What is the typical dosing regimen for Zoloft (sertraline)?

Zoloft (Sertraline) Dosing Regimen

The typical dosing regimen for Zoloft (sertraline) starts at 50 mg once daily for most indications, with the option to increase to a maximum of 200 mg daily based on clinical response, with dose adjustments occurring at intervals of no less than one week. 1

Initial Dosing by Indication

• Major Depressive Disorder and Obsessive-Compulsive Disorder (Adults): Start with 50 mg once daily 1
• Panic Disorder, PTSD, and Social Anxiety Disorder: Start with 25 mg once daily for one week, then increase to 50 mg once daily 1
• Premenstrual Dysphoric Disorder: Start with 50 mg daily (either throughout the menstrual cycle or limited to the luteal phase) 1
• OCD in Children (6-12 years): Start with 25 mg once daily 1
• OCD in Adolescents (13-17 years): Start with 50 mg once daily 1

Dose Titration

• For most patients, 50 mg/day is the usually effective therapeutic dose and optimal when considering both efficacy and tolerability 2
• For patients not responding adequately to initial dosing, increase in 50 mg/day increments 1
• Allow at least one week between dose adjustments due to sertraline's 24-hour elimination half-life 1
• Maximum recommended dose is 200 mg/day for most indications 1

Administration Timing

• Sertraline can be administered as a single daily dose at any time of day (morning or evening) 1, 2
• No specific requirement to take with or without food, though taking with food may help reduce initial gastrointestinal side effects 3

Special Populations

• Elderly Patients: No dosage adjustments are required based solely on age 4, 5
• Hepatic Impairment: Use with caution; lower doses or less frequent dosing may be needed 1
• Renal Impairment: No specific dose adjustments recommended in the FDA labeling 1

Duration of Treatment

• For major depressive disorder, maintenance treatment is generally recommended for several months beyond initial response 1
• Studies have demonstrated maintained antidepressant efficacy for up to 44 weeks following 8 weeks of initial treatment 1
• Periodic reassessment is recommended to determine the need for continued maintenance treatment 1

Common Side Effects to Monitor

• Gastrointestinal effects: nausea, diarrhea, loose stools, dyspepsia 3
• Central nervous system effects: headache, insomnia, somnolence, dizziness 4
• Other effects: dry mouth, sweating, sexual dysfunction 4

Clinical Pearls

• Compared to other SSRIs, sertraline has less effect on the metabolism of other medications 6
• Sertraline is well-tolerated and lacks the marked anticholinergic effects of tricyclic antidepressants 4, 5
• In comparative studies, fixed-dose escitalopram 10 mg/day showed similar efficacy to flexibly-dosed sertraline (50-200 mg/day) 7

Monitoring

• Assess clinical response after 4-8 weeks of treatment 1
• Monitor for adverse effects, particularly during the initial weeks of treatment and after dose increases 4
• For long-term maintenance therapy, periodically reassess the need for continued treatment 1
