From the Research

Several medications, including selective serotonin reuptake inhibitors (SSRIs), lamotrigine, clonazepam, naltrexone, and atypical antipsychotics, may be potentially useful in treating depersonalization disorder, though none are FDA-approved specifically for this condition. When considering treatment options, it's essential to prioritize medications that have shown promise in recent studies. According to the most recent study 1, a series of treatments, such as pharmacotherapies, neuromodulation, and psychotherapies, could be considered in combination. Some key medications that may be considered include:

  • SSRIs like fluoxetine (20-80 mg daily), sertraline (50-200 mg daily), or escitalopram (10-20 mg daily), which are often tried first, particularly when depersonalization co-occurs with anxiety or depression
  • Lamotrigine, an anticonvulsant, which has shown promise at doses of 25-300 mg daily, typically starting at 25 mg and gradually increasing
  • Clonazepam, a benzodiazepine, which may be helpful at 0.5-2 mg daily, especially for acute episodes, though it carries risks of dependence and is generally used short-term
  • Naltrexone, an opioid antagonist, which has been used at doses of 25-100 mg daily based on the theory that endogenous opioid systems may play a role in depersonalization symptoms
  • Atypical antipsychotics like aripiprazole (2-15 mg daily) or olanzapine (2.5-10 mg daily), which are sometimes used as augmentation strategies for treatment-resistant cases. It's also important to note that treatment typically requires 4-8 weeks to assess effectiveness, and combining medication with psychotherapy, particularly cognitive-behavioral therapy, often yields better results than medication alone, as suggested by studies 2, 3, 4. These medications work by modulating neurotransmitter systems involved in perception, emotion regulation, and stress response, which may be dysregulated in depersonalization. However, it's crucial to consider the limitations of current research, as highlighted by studies 5, 4, which emphasize the need for more rigorous and high-quality studies to establish effective treatment guidelines for depersonalization disorder.
