MedWatch Form 3500A (MedWatch 3500A)

FDA Form 3500A (MedWatch) is the mandatory adverse event reporting form used to report serious adverse events to the FDA. Under MoCRA, the responsible person for a cosmetic product must submit Form 3500A to the FDA within 15 business days of receiving the initial report of a serious adverse event.

A "serious adverse event" under MoCRA is defined as an adverse health experience that results in death, a life-threatening experience, inpatient hospitalization, a persistent or significant disability or incapacity, a congenital anomaly or birth defect, an infection, or significant disfigurement (including serious or persistent rashes, second- or third-degree burns, significant hair loss, or persistent or significant alteration of appearance).

The form requires detailed information about the patient (demographics, medical history), the adverse event (description, outcome, dates), the suspect product (name, manufacturer, ingredients), and the reporter (name, contact information, professional qualification). The responsible person must also submit any follow-up information received within one year of the initial report.

Form 3500A can be submitted electronically through the FDA Safety Reporting Portal or by mail. Companies must maintain records of all adverse event reports (serious and non-serious) for six years and make them available to FDA upon request during inspections.
