From Warning to Action: Implementing DPYD Testing Following the FDA-Approved Capecitabine Label Update

January 25, 2026 Dr. Michael Lee – Health Editor Health

Here’s a breakdown of the key takeaways from the provided text, focusing on the role of pharmacists in preemptive DPYD testing in oncology:

1. Pharmacists are Key to Implementation:

* Overcoming Barriers: Pharmacists are uniquely positioned to address barriers to DPYD testing by building the business case (demonstrating cost savings from preventing toxicity), working with IT to create effective EMR systems, and educating prescribers.
* Workflow Design & Expertise: Leading the design of clear workflows and providing accessible expertise are crucial for prosperous implementation.

2. Impact on workflow:

* Minimal Delay: Preemptive testing adds a small step initially, but generally doesn’t considerably delay treatment initiation if ordered early in the treatment planning process.
* EMR Integration: Pharmacists verify orders using EMR decision support tools that automatically flag patients needing dose adjustments based on DPYD phenotype.
* Improved Patient Counseling: Allows for proactive conversations about personalized dosing for safety, shifting the focus from reacting to toxicity to preventing it. Even patients with normal results benefit from clearer expectations.

3.pharmacist’s role in Education:

* Bridging the Gap: Pharmacists translate complex genetic data into practical clinical decisions for prescribers.
* Prescriber Support: They develop educational resources (sessions, speedy-reference tools, consult pathways) to support oncologists and advanced practice providers.
* EMR Language: Pharmacists help shape clear, actionable recommendations within the EMR.
* Patient Dialog: They explain dose adjustments as personalized safety measures, empowering patients.

4. Ochsner Health’s Experience (Practical Insights):

* Structured Governance: Ochsner established a governance process under the Pharmacy and Therapeutics committee, involving a multidisciplinary team (pharmacists, physicians, genetic counselors, informatics specialists).
* EMR Rule Creation: Pharmacists were central to translating guidelines into EMR-based rules and creating alerts.

In essence, the text highlights pharmacists as essential leaders in the successful integration of preemptive DPYD testing into oncology practice, improving patient safety and treatment outcomes.
