Dictionary: MedWatch is FDA's Safety Information and Adverse Event Reporting Program. It is the FDA gateway for clinically important safety information and reporting serious problems with FDA-regulated products. MedWatch offers many ways to help the public stay informed. It sends safety alerts directly to subscribers as soon as they appear on the website. OEA's Office of Health and Constituent Affairs (OHCA) oversees MedWatch as well as its subscriber base to assess its growth and change over time.
