Different bodies react differently to medication. Here are a few examples. 

James, 65

After experiencing a sudden onset of severe abdominal pain, James was hospitalized with a perforated peptic ulcer. Due to his prolonged immobility during treatment, he developed a blood clot in his lung. James was prescribed a common blood thinner (anticoagulant) to prevent recurrence of blood clots. 


A few days after starting the blood thinner, James experienced significant bleeding in his gastrointestinal tract and required emergency surgery. The doctors were puzzled by James’ extreme reaction to the blood thinner, as the medication was prescribed at the standard starting dose. 


Seeking answers, James’ healthcare team had his DNA tested with DecisionRx. His results revealed James had a genetic variation in two genes (CYP2C9 and VKORC1) that affected the metabolism of, and sensitivity to, the blood thinner. He should have been prescribed half the standard initial dose. 

When his dose was tailored to his unique genetic makeup, James responded to the drug as intended, receiving the protection from future blood clots he needed. 

Susan, 70

While Susan was taking the diuretic furosemide to help with fluid overload, her doctors advised her to add an over-the-counter potassium supplement as furosemide can lower potassium levels in the body. Because it is not a prescription medication, this supplement was never added to her formal medication list. 

A few years later, Susan was switched to a different diuretic that actually increases potassium levels. Yet, Susan continued to use her potassium supplement.

Because the DecisionRx pharmacist had access to both her full prescription and supplement lists, they were able to recommend stopping Susan’s potassium supplement before she experienced severe complications from elevated potassium in the body—which include life-threatening arrhythmias and heart failure.

Andrew, 68

Andrew struggled with severe depression and had tried three different antidepressant medications without success. Desperate for relief, he turned to DecisionRx to find answers. His DNA test results revealed a medication more likely to be effective based on his genetic profile. Andrew finally found relief from his symptoms with the new medication, and his depression remained controlled.

Unfortunately, 5 years later, Andrew suffered a heart attack and required treatment with clopidogrel—a common antiplatelet drug. Remembering his pharmacogenomic report, he asked his doctors to ensure the medication was compatible with his genetics. The report indicated a mutation that would render clopidogrel ineffective in preventing another heart attack.

With this information, his doctors prescribed an alternative antiplatelet medication, helping Andrew avoid potential complications and receive the appropriate treatment at the earliest opportunity.
