CYP2C9

CYP2C9 is a gene that produces an enzyme in your liver responsible for breaking down certain medications, such as blood thinners like warfarin. Variations in this gene can affect how quickly or slowly you process these drugs, influencing their effectiveness and the risk of side effects. Understanding your CYP2C9 status helps doctors personalize medication doses to ensure safe and effective treatment. Essentially, CYP2C9 acts as a biological regulator, playing a key role in drug metabolism and response.
