Treatment with Cerdelga

  1. Is Cerdelga right for you?

    Before your doctor can determine if you are a candidate to take Cerdelga, he or she must determine your CYP2D6 metabolizer status. A genetic test (a simple blood test) can determine your CYP2D6 metabolizer status.

    Understanding whether treatment with Cerdelga is right for you starts by understanding your CYP2D6 metabolizer status. CYP2D6 metabolizer status describes your body’s ability to break down (metabolize) certain drugs, including Cerdelga.
