What is the maximum recommended dose of sertraline (selective serotonin reuptake inhibitor, SSRI)?

Maximum Recommended Dose of Sertraline

The maximum recommended dose of sertraline is 200 mg daily for most indications, including major depressive disorder, obsessive-compulsive disorder, panic disorder, PTSD, and social anxiety disorder. 1

Dosing Guidelines by Indication

Major Depressive Disorder and Obsessive-Compulsive Disorder (Adults)

• Initial dose: 50 mg once daily 1
• Dose range: 50-200 mg daily 1
• Dose adjustments should not occur at intervals less than 1 week due to sertraline's 24-hour elimination half-life 1

Panic Disorder, PTSD, and Social Anxiety Disorder

• Initial dose: 25 mg once daily for one week 1
• Increase to 50 mg once daily after first week 1
• Maximum dose: 200 mg daily 1

Premenstrual Dysphoric Disorder

• Initial dose: 50 mg daily (either throughout menstrual cycle or limited to luteal phase) 1
• Maximum dose: 150 mg daily when dosing throughout menstrual cycle, or 100 mg daily when dosing during luteal phase only 1

Pediatric OCD

• Children (6-12 years): Initial dose 25 mg once daily 1
• Adolescents (13-17 years): Initial dose 50 mg once daily 1
• Maximum dose: 200 mg daily 1

Dose Titration Considerations

• Dose increases should be made at intervals of not less than one week 1
• For patients not responding to 50 mg daily, dose may be increased in 50 mg increments 1, 2
• The starting dose of 50 mg/day is the usually effective therapeutic dose and optimal dose when considering both efficacy and tolerability for most patients 2

Special Populations

Elderly Patients

• No dosage adjustments are warranted for elderly patients solely based on age 3
• Unlike some other SSRIs, sertraline does not require altered dose recommendations in the elderly 2

Premature Ejaculation (Off-label Use)

• Daily doses of 25,50,100 or 200 mg or situational doses of 50 mg (4-8 hours before intercourse) have been shown to increase ejaculatory latency 4
• Higher doses may increase efficacy but may also be associated with increased frequency of erectile dysfunction and decreased libido 4

Pharmacokinetic Considerations

• Sertraline follows first-order kinetics with a plasma elimination half-life of 24-26 hours 5
• Therapeutic plasma concentration range is 10-50 ng/mL (level of recommendation: 3) 4
• At 50 mg daily dose, mean plasma concentration is approximately 12±17 ng/mL 4
• At 200 mg daily dose, mean plasma concentration is approximately 29±18 ng/mL 4

Adverse Effects at Higher Doses

• Higher doses may be associated with increased frequency of:
  • Erectile dysfunction and decreased libido 4
  • Gastrointestinal effects (nausea, diarrhea, dyspepsia) 5
  • Dry mouth, headache, insomnia, somnolence, dizziness, sweating 3

Important Cautions

• Avoid in patients with bipolar depression due to risk of mania 4
• Use with caution in patients under age 24 due to increased risk of suicidal ideation 6
• Serotonin syndrome is a potential serious complication, especially when combined with other serotonergic drugs 4

Clinical Pearl

While the maximum approved dose is 200 mg daily, clinical trials and practice suggest that most patients respond adequately to doses between 50-150 mg daily, with limited additional benefit but potentially more side effects at the maximum dose.
