: Patients should always ask their doctors for medical advice about adverse events.

In the United States

You may report an adverse event related to Pfizer products by calling 1-800-438-1985 (United States only). If you prefer, you may contact the US Food & Drug Administration (FDA) directly.

The FDA has established a reporting service known as MedWatch where healthcare professionals and consumers can report serious problems they suspect may be associated with the drugs and medical devices they prescribe, dispense, or use. Visit MedWatch at www.fda.gov/Safety/MedWatch or call 1-800-FDA-1088.

Outside the United States

Countries worldwide may have specific processes in place to handle reports of adverse events. To report an adverse event, ask your health care provider for more information or contact your local health authority.
