Quetiapine Discontinuation Guidelines

Introduction to Tapering

The Centers for Disease Control and Prevention, as reflected in MMWR Recommendations and Reports, suggests beginning with a 10% dose reduction per week as a conservative starting point, adjusting based on patient tolerance 1
For patients who have been taking quetiapine for extended periods, the Mayo Clinic Proceedings recommends implementing even slower tapers of 10% per month or slower to reduce the risk of severe withdrawal symptoms 3

The MMWR Recommendations and Reports guidelines recommend reducing the dose by 10% of the original dose at each step, creating progressively smaller absolute reductions as lower doses are approached 1
Once the smallest available dose is reached, the MMWR Recommendations and Reports suggest extending the interval between doses rather than splitting tablets 1
Discontinuation should be considered complete when dosing frequency is less than once daily, as per the MMWR Recommendations and Reports 1

The Praxis Medical Insights guidelines suggest scheduling more frequent follow-up appointments during the tapering period to monitor for withdrawal symptoms and provide support 2
The Mayo Clinic Proceedings recommends using standardized symptom rating scales to distinguish withdrawal symptoms from relapse of the underlying psychiatric condition 3

If severe symptoms develop, the MMWR Recommendations and Reports suggest reinstituting the previous well-tolerated dose immediately and slowing the taper rate further 1
The Mayo Clinic Proceedings notes that some symptoms, particularly anxiety and mood changes, may persist for weeks to months after complete discontinuation, a phenomenon known as "protracted withdrawal" 3

The MMWR Recommendations and Reports guidelines recommend exercising extreme caution when tapering quetiapine during pregnancy, as withdrawal may pose risks to both mother and fetus 1
The MMWR Recommendations and Reports suggest that if a patient cannot tolerate tapering despite multiple attempts, consideration should be given to pausing the taper and restarting when the patient is ready 1
