Best Treatments for Insomnia

Cognitive Behavioral Therapy for Insomnia (CBT-I) is the first-line treatment for all adults with chronic insomnia due to its superior long-term efficacy and favorable safety profile. 1, 2

First-Line Treatment: CBT-I

• CBT-I has demonstrated superior long-term efficacy compared to pharmacological options with minimal risk of adverse effects 1

• CBT-I provides sustained benefits without risks of tolerance or adverse effects, with benefits lasting up to 2 years 3

• Key components of effective CBT-I include:

  • Stimulus control (associating bed with sleep rather than wakefulness) 1, 2
  • Sleep restriction therapy (limiting time in bed to increase sleep efficiency) 1, 2
  • Cognitive therapy (restructuring maladaptive thoughts about sleep) 1, 4
  • Sleep hygiene education (as part of comprehensive treatment) 1, 2
  • Relaxation techniques to reduce psychophysiological arousal 1, 4

• Collection of sleep diary data before and during treatment is recommended to monitor progress 1

• Various delivery methods for CBT-I are available, including in-person individual or group therapy, telephone or web-based modules, and self-help books 2

Important Note About Sleep Hygiene

• Sleep hygiene education alone is insufficient for treating chronic insomnia but should be included as part of a comprehensive treatment approach 1, 5
• Sleep hygiene involves maintaining consistent sleep schedule, creating comfortable sleep environment, limiting screen time before bed, and managing specific discomforts 6

Second-Line Treatment: Pharmacological Options

• The American College of Physicians recommends considering pharmacological therapy only when CBT-I alone is unsuccessful 2
• When medications are necessary, they should be used at the lowest effective dose for the shortest period possible (typically 4-5 weeks) 1

FDA-Approved Medications for Insomnia:

• Benzodiazepine receptor agonists (BzRAs):

  • Non-benzodiazepines (Z-drugs): zaleplon, zolpidem, and eszopiclone 2
  • Zolpidem has been shown to decrease sleep latency for up to 35 days in controlled clinical studies 7
  • Eszopiclone has demonstrated decreased sleep latency and improved sleep maintenance in studies up to 6 months 8
  • Traditional benzodiazepines: triazolam, estazolam, temazepam, flurazepam, and quazepam 2

• Other FDA-approved options:

  • Orexin receptor antagonist (suvorexant) 2
  • Melatonin receptor agonist (ramelteon) - particularly for sleep onset difficulties 2, 3
  • Low-dose doxepin (3-6 mg) - particularly effective for sleep maintenance insomnia 1, 3

Potential Adverse Effects of Medications:

• BzRAs can cause residual sedation, daytime impairment, memory issues, increased risk of falls, and behavioral abnormalities including "sleep driving" 1, 7
• Anterograde amnesia has been reported with zolpidem, predominantly at doses above 10 mg 7
• Benzodiazepines should be avoided in patients with substance use history due to high abuse potential 1

Treatment Algorithm

1. Start with CBT-I as first-line treatment 1, 2

   • Implement all components (stimulus control, sleep restriction, cognitive therapy, etc.)
   • Continue for at least 4-8 weeks to evaluate effectiveness

2. If CBT-I is insufficient after adequate trial, consider pharmacological options 2, 1

   • Select medication based on:
     • Symptom pattern (sleep onset vs. maintenance difficulties)
     • Patient characteristics (age, comorbidities)
     • Previous treatment response
     • Risk of abuse/dependence
     • Cost and patient preference

3. When using medications: 1, 2

   • Start with lowest effective dose
   • Limit duration to 4-5 weeks when possible
   • Continue incorporating behavioral techniques
   • Monitor regularly for treatment response, adverse effects, and potential misuse

Common Pitfalls to Avoid

• Using medications as first-line treatment instead of CBT-I 1, 2
• Relying solely on sleep hygiene education without other CBT-I components 5, 1
• Using antihistamine sleep aids or herbal substances like valerian, which lack sufficient efficacy and safety data 1
• Failing to screen for underlying medical or psychiatric conditions that may be causing or worsening insomnia 9, 10
• Long-term use of hypnotic medications without regular reassessment of need and effectiveness 1, 9
