What is a common side effect of SSRIs, particularly noted with over 30% of patients?

The common side effect of SSRIs (Selective Serotonin Reuptake Inhibitors) that affects over 30% of patients is sexual dysfunction, specifically anorgasmia, which is the inability to achieve orgasm despite adequate sexual stimulation. SSRIs increase the levels of serotonin in the brain, which can interfere with the normal sexual response cycle. This effect can encompass various aspects of sexual function, including reduced libido, delayed ejaculation in men, and difficulties achieving orgasm in both men and women.

Sexual dysfunction is a significant concern for many patients as it can impact their quality of life and adherence to medication. Understanding this side effect is crucial for healthcare professionals when discussing treatment options for depression and anxiety and for making informed decisions about managing any negative outcomes that might arise from SSRI usage.

Other options listed, such as weight gain, anxiety, and insomnia, can indeed occur with SSRIs but are less prevalent compared to sexual dysfunction. Each of these side effects varies from patient to patient, and not all will experience them; hence, it is vital to monitor and communicate about any side effects during treatment.
