From the Research
Quetiapine should be used for the shortest duration possible, ideally 2-4 weeks, for the treatment of Hallucinogen Persisting Perception Disorder (HPPD), due to the lack of strong evidence supporting its long-term efficacy and concerns about potential side effects 1. The recommended short-term duration for using Quetiapine to treat HPPD is based on the need to balance the potential benefits of treatment with the risks of prolonged use, including metabolic effects, sedation, and potential for dependence 2, 3. Some key points to consider when using Quetiapine for HPPD include:
- Starting with the lowest effective dose, often 25-50mg at bedtime, and tapering off gradually rather than stopping abruptly 4
- Close monitoring by a psychiatrist to evaluate the effectiveness of treatment and adjust as needed 5
- Considering alternative approaches, such as lamotrigine, benzodiazepines (short-term), or non-medication therapies like CBT, for longer-term management 2, 1 It's essential to prioritize the patient's safety and well-being when using Quetiapine for HPPD, and to carefully weigh the potential benefits and risks of treatment 3, 1.
