Mirtazapine Tapering Protocol

Recommended Tapering Schedule

• The Centers for Disease Control and Prevention, as reported in MMWR Recommendations and Reports, recommends reducing the mirtazapine dose by 10% of the current dose every 1-2 weeks as a reasonable starting point, though slower tapers are often better tolerated, particularly for patients on long-term therapy 1, 2
• Each new dose should be 90% of the previous dose, not a straight-line reduction from the original starting dose, to prevent disproportionately large reductions at lower doses, as suggested by Praxis Medical Insights 3

Managing Withdrawal Symptoms

• If withdrawal symptoms become severe, temporarily return to the previous dose and then resume tapering at a slower rate, according to Praxis Medical Insights 3
• The taper rate must be determined by the patient's ability to tolerate reductions, not by a rigid schedule, as recommended by Praxis Medical Insights 2
• Pauses in the taper are acceptable and often necessary when withdrawal symptoms emerge, as suggested by Praxis Medical Insights 2

Monitoring Requirements

• Follow up at least monthly during the taper, with more frequent contact needed during difficult phases, as recommended by Praxis Medical Insights 2
• Monitor for withdrawal symptoms including anxiety, insomnia, mood changes, and panic symptoms, according to Praxis Medical Insights 2
• Advise patients of increased overdose risk if they return to previous doses after tolerance is lost, as recommended by Praxis Medical Insights 2

Important Clinical Considerations

• Once the smallest available dose is reached, the interval between doses can be extended before complete cessation, as suggested by MMWR Recommendations and Reports 1
• If the patient is also taking benzodiazepines, address the benzodiazepine taper first due to the higher risks associated with benzodiazepine withdrawal, as recommended by Praxis Medical Insights 2, 3
• Benzodiazepine withdrawal carries greater risks than antidepressant withdrawal and should take precedence, according to Praxis Medical Insights 2

Common Pitfalls to Avoid

• Do not use rigid tapering schedules that ignore patient tolerance—the taper must be individualized based on symptom emergence, as recommended by Praxis Medical Insights 2
