Understanding Sertraline (Zoloft)
Sertraline, often known by the brand name Zoloft, is a selective serotonin reuptake inhibitor (SSRI) approved by the FDA in 1991. It works by increasing the levels of serotonin, a neurotransmitter in the brain, which helps improve mood and reduce anxiety. It is prescribed for various conditions, including major depressive disorder (MDD), obsessive-compulsive disorder (OCD), and panic disorder.

Common and Short-Term Side Effects
When starting sertraline, side effects may occur as the body adjusts. These are typically mild and often improve within the first couple of weeks.
Common side effects include:
- Nausea, diarrhea, or dry mouth
- Headache
- Insomnia or feeling sleepy
- Dizziness
- Sexual problems, such as decreased libido
Taking the medication with food can help with nausea, and taking it in the morning may reduce sleep disturbances.
Serious Health Risks and Potential Damage
While many side effects are temporary, sertraline carries risks of more severe health issues that require immediate medical attention.
Serotonin Syndrome
This is a rare but life-threatening condition resulting from excessive serotonin levels, especially when sertraline is combined with other serotonin-affecting medications. Symptoms include agitation, confusion, rapid heartbeat, high blood pressure, muscle rigidity, and fever.
Increased Bleeding Risk
Sertraline can affect blood clotting, increasing the risk of bleeding, particularly when taken with other blood-thinning medications. This can manifest as bruising, nosebleeds, or more serious internal bleeding.
Suicidal Thoughts
A boxed warning highlights an increased risk of suicidal thoughts and behaviors in young people starting antidepressants like sertraline, particularly during the first few months of treatment or after dose adjustments.
Hyponatremia (Low Sodium Levels)
Sertraline can lower blood sodium levels, a condition that can be serious, especially for older adults. Symptoms can range from headache and confusion to seizures and coma in severe cases.
Organ-Specific Concerns
- Liver: Rare cases of liver problems have been reported. Jaundice (yellowing of skin or eyes) requires immediate medical attention.
- Heart: Sertraline may rarely cause an irregular heart rhythm (QT prolongation), a higher risk for individuals with pre-existing heart conditions or electrolyte imbalances.
- Eyes: There's a risk of angle-closure glaucoma, a rapid increase in eye pressure, which can lead to vision loss if not treated promptly.
Long-Term Health Damage
While long-term sertraline use is generally safe for many, potential long-term risks have been identified. These include weight gain, persistent sexual dysfunction (potentially PSSD), emotional blunting, reduced bone density, and a possible link to type 2 diabetes.
| Feature | Common Side Effects | Serious/Long-Term Risks |
|---|---|---|
| Frequency | Often occur, especially when starting | Rare, but can be severe |
| Symptoms | Nausea, headache, insomnia, dizziness, diarrhea, sexual issues | Serotonin syndrome, suicidal thoughts, bleeding, hyponatremia, weight gain |
| Duration | Typically transient (1-2 weeks) | Can be persistent or require immediate medical intervention |
| Management | Often managed with simple measures (taking with food, dose timing) | Requires immediate medical attention and may involve stopping the drug |
Discontinuation Syndrome (Withdrawal)
Stopping sertraline suddenly can lead to withdrawal symptoms, known as discontinuation syndrome.
Common withdrawal symptoms include:
- Dizziness and imbalance
- "Brain zaps" (electric shock-like sensations)
- Nausea and flu-like symptoms
- Anxiety, irritability, and agitation
- Insomnia and vivid dreams
A gradual tapering of the dose under medical supervision is recommended.
Conclusion
Like any medication, sertraline carries potential risks. While common side effects are usually mild and temporary, serious short-term risks and potential long-term damage, particularly concerning weight, sexual function, and metabolic health, are important considerations. For many, the benefits in treating conditions like depression and anxiety outweigh these risks. The decision to use sertraline should involve a thorough discussion with a healthcare provider to weigh individual benefits against potential harm, ensuring proper monitoring and a safe plan for use and discontinuation.
