How Do You Report Side Effects to the FDA?
Learn how to report medicine side effects to the FDA, when MedWatch is the right path, and what information helps the agency review your report.
To report side effects to the FDA, use MedWatch for suspected serious problems with human medical products such as medicines, biologics, medical devices, combination products, and some cosmetics. Get urgent medical help first for emergencies, then report the product name, what happened, when it happened, and any details that may help FDA evaluate the issue.

FAQ
Can patients report side effects directly to the FDA?
Yes. FDA says health professionals, patients, and consumers can voluntarily report suspected adverse events for human medical products through MedWatch.
Should I report a side effect if I am not sure the product caused it?
Yes, if you suspect a serious side effect or product problem. FDA uses voluntary reports to identify possible safety issues, even when a single report does not prove causation.
Is MedWatch the right place for vaccine reactions?
No. FDA points vaccine-event reports to VAERS, while MedWatch is the usual path for human medicines, medical devices, biologics, and similar medical products.
