Sertraline Dosage and Efficacy

Comparative Efficacy and Safety

Sertraline has been shown to increase ejaculatory latency at doses ranging from 25 to 200 mg daily or situationally at 50 mg (4-8 hours before intercourse) 1, 2, 3
Higher doses of sertraline may increase efficacy but could potentially be associated with increased frequency of erectile dysfunction and decreased libido 3
Unlike some other SSRIs, sertraline has a relatively favorable drug interaction profile due to less effect on CYP450 isoenzymes 4, 5
Sertraline has a recommended therapeutic plasma concentration range of 10-50 ng/mL 6

Common side effects include nausea, dry mouth, drowsiness, reduced libido, headache, insomnia, and dizziness 1, 2
A discontinuation syndrome can occur with abrupt cessation, characterized by dizziness, fatigue, headaches, nausea, insomnia, sensory disturbances, and anxiety 4, 5
Unlike fluoxetine which has a very long half-life, sertraline has a shorter half-life requiring more gradual discontinuation to avoid withdrawal symptoms 4
Monitoring for suicidal thinking and behavior is recommended, especially in the first months of treatment and following dosage adjustments 7

When switching from fluoxetine 40 mg to sertraline, consider the long half-life of fluoxetine and its active metabolite (1-3 days and 7-15 days respectively), which may require a washout period 8, 4
Avoid concomitant use with MAOIs due to risk of serotonin syndrome 4, 5
