Zoloft (Sertraline): Uses, Side Effects & What to Expect
Sertraline — sold as Zoloft — is one of the most prescribed antidepressants in the U.S. It’s an SSRI used for depression, anxiety, OCD, panic disorder, and PTSD. Early effects can appear in 1–2 weeks, with the full benefit usually taking 6–8 weeks. It is not addictive, but it should be stopped gradually with your prescriber.

What is sertraline?
Sertraline is a selective serotonin reuptake inhibitor (SSRI). It works by increasing the amount of serotonin — a chemical messenger tied to mood and calm — available between nerve cells in the brain. It’s sold under the brand name Zoloft and widely available as a generic.
What does Zoloft treat?
Sertraline is FDA-approved for a wide range of conditions: major depressive disorder, obsessive-compulsive disorder (OCD), panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder, and premenstrual dysphoric disorder (PMDD). Clinicians also commonly use it for generalized anxiety. That breadth is part of why it’s such a frequent first choice.
How long does it take to work?
Like other SSRIs, sertraline builds gradually. Some people notice early changes — steadier sleep, less anxiety — within the first one to two weeks, while the fuller benefit for mood typically develops over six to eight weeks. Consistency matters; stay in touch with your prescriber as you settle in.
Common side effects
Most side effects are mild and tend to ease after the first couple of weeks. The most commonly reported include:
- Nausea or digestive changes (including diarrhea)
- Headache
- Trouble sleeping
- Dry mouth
- Feeling drowsy or jittery early on
- Sexual side effects (such as lower libido)
If something is bothering you, reach out rather than stopping on your own — small adjustments often help.
An important safety note
Like all antidepressants, sertraline carries an FDA “boxed warning”: in children, teens, and young adults under 25, antidepressants can in rare cases increase suicidal thoughts, especially in the first few months or after a dose change. Close early follow-up is exactly how we manage this. If you or someone you love has thoughts of self-harm, call or text 988 (the Suicide & Crisis Lifeline) right away, and tell your prescriber about any new or worsening mood changes.
Stopping sertraline safely
Sertraline is not addictive, but your body adjusts to it — so stopping suddenly can cause discontinuation symptoms like dizziness, nausea, irritability, anxiety, and brief “brain-zap” sensory sensations. A gradual taper planned with your prescriber makes this far less likely.
A note on dosing
Dosing is individualized by your prescriber based on your diagnosis, age, other medications, and response — so this page intentionally doesn’t give a specific number. The aim is the lowest effective dose, adjusted with your clinician.
Frequently asked questions
What is Zoloft (sertraline) used for?
Sertraline (brand name Zoloft) is an SSRI antidepressant. It is FDA-approved to treat major depressive disorder, obsessive-compulsive disorder (OCD), panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder, and premenstrual dysphoric disorder (PMDD). Clinicians also use it for generalized anxiety.
How long does sertraline take to work?
Early effects like better sleep and reduced anxiety can show up in the first 1 to 2 weeks, while the full benefit for mood usually takes about 6 to 8 weeks. Keep taking it as prescribed even if the first couple of weeks feel slow.
What are the common side effects of Zoloft?
Common side effects include nausea, diarrhea or other digestive changes, headache, trouble sleeping, dry mouth, and sexual side effects. They are usually strongest in the first couple of weeks and often ease with time. Tell your prescriber about anything bothersome.
Is Zoloft addictive?
No. Sertraline is not a controlled substance and is not addictive. But you should not stop it abruptly — stopping suddenly can cause discontinuation symptoms, so your prescriber will help you taper gradually when it is time to stop.
How do I stop taking sertraline safely?
Always taper with your prescriber. Stopping too quickly can cause discontinuation symptoms such as dizziness, nausea, irritability, anxiety, and sensory disturbances. A gradual, planned step-down greatly reduces this risk.
Can I drink alcohol while taking Zoloft?
It is best to avoid or limit alcohol while taking sertraline, since alcohol can worsen drowsiness and dizziness and can work against the benefits for mood and anxiety. Talk with your prescriber about what is right for you.
