Your genetic makeup does have an impact on the way your body uses medication. There is quite a bit of existing research and more is currently underway in this area of study, called pharmacogenomics.
Everyone’s body has a different way of processing, or metabolizing, drugs. That means everyone responds to medications in a slightly different way. For some people, a medication may work well with little or no side effects. For others, the same medicine may not work at all, or it may cause significant side effects. That happens for many reasons, including age, health and lifestyle. Research has shown that subtle differences in a person’s genes also have an impact on medication metabolism.
