Does the Medication response (PGx) test interact with medicines or supplements?

The Medication response (PGx) test does not add a drug to your body, so the swab itself does not interact with your medicines. It checks selected genetic factors related to drug metabolism. Your medicines do not change your inherited DNA, but they can affect how your body processes other medicines.

Give your clinician a full list of prescription drugs, over-the-counter medicines, vitamins, herbs, and supplements. Include any recent changes. A medicine that slows or speeds a drug-processing enzyme can affect treatment choices even when genetic findings suggest a certain metabolism pattern. Kidney function, liver function, and other health factors also matter.

Do not stop a medicine or supplement just to collect the sample unless your prescribing physician directs you to do so. Follow the kit label for any rules about food, drinks, or mouth care before swabbing. The report is not a complete check for drug interactions and cannot predict every side effect. Results vary. Ask your clinician or pharmacist to review your full medication list.
