What is the recommended tapering schedule for discontinuing sertraline (selective serotonin reuptake inhibitor) in a patient?

Sertraline Discontinuation Protocol

Sertraline should be tapered gradually rather than stopped abruptly, with dose reductions occurring over weeks to months depending on duration of use and patient tolerance, to minimize withdrawal symptoms. 1

Critical Safety Principles

• Never discontinue sertraline abruptly – the FDA label explicitly states "a gradual reduction in the dose rather than abrupt cessation is recommended whenever possible" 1
• Withdrawal symptoms can emerge after abrupt discontinuation and include dizziness, nausea, fatigue, sensory disturbances, anxiety, irritability, and flu-like symptoms 2
• These symptoms may be mistaken for relapse of depression, leading to unnecessary reinitiation of treatment 2, 3
• If intolerable symptoms occur during tapering, resume the previous dose and then decrease more gradually 1

Recommended Tapering Schedule

Standard Taper (For Most Patients)

For patients on sertraline 50-200 mg daily, reduce by 25-50 mg every 1-2 weeks: 4

• Week 1-2: Reduce from current dose by 25-50 mg (e.g., 100 mg → 75 mg or 50 mg)
• Week 3-4: Reduce by another 25-50 mg
• Continue: Reduce by 25-50 mg every 1-2 weeks until reaching 25 mg daily
• Final step: Reduce from 25 mg to discontinuation after 1-2 weeks

Hyperbolic (Non-Linear) Tapering for High-Risk Patients

For patients with risk factors for withdrawal, use smaller percentage-based reductions: 3, 5

Risk factors include: 5

• Previous withdrawal symptoms with missed doses
• Prior unsuccessful discontinuation attempts
• Treatment duration longer than 6-12 months
• Higher doses (>100 mg daily)

Hyperbolic taper reduces the biological effect at serotonin transporters in a linear manner, minimizing withdrawal: 3

• Reduce by 10-25% of the current dose (not original dose) every 2-4 weeks
• Example for 100 mg daily:
  • Weeks 1-2: 75 mg (25% reduction)
  • Weeks 3-4: 56 mg (25% of 75 mg)
  • Weeks 5-6: 42 mg (25% of 56 mg)
  • Continue pattern to very low doses (12.5 mg or less)
• Total duration: 2-6 months or longer 3, 6

Extended Taper for Long-Term Users

For patients on sertraline for years, consider tapering over 6-12 months minimum: 7, 6

• Use 10% monthly reductions of the current dose 7
• Taper to doses much lower than the therapeutic minimum (25 mg) before complete cessation 3
• The taper rate must be determined by patient tolerance, not a rigid schedule 7

Practical Implementation

Using Available Formulations

• Tablets: 25 mg, 50 mg, 100 mg tablets allow flexible dosing 1
• Oral concentrate: 20 mg/mL allows precise dose adjustments for very low doses 1
  • Must be diluted in 4 oz of water, ginger ale, lemon/lime soda, or orange juice only 1
  • Take immediately after mixing 1

Monitoring During Taper

Schedule follow-up at least monthly, more frequently during difficult phases: 7

Monitor for withdrawal symptoms at each reduction: 2, 6

• Somatic: Dizziness, nausea, fatigue, myalgia, sensory disturbances, sleep problems
• Psychological: Anxiety, irritability, crying spells, mood changes

Distinguish withdrawal from relapse: 2, 3

• Withdrawal symptoms typically emerge within days of dose reduction and are self-limiting
• Relapse develops more gradually over weeks and persists without treatment

Managing Withdrawal Symptoms

If mild symptoms occur: 2

• Reassure patient that symptoms are usually transient and self-limiting
• Continue taper at current pace if tolerable

If moderate to severe symptoms occur: 1, 2

• Return to previous dose temporarily
• Wait until symptoms stabilize (1-2 weeks)
• Resume taper with smaller dose reductions (e.g., 12.5 mg instead of 25 mg)
• Extend time between reductions to 3-4 weeks 5

Symptomatic management: 7

• Trazodone or mirtazapine for insomnia
• NSAIDs or acetaminophen for headaches and myalgia
• Antiemetics for nausea if severe

Adjunctive Psychological Support

Consider adding cognitive behavioral therapy (CBT) during the taper to increase success rates: 7, 6

• CBT significantly improves discontinuation success (40-75% successful discontinuation with psychological support vs. lower rates without) 6
• Helps distinguish withdrawal symptoms from anxiety/depression recurrence 6
• Provides coping strategies for managing symptoms during taper 7

Common Pitfalls to Avoid

• Tapering too quickly – short tapers of 2-4 weeks show minimal benefit over abrupt discontinuation 3, 6
• Using fixed timelines – adjust pace based on individual patient response, not predetermined schedule 7, 5
• Stopping at therapeutic minimum doses – taper to much lower doses (12.5 mg or less) before complete cessation 3
• Abandoning patients who struggle – maintain therapeutic relationship, consider pausing taper at stable dose 7
• Misdiagnosing withdrawal as relapse – leads to unnecessary long-term medication 3, 6

Special Populations

Adolescents

• Use same gradual tapering principles 4
• Effective doses in adolescents are generally lower than adults (20-50 mg typical therapeutic range) 4
• Monitor closely for behavioral changes during taper 4

Patients with Hepatic Impairment

• Already on lower doses; taper even more gradually 1
• Consider extending time between dose reductions to 3-4 weeks 1

When to Seek Specialist Consultation

Refer to psychiatry if: 7

• History of severe withdrawal reactions
• Multiple failed discontinuation attempts
• Unstable psychiatric comorbidities
• Concurrent substance use disorders
• Patient develops suicidal ideation during taper
