Precision Medicine vs. Traditional Prescribing: Why Your DNA Holds the Key

The Problem with One-Size-Fits-All Prescriptions

For decades, doctors have prescribed medications using a trial-and-error approach. If one medication doesn’t work or causes unwanted side effects, the patient tries another—sometimes cycling through multiple drugs before finding the right fit.

While this method works for some, it can be frustrating, costly, and even dangerous for others. Have you ever taken a medication that didn’t seem to help? Or worse—one that caused severe side effects? If so, you're not alone.

That’s where precision medicine comes in.

By using pharmacogenomics (PGx)—the study of how your genes affect medication response—doctors can move away from the traditional guessing game and toward treatments tailored specifically to you.

What Is Precision Medicine?

Precision medicine is an innovative healthcare approach that uses genetic information to customize treatments for individuals. Instead of relying solely on symptoms, age, weight, or general population trends, doctors analyze your DNA to determine which medications are likely to be most effective for you.

This approach is particularly useful for:

• Mental health medications (antidepressants, anxiety meds, ADHD treatments)

• Pain management (opioids, NSAIDs, and muscle relaxers)

• Cardiovascular drugs (blood thinners, beta blockers, statins)

• Cancer treatments (targeted therapies based on genetic markers)

Aspect	Traditional Prescribing	Precision Medicine (PGx Testing)
Approach	Trial and Error	DNA-based personalized treatment
Medication Selection	Based on population averages	Based on your unique genetic makeup
Risk of Side Effects	Higher risk of adverse reactions	Reduced risk, as medications are chosen based on how your body metabolizes them
Effectiveness	May take multiple tries to find the right drug	Increases the chances of the first medication working
Time & Cost	More doctor visits, multiple prescriptions	Fewer medication adjustments, saving time and money

Real-Life Success Stories

Case 1: Sarah’s Battle with Depression

Sarah struggled for years with depression and anxiety, trying multiple antidepressants with little success. After a pharmacogenomic test, her doctor discovered that her body metabolized certain antidepressants too quickly, making them ineffective. A switch to a genetically compatible medication made a dramatic improvement in her symptoms within weeks.

Case 2: James and Pain Management

James had knee surgery and was prescribed a common opioid for pain relief. Instead of helping, the medication made him nauseous and barely managed his pain. After pharmacogenomic testing, doctors found that his genes caused poor metabolism of that particular drug. They adjusted his prescription to a more suitable medication, providing better pain relief with fewer side effects.

How to Get Started with Precision Medicine

If you're tired of the trial-and-error approach, getting a pharmacogenomic test is the first step toward personalized medicine.

How It Works:

✔️ Order a PGx test (TryPGx.com).

✔️ Provide a simple DNA sample (simple cheek swab).

✔️ Receive a personalized medication plan from our certified pharmacist based on your genetic makeup.

✔️ Work with your doctor or a specialist to adjust your prescriptions accordingly.
