To talk about pharmacogenetics, we must define pharmacogenetics.
It is a specialty of biological sciences that studies the effect of genetic variants of an individual on their response to specific drugs.
Pharmacogenetics focuses on understanding how genetic differences between people affect the reactions and effects that a single medication has on everyone.
We have already discussed pharmacogenetics previously in the blog, highlighting how its importance has been increasing over the past few decades. It has answered many questions about the different effects of treatments on people, it is one of the pillars of current personalized medicine and precision medicine, and it has revolutionized many metabolic studies.
It breaks the concept of populations as a homogeneous group and demonstrates that there are significant differences even among individuals who are closely related and look similar.
Drugs are usually prescribed in doses based on universal and obvious criteria, such as a person’s age or weight.
Unfortunately, patient alleles are not a criterion that is typically easily observed and are often overlooked.
The same treatment, which has demonstrated effectiveness, can be completely ineffective for one person or even cause adverse reactions. Only a few specific mutations at key points in the genome are needed for these distorted effects to occur.
This does not mean that clinical trials have been conducted incorrectly. The genetic variability of the human species is immense, and it is impossible for a single medication to account for all the factors.
Similarly, it is not only useful to rule out methodologies that may harm the patient. It allows finding the medications that will have the best effect with the least possible side effects.
Another aspect of pharmacogenetics is to analyze each person’s medication compatibility: one of the results sections that we offer in our genetic analysis.

These new medications will be gradually incorporated into users as we update our database.
People who purchase the product from now on (May 2025) will have these reports when their results arrive.
In both cases, users do not have to pay anything or take any additional action. We take care of everything.
In the future, following our line of work, more updates and content will be added to this and other sections of our tellmeGen reports.
You can see everything that the genetic analysis of tellmeGen offers on our website. Today we give you more than yesterday, but less than tomorrow.
Still think it’s not enough? You have another additional option. Optimize your health with a personalized pharmacogenetic report.
