SSRIs: Uses, Benefits, Side Effects & Dapoxetine Guide (2026 Update)

Selective Serotonin Reuptake Inhibitors (SSRIs) remain a cornerstone of mental health and sexual wellness treatment worldwide. Often searched as "SSRTI" by mistake, these medications help millions manage depression, anxiety, OCD, and — uniquely with Dapoxetine — premature ejaculation. In Pakistan, brands like Cipralex, Zoloft, Prozac, and Everlong (Dapoxetine) are widely prescribed.

This comprehensive guide covers how SSRIs work, common types (including Dapoxetine), benefits, side effects, and key considerations for safe use.

SSRIs: Uses, Benefits, Side Effects 

What Are SSRIs and How Do They Work?

SSRIs increase serotonin levels in the brain by blocking its reuptake into neurons. Serotonin regulates mood, sleep, appetite, and ejaculatory control.

Mechanism step-by-step:

Serotonin release into the synapse.

Reuptake normally recycles it quickly.

SSRIs inhibit the transporter → 

more serotonin available.

Enhanced signaling → 

mood improvement (2–6 weeks) or delayed ejaculation (Dapoxetine: 1–3 hours onset).

Daily SSRIs build adaptive brain changes; Dapoxetine offers rapid, on-demand action due to its short half-life.

Common SSRIs: Types and Primary Uses
