CYP2D6

CYP2D6 is a gene that produces an enzyme in the liver responsible for breaking down many medications, such as antidepressants, painkillers, and heart drugs. People have different versions of this gene, which can influence how quickly or slowly their body processes these medicines. This variability can affect how effective a drug is or whether it might cause side effects. Understanding your CYP2D6 status can help healthcare providers personalize medication choices and dosages for safer and more effective treatment.
