How to know which medication works best for me based on my genetics?

Have you ever taken a medication that "should" work and simply had no effect? Or that caused you side effects while it works wonders for others? It's no coincidence: your genetics largely determines how your body processes and responds to drugs.

A pharmacogenetic test lets you know in advance which medications will work best for you, which could cause problems, and for which you might need to adjust the dose. Here's how.

How does genetics influence medication response?

Your body has enzymes, encoded by genes, that process and eliminate drugs. Small variations in those genes can make a medication more effective, less effective or riskier for you. That's why two people on the same dose can have completely different experiences.

How to know which medication works best for me?

The objective way to find out is a pharmacogenetic test. At Ajolote Azul, the PGx Test analyzes more than 100 medications across 10 therapeutic categories (analgesics, antidepressants, anticoagulants, cholesterol drugs, ADHD medications, anticonvulsants and more).

The report clearly shows you:

• Medications that will probably work well for you.
• Medications that may be less effective in your case.
• Medications with higher risk of side effects based on your genes.
• Specific recommendations to share with your doctor.

What medications can it analyze? Real examples

These cases show why genetic information matters:

| Medication | Key gene | What the test can reveal | | ----------- | -------- | ----------------------------------------------------------------------------------------------- | | Codeine | CYP2D6 | If you convert it to morphine too quickly (strong side effects) and an alternative is advisable | | Tamoxifen | CYP2D6 | If it could be less effective, to consider other options from the start | | Clopidogrel | CYP2C19 | If you're a poor metabolizer and the anticoagulant doesn't protect you well |

When should you stop the "trial and error" approach?

Instead of spending weeks or months trying different medications until you find the right one, you can arrive at your appointment with objective information about your genetics. This makes especially good sense when:

1. You've had unexpected side effects.
2. A treatment hasn't worked as expected.
3. You're about to start long-term therapies (cardiology, psychiatry, oncology).
4. You want to reduce risks and speed up finding the right treatment.

Ajolote Azul's PGx Test costs $9,800 MXN and includes a clinical report ready to share with your doctor.

In summary: your genetics already knows how your body responds

Pharmacogenetics turns "trial and error" into informed decisions. Knowing which medications work best for you saves time, reduces risks and increases your treatment's chances of success. The final decision is always your doctor's, but now with better information.
