Pharmacogenomics is the study of how our DNA can affect our responses to certain drugs. These variations can be determined through genetic blood testing so your psychiatrist can identify the best medication for your specific genetic makeup. Results also can be used to determine environmental factors, such as diet, lifestyle, and age, which contribute to drug effectiveness, or even identify what diseases you are most at risk for developing.
Genetic testing essentially allows your medications to be “tailor-made.” This is important given that your variations can make you either metabolize medications too quickly (making them ineffective), or too slowly (which increases side effects as they remain in your bloodstream too long). Thus, your doctor can give you personalized medicine and make your treatment more effective.
