Sertraline: Uses, Side Effects, And Essential Facts

Sertraline is a selective serotonin reuptake inhibitor (SSRI) antidepressant commonly prescribed for depression, various anxiety disorders, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and premenstrual dysphoric disorder (PMDD).

About sertraline

Sertraline belongs to the class of medications known as selective serotonin reuptake inhibitors (SSRIs). These drugs work by increasing serotonin levels in the brain, a neurotransmitter that regulates mood, helping to alleviate symptoms of mental health conditions.

Sertraline is available in tablet form in the UK and USA, with strengths of 50 mg and 100 mg. Oral liquid formulations are also available in some regions.

What is sertraline used for?

Sertraline treats a range of mental health conditions by enhancing serotonin availability in the brain, which improves mood regulation and reduces symptoms like persistent sadness, excessive worry, intrusive thoughts, and compulsive behaviors.

• Depression (major depressive disorder): Helps relieve low mood, loss of interest, and other symptoms that interfere with daily life.
• Anxiety disorders: Includes panic disorder (sudden panic attacks), social anxiety disorder (fear of social situations), PTSD (symptoms after trauma), and generalized anxiety.
• Obsessive-compulsive disorder (OCD): Reduces unwanted repetitive thoughts (obsessions) and behaviors (compulsions).
• Premenstrual dysphoric disorder (PMDD): Manages severe premenstrual mood swings, irritability, and depression.

Clinical studies confirm sertraline’s efficacy in these areas, with improvements in cognition for depressed patients and fewer sedative effects compared to older antidepressants.

How does sertraline work?

Sertraline inhibits the reuptake of serotonin in the brain, allowing more of this chemical to remain active between nerve cells. This balances mood, reduces anxiety, and diminishes OCD symptoms over time.

Unlike tricyclic antidepressants, sertraline has minimal anticholinergic, antihistamine, or adrenergic effects, making it better tolerated with less impact on heart function or cognition.

Before taking sertraline

Consult your doctor before starting sertraline, especially if you have certain health conditions or take other medications.

Who can and cannot take sertraline

Sertraline is suitable for adults and children over 6 for OCD (under specialist supervision). It is not recommended if you have allergies to SSRIs, are taking MAOIs, or have uncontrolled bipolar disorder.

Taking sertraline with other medicines and herbal supplements

Sertraline interacts with MAOIs, pimozide, NSAIDs (bleeding risk), warfarin, and St John’s wort (serotonin syndrome risk). Inform your doctor of all medications.

Take sertraline once daily, morning or evening, with or without food. Aim for the same time each day.
