Escitalopram Discontinuation: Gradual Tapering Required

Escitalopram should be gradually tapered when discontinuing rather than stopped abruptly to prevent withdrawal symptoms. 1

Why Tapering is Necessary

Abrupt discontinuation of escitalopram can lead to significant withdrawal symptoms, including:

• Dysphoric mood, irritability, agitation
• Dizziness (44% of patients) 2
• Sensory disturbances (paresthesias, electric shock sensations)
• Anxiety, confusion, headache
• Muscle tension (44%) 2
• Chills (44%) 2
• Confusion or trouble concentrating (40%) 2
• Emotional lability, insomnia
• Amnesia (28%) 2

The FDA drug label explicitly states that "a gradual reduction in the dose rather than abrupt cessation is recommended whenever possible" 1. While some withdrawal symptoms are self-limiting, there have been reports of serious discontinuation symptoms that require medical attention.

Risk Factors for Withdrawal Symptoms

Research indicates that certain factors increase the risk of experiencing withdrawal symptoms:

• Higher treatment doses of escitalopram 2
• Higher plasma concentrations 2
• Longer duration of treatment (especially beyond 14 days) 3

A study found that patients with escitalopram discontinuation syndrome had significantly higher treatment doses and plasma concentrations compared to those who didn't experience withdrawal 2.

Recommended Tapering Protocol

The optimal tapering schedule depends on:

1. Duration of treatment:

   • Less than 7 days: Can usually be discontinued quickly with minimal risk 3
   • 7-14 days: May need tapering but can be weaned more quickly 3
   • More than 14 days: Requires a more gradual tapering protocol 3

2. Current dose:

   • Higher doses require more gradual tapering 2

3. Recommended approach:

   • Reduce by 10-20% of the original dose every 24-48 hours 3
   • For patients on higher doses or with longer treatment duration, "very slow tapering is recommended" 2

Monitoring During Tapering

During the tapering process:

• Monitor for withdrawal symptoms
• If severe symptoms occur, consider temporarily returning to the previous dose before continuing with a more gradual taper 1
• If intolerable symptoms occur following a decrease in dose, resuming the previously prescribed dose may be considered before continuing with a more gradual reduction 1

Special Considerations

• Elderly patients: May be more sensitive to discontinuation effects and may require even more gradual tapering
• Patients with history of withdrawal symptoms: May benefit from an especially slow taper
• Patients with anxiety disorders: May experience rebound anxiety during tapering

Conclusion

The evidence clearly demonstrates that escitalopram should not be stopped abruptly. A gradual, individualized tapering schedule is essential to minimize withdrawal symptoms and ensure patient comfort and safety. The most recent and highest quality evidence suggests that very slow tapering is the safest approach, especially for patients who have been on higher doses or longer treatment durations 2.
