From the Guidelines

For patients with obesity who need sleep medication, I recommend starting with non-benzodiazepine medications like zolpidem (Ambien) 5mg, eszopiclone (Lunesta) 1-2mg, or zaleplon (Sonata) 5mg at bedtime, as they have less respiratory depression risk than benzodiazepines, which is important since obesity increases the risk of sleep apnea, as noted in the 2019 U.S. Department of Veterans Affairs and U.S. Department of Defense clinical practice guidelines 1.

Key Considerations

  • Non-benzodiazepine medications should be administered at the lowest effective dose and for the shortest possible duration to minimize the incidence of adverse events, as recommended by the guidelines 1.
  • Melatonin 1-3mg or ramelteon (Rozerem) 8mg are even safer alternatives with minimal side effects and can be considered as first-line treatment options.
  • Antihistamines like diphenhydramine should be avoided for long-term use as they can cause weight gain and have antimuscarinic adverse effects, particularly in older adults 1.
  • Antipsychotics, such as quetiapine, should not be used to treat insomnia disorder due to their unclear efficacy and potential harms, including increased risk for death in elderly populations with dementia-related psychosis and increased suicidal tendencies in children, adolescents, and young adults 1.

Behavioral Changes and Weight Management

  • Implementing behavioral changes like consistent sleep schedules, limiting screen time before bed, and creating a cool, dark sleeping environment is crucial for improving sleep quality.
  • Weight management strategies should be pursued simultaneously, as weight loss can significantly improve sleep quality by reducing sleep apnea symptoms and decreasing inflammatory markers that disrupt sleep.
  • Patients with obesity should be screened for obstructive sleep apnea before starting any sleep medication, as untreated sleep apnea may require CPAP therapy rather than medication.

From the FDA Drug Label

The FDA drug label does not answer the question.

From the Research

Sleep Medication and Obesity

  • There is no direct evidence in the provided studies that links sleep medication with obesity.
  • However, study 2 discusses the relationship between sleep disorders and obesity, stating that sleep disorders are one of the pathologies triggered by obesity.
  • Study 3 examines the efficacy and side effects of zolpidem, a sleep medication, but does not mention its relationship with obesity.
  • Studies 4, 5, and 6 focus on the treatment of insomnia, including non-pharmacological approaches, but do not discuss the link between sleep medication and obesity.

Non-Pharmacological Approaches to Insomnia

  • Studies 2, 5, and 6 emphasize the importance of non-pharmacological approaches in managing insomnia and obesity.
  • These approaches include cognitive behavioral therapy for insomnia (CBT-I), exercise, relaxation techniques, and complementary alternative medicine.
  • Study 6 provides an overview of current recommendations and up-to-date evidence for the non-pharmacological treatment of insomnia, highlighting the importance of CBT-I and other non-pharmacological approaches.

Treatment of Insomnia

  • Study 4 evaluates the literature on the treatment of chronic insomnia disorder in menopause, suggesting cognitive-behavioral therapy for insomnia, hormone therapy, and other interventions.
  • Study 3 discusses the use of zolpidem as a pharmacological treatment for insomnia, highlighting its efficacy and potential side effects.
  • Studies 5 and 6 focus on non-pharmacological approaches to insomnia, emphasizing the importance of CBT-I and other non-pharmacological interventions.
