21 CFR PARTS 210 AND 211 AND OTC MONOGRAPH COMPLIANCE SUPPORT FOR DRUG MANUFACTURERS

Clear, Guided OTC cGMP Compliance

cGMP Consulting provides engineering, validation and consulting to over-the-counter (OTC) drug manufacturers, packers and brands to help them meet FDA cGMP requirements under 21 CFR Parts 210 and 211. OTC drugs are held to the same cGMP standards as prescription drugs and the CARES Act of 2020 introduced significant changes to how OTC monograph drugs are regulated.

We help you build regulatory compliance into your everyday operations without adding unnecessary complexity.

  • Managing drug establishment registration and product listing requirements
  • Understanding and meeting applicable OTC Monograph User Fee (OMUFA) obligations
  • Developing, implementing, and maintaining compliant quality systems
  • Ensuring Drug Facts labeling and product claims meet FDA requirements
  • Identifying compliance gaps and responding effectively to FDA inspection findings and enforcement actions
