Starting a new medication like sertraline (commonly known by the brand name Zoloft) can feel overwhelming, especially if you’re unsure what to expect. Sertraline is a selective serotonin reuptake inhibitor (SSRI) often prescribed for depression, anxiety, and other mental health conditions. While it can be highly effective, the first few days of taking sertraline may come with some adjustments. In this article, we’ll walk you through what you might experience during the initial days and how to manage any side effects.
What Is Sertraline?

Sertraline is an antidepressant that works by increasing the levels of serotonin in the brain. Serotonin is a neurotransmitter that helps regulate mood, sleep, and appetite. By balancing serotonin levels, sertraline can help improve symptoms of depression, anxiety, panic disorder, and obsessive-compulsive disorder (OCD).
It’s important to note that sertraline is not a quick fix—it typically takes 4-6 weeks to feel its full effects. However, you may notice some changes, both positive and challenging, within the first few days.
