Pharmacogenomics
Why Your Genes Matter When It Comes to Your Medications
If there's one thing I've learned after years studying health and now working in private practice, it's that medications can be truly life-changing…when they're the right fit.
And when they're not? Ugh. Side effects, trial-and-error, and a whole lot of people walking away feeling like they are the problem. Usually, they're not. It's often just the way their body processes certain drugs.
That's where pharmacogenomics comes in.
Pharma… what?
Pharmacogenomics, PGx for short, looks at how your genes influence the way your body processes medications.
Some people break down certain drugs too quickly. Some too slowly. Some in a way that leads to side effects that never quite make sense on paper. And here's the tricky part: it's not something you can feel or guess your way to. It doesn't show up on a standard lab panel or in how you describe your symptoms.
When we understand this piece, we can choose medications that are more likely to work well for you from the start instead of finding out over three months and two dose changes that a particular drug was never going to be a good match.
When PGx can be especially helpful
A few situations where it tends to make the biggest difference:
Someone about to start treatment for depression, anxiety, or chronic pain
Anyone with a pattern of side effects or nonresponse, the "I've tried four things and nothing works" experience
People taking multiple medications, where interactions and metabolism get complicated fast
Anyone who wants a more individualized approach to their care
Genetic results are one piece of information. They don't prescribe, adjust, or stop anything on their own. The bigger picture
I always tell my own patients: PGx isn't just for the complicated cases.
It can be used proactively to reduce guesswork, support safer prescribing, and strengthen trust in the whole treatment process. There's something genuinely different about starting a medication knowing your body is likely to handle it well, rather than crossing your fingers and waiting to see.
You deserve care that accounts for how your body works. This is one more way to get there.
Curious if this type of testing might be helpful?
