Reporting Serious Problems to FDA


MedWatch Form 3500B English









MedWatch is the Food and Drug Administration's (FDA) program for reporting serious reactions, product quality problems, therapeutic inequivalence/failure, and product use errors with human medical products, including drugs, biologic products, medical devices, dietary supplements, infant formula, and cosmetics.

If you think you or someone in your family has experienced a serious reaction to a medical product, you are encouraged to take the reporting form to your doctor. Your health care provider can provide clinical information based on your medical record that can help FDA evaluate your report.

However, we understand that for a variety of reasons, you may not wish to have the form filled out by your health care provider, or your health care provider may choose not to complete the form. Your health care provider is NOT required to report to the FDA. In these situations, you may complete the Online Reporting Form yourself.

Voluntary Reporting by Consumers, Patients and Health Professionals

In order to keep effective medical products available on the market, the FDA relies on the voluntary reporting of these events. FDA uses these data to maintain our safety surveillance of these products. Your report may be the critical action that prompts a modification in use or design of the product, improves its safety profile and leads to increased patient safety.
