Objectives:
Patients with cancer frequently experience insomnia that significantly impacts their quality of life, worsens existing symptoms, and potentially hinders treatment outcomes and recovery. Here, we report on 3 cancer patients whose insomnia was improved with low-dose olanzapine.
Methods:
A retrospective review of medical records was conducted for 3 cancer patients experiencing insomnia treated with olanzapine at Johns Hopkins Hospital. The data collection included the type of cancer diagnosis, the level of insomnia severity experienced by individuals, and treatment results and outcome.
Results:
Olanzapine improved sleep in all 3 patients and decreased nausea/vomiting and anxiety in patients 2 and 3.
Significance Of Results:
A low dose of olanzapine has potential to treat insomnia in cancer patients. The ideal dosing regimens and potential risks are unclear, especially for long-term use. More research and clinical trials are needed to evaluate off-label use of olanzapine for insomnia, including its efficacy and risks, and to optimize the dosage to reduce its side effects in cancer patients. Oncology providers should consider olanzapine as a potential treatment for insomnia, especially given its off-label uses and potential benefits.
