Texas State Board of Pharmacy reproposes wide-ranging sterile compounding rule revisions after extensive public comment

The Texas State Board of Pharmacy voted to repropose amendments to rule 291.133 governing sterile compounding, moving the package back out for public comment after a daylong staff presentation and extensive public comment from compounding pharmacists, trade groups and attorneys.

Board staff told members the package being reproposed implements the board—s November 5, 2024, proposals and was published in the Texas Register on Dec. 27, 2024; the Office of the Governor—s Regulatory Compliance Division issued a determinations letter on May 2, 2025, finding the amendments a reasonable exercise of the board—s authority to protect health and safety. The amendments cover definitions, personnel training and competency, environmental monitoring, categorization of compounded sterile preparations, beyond-use dating (BUD) rules, requirements for primary engineering controls and cleaning/disinfection protocols, and records and recall procedures.

Why it matters: The changes would affect how pharmacies that compound sterile products operate, how often staff must be retested, how many finished units must be sterility-tested, and the maximum batch sizes allowed. Pharmacy owners, hospital systems and large compounders said some provisions, especially those affecting BUDs and sterility/antimicrobial testing, would substantially increase costs and could curtail patient access in rural or small independent settings. Advocates for adoption said the changes align Texas rules with nationally recognized sterility standards and strengthen patient safety.

What the proposed amendments would do

- Definitions and structure: The package revises or adds definitions (e.g., anteroom, buffer room, designated person, restricted access barrier system, segregated compounding area) and replaces prior risk-level language with a category-based structure for continuing-education and competency requirements. Staff noted the rule text clarifies ISO classifications (ISO Class 5, 7 and 8) by particle counts for 0.5-micron particles per cubic meter and updates humidity and pressure requirements for primary engineering controls.

- Personnel competency and testing: The proposal specifies training in a pharmacy—s standard operating procedures (SOPs) for all people who perform or oversee compounding activities. It would require competency reevaluation at least every 12 months for all personnel categories, with media-fill (aseptic technique) testing every six months for personnel who actually compound. The draft also standardizes hand hygiene, garbing, gloved fingertip/thumb sampling and incubation requirements for those tests and applies some checks to non-compounding personnel who have direct oversight.
