What is USP?
  • United States Pharmacopeia
  • An independent, scientific organization that develops and disseminates public quality standards for medicines and other articles
  • USP standards are recognized in law and play a prominent role in federal state compliance and enforcement activities
Which drugs are required to adhere to USP standards?
  • Any drug that is recognized in the USP–NF must adhere to USP standards for identity, strength, quality, purity, packaging, and labeling or risk being deemed adulterated or misbranded under state and/or federal pharmacy laws
  • These provisions do not differentiate between branded and compounded medications
What are USP Chapters 795 and 797?
  • Updated guidelines specifying new default beyond-use dates (BUDs) of compounded products
  • USP 795 addresses non-sterile products while USP 797 addresses sterile products
What date do these chapters become official?
  • November 1, 2023
What is changing?
  • Water containing products, with activity factor greater than 0.6, will have shorter dating (BUD)
  • The quantity of compounded medication prescribed will likely need to be decreased and more refills added
  • There will be a reduced offering of flavors in accordance with these chapters
  • Liquids will not have one default BUD since there are many different types (preserved, non-preserved, oil based, water based, etc.)

Is Covetrus Personalized Care Pharmacies USP compliant?
  • Covetrus is compliant with USP standards
  • Environmental and personnel monitoring occurs at our facilities
  • We are compliant with USP 795, 797, and 800 standards that have come about in the past couple of years
Does USP impact all Covetrus Personalized Care Pharmacies?
  • USP is only applied to 503A pharmacies
  • Our 503B outsourcing facility, Atlas Pharmaceuticals, is not impacted as it is regulated by cGMP standards
What are we doing to prepare for these changes and ensure continuity of care for your patients?
  • Evaluation and testing to extend beyond use dating (BUD)
  • For sterile compounds, we have an in-house lab so we will not have to send our products out for sterility testing, which expedites the process and allows more time for the end-user to use the product before BUD
  • Expansion of our 503B catalog
  • Smaller batch sizes made more frequently
  • Prescriptions with smaller quantities and more frequent refills
  • Utilizing bracket testing to cover more ranges of affected products
  • Our Covetrus Prescription Management Platform allows veterinarians to easily update patient prescriptions to smaller order quantities when needed. Patients can also be set up on auto ship to receive those smaller quantities more frequently
