From the Guidelines
Concurrent use of levetiracetam and sertraline is generally considered safe in patients with seizure disorders and depression, but caution is advised due to the potential risk of serotonin syndrome and increased seizure risk. When managing the interaction between these medications, it is essential to monitor patients closely for potential side effects, particularly during the initial combination period. According to the clinical practice guideline for the assessment and treatment of children and adolescents with anxiety disorders 1, SSRIs, including sertraline, should be used cautiously in patients with a history of a seizure disorder. Some key considerations for managing this interaction include:
- Monitoring for signs of serotonin syndrome, such as mental status changes, neuromuscular hyperactivity, and autonomic hyperactivity, which can be triggered by elevated brain serotonin levels 1
- Being aware of the potential for increased seizure risk with sertraline, particularly in patients with a history of seizure disorders 1
- Gradually titrating sertraline to minimize the risk of side effects, starting at a low dose (e.g., 25 mg daily) and increasing slowly as needed and tolerated
- Maintaining regular follow-up appointments to assess both seizure control and depression symptoms, with adjustments made based on individual response. It is crucial to weigh the benefits of using levetiracetam and sertraline together against the potential risks and to consider alternative treatment options if necessary.

From the Research
Interaction between Levetiracetam and Sertraline
The interaction between levetiracetam (Keppra) and sertraline (Zoloft) in patients with seizure disorders and depression is a complex issue.
- There is limited direct evidence on the interaction between these two specific medications 2, 3, 4, 5, 6.
- However, it is known that levetiracetam can cause neuropsychiatric side effects, including behavioral disturbances, mood symptoms, and suicidality 3.
- Sertraline, on the other hand, is a selective serotonin reuptake inhibitor (SSRI) that can be used to treat depression in patients with epilepsy, with a relatively low risk of seizure worsening 6.
Recommendations for Managing the Interaction
- Patients with seizure disorders and depression who are taking levetiracetam and sertraline should be closely monitored for signs of neuropsychiatric side effects and seizure worsening 3, 6.
- The dosage of levetiracetam and sertraline should be adjusted according to the patient's response and tolerance, with regular assessments of seizure frequency and depressive symptoms 4, 6.
- Healthcare providers should be aware of the potential for levetiracetam to cause behavioral abnormalities, particularly in patients with a history of psychiatric disorders 3.
- The use of sertraline in patients with epilepsy and depression can be a good therapeutic option, considering its efficacy in remission of depressive symptoms and maintenance of satisfactory seizure control 6.
Key Considerations
- The mechanism of action of levetiracetam involves binding to synaptic vesicle protein 2A (SV2A), which can lead to neuronal inhibition and potentially interact with sertraline's mechanism of action 3, 5.
- The prevalence of neurobehavioral symptoms associated with levetiracetam use is increased in predisposed individuals, highlighting the need for careful patient selection and monitoring 3.
- Regular follow-up and open communication between healthcare providers and patients are essential for managing the interaction between levetiracetam and sertraline and optimizing treatment outcomes 2, 4, 6.
