Sertraline: What to Know Before You Start

Sertraline can help with depression, anxiety, panic, OCD, and PTSD. It works for many people, but knowing how it behaves and what to watch for makes a big difference. Read this if you’re starting sertraline, switching from another antidepressant, or just want to manage side effects better.

How sertraline works and what to expect

Sertraline is an SSRI—it raises serotonin in the brain to improve mood and lower anxiety. Most people start feeling small improvements in 1–2 weeks, with clearer change by 4–6 weeks. Full effects can take up to 12 weeks. If you don’t notice progress after a couple months, talk with your prescriber about dose changes or trying another option.

Typical starting doses are 25–50 mg daily for adults, often increased slowly to a usual range of 50–200 mg. Doctors tailor dose based on symptoms, side effects, and other meds you take.

Side effects, interactions, and practical tips

Common side effects include nausea, trouble sleeping or feeling sleepy, sexual changes (lower libido or delayed orgasm), dry mouth, sweating, and mild shaking. These often improve after 2–4 weeks. If side effects are intense, your doctor can lower the dose, change timing, or switch medicines.

Watch for serious issues: new worsening mood or suicidal thoughts (especially in young adults), severe allergic reactions, or signs of serotonin syndrome. Serotonin syndrome symptoms include high fever, fast heartbeat, muscle stiffness, agitation, and confusion—seek emergency care if these happen.

Interactions matter. Don’t combine sertraline with MAO inhibitors (you usually need a 14-day gap). Be cautious with triptans, certain antipsychotics, and some migraine drugs—these raise serotonin risk. Blood thinners and NSAIDs can increase bleeding risk while on sertraline. Tell your provider about all prescriptions, over-the-counter meds, and supplements like St. John’s wort.

Stopping suddenly can cause withdrawal symptoms: dizziness, flu-like aches, irritability, and vivid dreams. To avoid that, your doctor will taper the dose gradually. If you’re switching from fluoxetine, the timeline differs—your prescriber will plan the proper gap.

Practical tips: take sertraline at the same time each day, keep a simple pill chart, and use food to reduce nausea. Avoid alcohol if you notice more drowsiness or mood swings. If you’re pregnant, planning pregnancy, or breastfeeding, talk to your doctor about risks and benefits—sertraline is sometimes used in pregnancy, but it’s a personal decision with your clinician.

If sertraline isn’t helping, there are options: another SSRI, SNRI, augmenting with therapy, or combining meds under a doctor’s care. Don’t make changes alone.
