How Often Does the FDA Inspect Pharmaceutical Manufacturers?

The frequency of FDA inspections depends on several factors, including the product's risk level, the manufacturer's compliance history, and specific regulatory requirements. On average, the FDA aims to inspect high-risk facilities every two years. However, low-risk facilities might be inspected less frequently. The FDA uses a risk-based approach to prioritize inspections, focusing on facilities with a higher potential impact on public health. Given below is a list of factors that can trigger FDA inspections:

  • The company's past inspection history: Companies with a compliance history are typically inspected less frequently than those with prior violations.
  • The type of product being manufactured: Drugs classified as high-risk due to their complexity or potential side effects may be inspected more often.
  • The agency's current inspection priorities: The FDA may prioritize inspections based on emerging concerns or industry-wide trends.

While there's no set schedule, a 2021 Government Accountability Office (GAO) report indicates that the FDA inspects most domestic drug manufacturing facilities at least once every two years.
