Tapering Sertraline 25 mg Daily
For an adult stable on sertraline 25 mg daily, taper by reducing to 12.5 mg (half-tablet) daily for 1–2 weeks, then discontinue. 1
Standard Tapering Protocol
The minimum taper duration for sertraline is 2–4 weeks for patients on short-term therapy. 1 Since 25 mg is already a low dose—below the standard therapeutic range of 50–200 mg/day—a brief taper is appropriate. 1
Recommended Schedule
- Week 1–2: Reduce to 12.5 mg daily (cut 25 mg tablet in half)
- Week 3: Discontinue completely
For patients who have been on sertraline for longer than 4–12 months, extend the taper over several weeks to months rather than rushing discontinuation. 1 In such cases, consider:
- Week 1–2: 12.5 mg daily
- Week 3–4: 12.5 mg every other day
- Week 5: Discontinue
Managing Withdrawal Symptoms
Sertraline is associated with discontinuation syndrome characterized by dizziness, fatigue, myalgias, headaches, nausea, insomnia, and sensory disturbances. 1 These symptoms typically emerge within 1–2 days after dose reduction due to sertraline's 22–36 hour elimination half-life. 2, 3
If moderate to severe withdrawal symptoms occur, reinstitute the previous dose and hold at that level for an additional 1–2 weeks before attempting further reduction. 1 Common withdrawal symptoms include:
- Dizziness and light-headedness 4
- Nausea and vomiting 4
- Fatigue, lethargy, myalgia 4
- Sensory disturbances ("brain zaps") 4
- Anxiety, irritability, crying spells 4
The taper rate must be determined by the patient's tolerance, not a rigid schedule. 1 Some patients may require slower tapers with 10% reductions of the current dose at each step. 1
Monitoring Requirements
Monitor closely during taper for:
- Emergence of withdrawal symptoms at each dose reduction 1
- Return of original psychiatric symptoms (depression, anxiety) 1
- Suicidal ideation, particularly in younger patients 1
Follow up at least every 1–2 weeks during the taper, with more frequent contact if withdrawal symptoms emerge. 1
Patient Education
Before initiating the taper, establish a collaborative plan that includes:
- Clear explanation of why gradual tapering is necessary 1
- Discussion of potential withdrawal symptoms 1
- Agreement on the taper schedule 1
- Reassurance that withdrawal symptoms are usually transient and self-limiting 4
Educate the patient that withdrawal symptoms may be mistaken for relapse into depression, which could lead to unnecessary resumption of medication. 4
Special Considerations
For patients with hepatic disease, use extra caution and consider an even slower taper, as sertraline undergoes extensive first-pass hepatic metabolism. 1, 2
No dose adjustment is needed for renal impairment, as sertraline metabolites are primarily excreted renally as conjugates. 1, 2
For elderly patients (≥60 years), the standard taper applies, as sertraline has minimal anticholinergic effects and no age-based dose adjustment is required. 1, 5
Critical Pitfalls to Avoid
- Never stop sertraline abruptly—always taper gradually over a minimum of 2–4 weeks 1, 4
- Do not accelerate the taper if withdrawal symptoms emerge—instead, pause or slow the reduction 1
- Do not mistake withdrawal symptoms for relapse—withdrawal is typically characterized by physical symptoms (dizziness, nausea, sensory disturbances) rather than purely psychological symptoms 4
- Do not abandon the patient if tapering is difficult—some individuals may require extended tapers lasting several months 1
When Extended Tapers Are Necessary
Extended tapers of several months may be necessary for:
- Patients on long-term treatment (>1 year) 1
- Those experiencing withdrawal symptoms even at low doses 1
- High-risk patients with history of severe withdrawal or comorbid anxiety 1
In such cases, consider hyperbolic tapering to very low doses (e.g., 6.25 mg, 3 mg) before complete discontinuation, as PET imaging data suggest this reduces serotonin transporter occupancy in a more linear manner and minimizes withdrawal. 6
