Harnessing Pharmacogenomic Testing for Personalized Psychiatry
Introduction
As a Black therapist and psychiatric mental health nurse practitioner serving Illinois, Minnesota and Florida, I’ve seen how conventional medication management doesn’t always work for everyone. Because each person’s genetic makeup affects how they metabolize medications, a one‑size‑fits‑all approach can lead to trial‑and‑error prescribing and frustrating side effects. Pharmacogenomic (PGx) testing—a type of genetic test that analyzes how your genes affect your response to medications—offers a more personalized path. This post explores how PGx testing works, its benefits and when it might be right for you.
What is pharmacogenomic testing?
Pharmacogenomics studies how genetic variations influence a person’s response to medications. A simple cheek swab or saliva sample can reveal variations in genes that control how drugs are absorbed, metabolized and cleared from your body. In psychiatry, PGx testing focuses on genes affecting antidepressants, mood stabilizers, stimulants and antipsychotics. When combined with your clinical history and symptoms, the results help clinicians choose medications and dosages better suited to your body.
Benefits of PGx testing in psychiatric care
Faster relief with fewer side effects – PGx testing may reduce the trial‑and‑error cycle. Knowing your metabolizer status (e.g., fast, normal or slow) helps avoid medications that cause unpleasant side effects or provide little benefit.
Improved medication adherence – Patients are more likely to take medication consistently when it works well. Personalized prescribing fosters trust and encourages adherence.
Lower healthcare costs – Avoiding ineffective medications and unnecessary hospitalizations can reduce long‑term costs. Although the test has an upfront expense, insurance may cover all or part of it.
Inclusive care – Genetic variations differ among ethnic groups. As a Black mental health provider, I recognize that PGx testing can address disparities in treatment outcomes for communities of color.
Who should consider PGx testing?
PGx testing may be appropriate if you:
Have tried multiple medications without satisfactory relief or experienced severe side effects.
Take several medications that could interact (polypharmacy).
Have a family history of drug sensitivities or adverse reactions.
Want to minimize the use of trial‑and‑error prescribing at the start of treatment.
It’s essential to note that PGx testing complements—not replaces—clinical judgment. Results must be interpreted by a licensed provider who understands both genetics and psychiatry.
Getting tested at Skylight Ascend Wellness
I offer pharmacogenomic testing as part of my virtual psychiatric practice. Testing typically involves a painless cheek swab mailed to your home. After your results return from the lab, we’ll review them together and discuss how they may influence your treatment plan. This service is available to clients in Chicago, Springfield, St. Paul, Duluth, Orlando, Jacksonville and other communities across Illinois, Minnesota and Florida.
Key takeaways
Pharmacogenomic testing is a powerful tool for personalizing psychiatric care. It helps take the guesswork out of prescribing and promotes faster symptom relief with fewer side effects. If you’ve struggled to find the right medication, PGx testing may offer valuable insights. Contact me to see if this approach is right for you.
