How should I stop a 10 mg daily dose of Celexa (citalopram)?

How to Discontinue Celexa 10 mg Daily

Gradually taper Celexa by reducing the dose rather than stopping abruptly, as discontinuation syndrome is well-documented with citalopram and can cause significant withdrawal symptoms. 1

Tapering Strategy

The FDA-approved prescribing information explicitly recommends gradual dose reduction rather than abrupt cessation whenever possible. 1 If intolerable symptoms occur following a dose decrease or upon discontinuation, resuming the previously prescribed dose should be considered, followed by a more gradual taper. 1

Specific Tapering Approach for 10 mg Daily

• Reduce to 5 mg daily for at least 1-2 weeks before complete discontinuation 2
• The American Academy of Child and Adolescent Psychiatry guidelines note that dose adjustments for shorter half-life SSRIs like citalopram should occur at approximately 1-2 week intervals 2
• Do NOT use alternate-day dosing (every other day) as a tapering strategy, as recent evidence demonstrates this approach causes pronounced receptor occupancy variation and significantly increases withdrawal symptom risk 3

Expected Discontinuation Syndrome Symptoms

Citalopram discontinuation syndrome can include: 2

• Dizziness, fatigue, lethargy, general malaise
• Myalgias, chills, headaches
• Nausea, vomiting, diarrhea
• Insomnia, imbalance, vertigo
• Sensory disturbances, paresthesias
• Anxiety, irritability, agitation
• In rare cases, sustained hypertension has been reported with abrupt citalopram cessation 4

Important Clinical Considerations

Monitor patients closely for withdrawal symptoms when discontinuing treatment. 1 The discontinuation syndrome has been reported following missed doses or acute discontinuation of shorter-acting SSRIs, with citalopram specifically mentioned as having this risk (though to a lesser extent than paroxetine). 2

Common Pitfalls to Avoid

• Never recommend alternate-day dosing: This creates dangerous fluctuations in drug levels and receptor occupancy, substantially increasing withdrawal risk even at low doses 3
• Do not taper too quickly: A gradual reduction over several weeks minimizes rebound effects 5
• Consider the clinical context: If the patient is being treated for depression or anxiety, ensure appropriate follow-up to monitor for symptom recurrence versus withdrawal symptoms 1

If Withdrawal Symptoms Occur

• Resume the previous dose (5 mg or 10 mg) that was tolerated 1
• Once symptoms resolve, attempt an even slower taper
• Consider extending the time between dose reductions to 2-3 weeks or longer 5
