What side effects can the Medication response (PGx) test cause?
Short answer
The Medication response (PGx) test uses a cheek swab and does not expose you to a drug. Swabbing may cause brief mouth discomfort or irritation, especially if you press too hard. Use the kit as directed. Contact a clinician for bleeding, lasting pain, or other concerning symptoms.
The Medication response (PGx) test collects cells from inside your cheek. It does not involve taking a medicine or drawing blood. The main physical concern is local discomfort or irritation from rubbing the swab against your mouth. Pressing too hard or swabbing an injured area may cause irritation or minor bleeding.
Follow the kit label and your prescribing physician’s directions. Do not scrub harder or longer than instructed. If you have mouth sores, recent dental work, active bleeding, or another mouth problem, ask whether you should wait before collecting the sample. Stop collection if it causes pain or bleeding, and ask for guidance. Seek medical care for heavy bleeding or symptoms that do not settle.
Genetic information can also raise questions or cause worry about treatment choices. The report cannot tell you with certainty whether a medicine will work or cause side effects. Results vary. Review findings with your treating clinician rather than stopping a medicine because a report seems concerning.
