And so is your response to drugs.
If everyone responded the same way to medications, we would only have one antidepressant and one pain reliever on the market. The reality is very different. Medications that work for one person often don’t work well for another, and a lot of this variation is determined by our genes. This is true for all kinds of medications: over the counter remedies, prescription drugs, and even cannabis products.
Your unique genes play an important role in your individual response to different medications. The science of pharmacogenetics is the study of how genetics impact your body's ability to break down and respond to different medications.
