Modern medications save millions of lives a year.
Yet any one medication might not work for you, even if it works for other people. Or it might cause severe side effects for you but not for someone else. Your age, lifestyle and health all influence your response to medications. But so do your genes. Scientists are working to match specific gene variations with responses to particular medications. With that information, doctors can tailor treatments to individuals. That's what pharmacogenomics is all about. Part of a new field called personalized medicine, pharmacogenomics offers the promise of predicting whether a medication is likely to help or hurt you before you ever take it.
