Did you know your DNA may affect how well your anti-nausea medication works?
CPIC — the organization that sets the gold standard for pharmacogenomics guidelines — just released a major 2026 update. It now covers ALL of the most commonly prescribed anti-nausea medications, including ondansetron (Zofran), granisetron, and palonosetron.
Here's the simple version: Some people are "Ultrarapid Metabolizers" of a liver enzyme called CYP2D6. That means their body may process certain anti-nausea medications so quickly that the drug doesn't have time to work — which can lead to breakthrough nausea, especially during chemotherapy or after surgery.
The good news? There are alternative medications that work differently — and a genetic test can help identify which option may be the better fit for you.
This update now also includes children, which is a meaningful step toward more personalized care for younger patients going through difficult treatments.
At MedGenyx, we specialize in exactly this kind of personalized medication guidance. We help you and your care team understand what your DNA may mean for how your body handles the medications you've been prescribed.
