Epigenetic Effects of Citalopram
Taking citalopram now, or in the past? What one study found about how it may change the way genes are switched on and off, and why that matters.

Wondering about the long-term effects of citalopram? Citalopram is commonly prescribed for depression and anxiety, and it is known to be effective. But one study suggests it might also change the way your genes are expressed.
So how does the medicine work, and what did the study find?
How Does Citalopram Work?
Citalopram, an SSRI (Selective Serotonin Reuptake Inhibitor), works by increasing the availability of serotonin in the brain. While this helps alleviate symptoms of depression, the drug also interacts with various other biological systems, which might explain some of its side effects.
Epigenetic Changes: The Hidden Impact
Recent research has revealed that citalopram can cause significant changes in DNA methylation. Essentially, it can alter the way your genes are expressed without changing the underlying DNA sequence. This study found that after 30 days of exposure to citalopram, 626 gene promoters showed significant differential methylation. This could lead to long-term health repercussions, especially in systems related to the nervous system, cellular growth, and even reproductive health.
Why It Matters
These findings suggest that the effects of citalopram might not end when the medication is discontinued. Epigenetic changes could potentially persist, affecting your health in ways that are not yet fully understood. This research underscores the importance of considering long-term risks when using pharmaceuticals like citalopram.
Takeaway
If you or someone you know is using citalopram, it might be worth discussing these potential risks with a healthcare provider. Understanding both the benefits and potential long-term effects is crucial for making informed decisions about your mental health treatment.
