The FDA’s Postmarket Evaluation of Breast Implants

The FDA is continually evaluating the postmarket safety of approved breast implants and the compliance of breast implant manufacturers with the conditions of approval for each breast implant Premarket Approval (PMA).

The FDA’s postmarket review of breast implant safety and effectiveness includes:

  • Providing input and guidance to manufacturers as they work to meet post-approval study enrollment, follow-up, and objectives.
  • Communicating study status and findings to healthcare providers and patients to help inform them of risks associated with breast implants.
  • Evaluating breast implant Medical Device Reports (MDRs), especially those related to breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) and Systemic Symptoms in Women with Breast Implants.
  • Assessing all postmarket reporting requirements associated with the approved PMA, including manufacturing changes, design changes, and annual reports. 

While the points above include overall postmarket evaluations of breast implants, the scope of this page is focused on the breast implant manufacturers’ postmarket expectations related to devices listed below.


Warning Letters Issued to Breast Implant Manufacturers

When the FDA finds that a manufacturer has significantly violated the FDA’s regulations, the FDA notifies the manufacturer. This notification may be in the form of a Warning Letter. The FDA’s webpage About Warning and Close-Out Letters provides detailed information about the issuance of Warning Letters and the process for responding and closing out the Warning Letter.
