If you’re deciding between escitalopram and citalopram, you’re not alone. These are two of the most commonly prescribed SSRIs (selective serotonin reuptake inhibitors) in the UK, particularly for anxiety and depression. They’re closely related medications, and they’re often discussed as if they’re almost interchangeable. In fact, both are influenced by a key drug-metabolising enzyme pathway called CYP2C19, which helps your body process and clear certain SSRIs.

Pharmacogenetic testing—often shortened to PGx testing—is a type of DNA test that shows how your body processes medicines. Instead of relying on trial and error, PGx can help your doctor choose the right medication and dose from the start. Whether you’re considering antidepressants, pain medication, or heart drugs, PGx testing at home in the UK makes personalised prescribing more accessible than ever.
Pharmacogenetic testing—also known as PGx testing—can reveal why some medicines work well for one person but not for another. If you’ve ever wondered why antidepressants, painkillers, or heart medicines affect people so differently, PGx offers the answer.
Pharmacogenetic testing—often called PGx testing—is quick, simple, and painless. Many patients in the UK are now exploring DNA cheek swab tests for medicines, including antidepressants, ADHD treatments, painkillers, and heart medications. If you’ve wondered what actually happens when you order a test, here’s what to expect.
Pharmacogenetic testing—also known as PGx testing—is completely safe and designed only to help your doctor personalise your medication. Many patients worry about privacy or whether a DNA test reveals more than they’d like. In reality, PGx testing looks only at genes that affect how you process medicines, and in the UK, results are protected under strict data privacy laws like GDPR.
If you’ve ever had side effects from medicines—things like nausea, dizziness, or fatigue—you know how disruptive they can be. Pharmacogenetic testing (PGx) can help explain why these reactions happen and, more importantly, help your doctor choose treatments that reduce the risk.

Citalopram is often described as a “cleaner” SSRI because it mostly targets serotonin alone. It can be a good choice for anxiety, but at higher doses it sometimes carries a risk of affecting heart rhythm. Sertraline, on the other hand, also nudges dopamine a little — which can help with motivation and energy. It tends to have fewer issues with the heart and fewer drug–drug interactions.

Pharmacogenomic testing is becoming increasingly important, particularly in the UK where interest in personalised medicine is growing. But what exactly is it? A pharmacogenomic test is a type of genetic testing for psychiatric medications and other treatments. It's a DNA test that shows how your body responds to different medications.
Published 01/04/2025
A pharmacogenomic test—sometimes called an at-home DNA test for medications—is collected just like most DNA tests: with a simple mouth or buccal swab, collecting cells from the inside of your cheek. This is then sent to our accredited laboratory, where your DNA is analysed and compared with published data on how different genetic types respond to various medications.
