What are the recommended management strategies for insomnia?

Management of Insomnia

Cognitive Behavioral Therapy for Insomnia (CBT-I) should be considered the first-line treatment for chronic insomnia due to its proven efficacy and long-term benefits with minimal side effects. 1

Non-Pharmacological Approaches

Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I is a standard of care for chronic insomnia with strong evidence supporting its effectiveness 1, 2. It includes several components:

1. Stimulus Control Therapy (Standard recommendation) 1, 2

   • Go to bed only when sleepy
   • Use bed only for sleep and sex
   • Leave bed if unable to sleep within 15-20 minutes
   • Return to bed only when sleepy
   • Maintain regular wake-up time regardless of sleep duration

2. Sleep Restriction Therapy (Guideline recommendation) 1, 2

   • Limit time in bed to match actual sleep time
   • Gradually increase time in bed as sleep efficiency improves
   • Target sleep efficiency >85%

3. Cognitive Restructuring

   • Identify and challenge negative thoughts about sleep
   • Develop realistic expectations about sleep
   • Reduce sleep-related anxiety

4. Relaxation Training (Standard recommendation) 1, 2

   • Progressive muscle relaxation
   • Deep breathing exercises
   • Meditation techniques

5. Sleep Hygiene Education (as part of multicomponent therapy)

   • Regular sleep schedule
   • Comfortable sleep environment
   • Limit caffeine, alcohol, and screen time before bed
   • Regular exercise (but not close to bedtime)
   • Use of blackout curtains, white noise machines, and earplugs 3

CBT-I has been shown to be effective in 70-80% of patients 4 and has demonstrated superior long-term effectiveness compared to pharmacological treatments 5. It is also effective for insomnia in older adults and chronic hypnotic users 2.

Pharmacological Approaches

If CBT-I is not fully effective or while waiting for CBT-I to take effect, pharmacological options may be considered:

First-Line Medications

1. Melatonin Receptor Agonists

   • Ramelteon (8mg): FDA-approved for sleep onset insomnia 6
     • Reduced latency to persistent sleep in clinical trials
     • Lower risk of complex sleep behaviors and next-day impairment
     • Minimal abuse potential
     • Safe for elderly patients 3

2. Low-Dose Doxepin (3-6mg)

   • Effective for sleep maintenance insomnia 3
   • Minimal anticholinergic effects at low doses

Second-Line Medications

1. Benzodiazepine Receptor Agonists (BzRAs)

   • Zolpidem (10mg adults, 5mg elderly): Effective for sleep onset insomnia 3, 7
   • Eszopiclone (2-3mg): Effective for sleep maintenance insomnia 3
   • Zaleplon (10mg): Short-acting, for sleep onset difficulties 3

   Important warnings:

   • Risk of complex sleep behaviors (sleep-walking, sleep-driving) 7
   • Next-day impairment affecting driving and cognitive function 7
   • Increased risk of falls, especially in elderly 7
   • Potential for dependence and withdrawal symptoms

2. Sedating Antidepressants

   • Trazodone (50-100mg): For sleep difficulties 3
   • Mirtazapine (15-30mg): Effective for both depression and sleep problems 3

Treatment Algorithm

1. Initial Assessment:

   • Evaluate for comorbid conditions (medical, psychiatric, other sleep disorders)
   • Assess insomnia pattern (onset vs. maintenance)
   • Screen for substance use that may affect sleep

2. First-Line Treatment:

   • Implement CBT-I components (stimulus control, sleep restriction, cognitive restructuring)
   • Provide sleep hygiene education

3. If inadequate response after 2-4 weeks:

   • For sleep onset insomnia: Consider ramelteon (8mg) or zaleplon (10mg)
   • For sleep maintenance insomnia: Consider low-dose doxepin (3-6mg) or eszopiclone (2-3mg)

4. Monitor response within 2-4 weeks 3

   • Assess improvement in sleep parameters
   • Evaluate for side effects
   • Adjust treatment as needed

Special Considerations

• Elderly patients:

  • Start with lower medication doses (e.g., zolpidem 5mg, mirtazapine 7.5-15mg) 3
  • Avoid benzodiazepines due to increased risk of falls and cognitive impairment 3

• Patients with comorbid conditions:

  • CBT-I is effective for insomnia comorbid with psychiatric and medical conditions 8
  • Effect sizes are larger for psychiatric than medical comorbidities 8

• Treatment goals 1:

  • Sleep onset latency <30 minutes
  • Wake after sleep onset <30 minutes
  • Total sleep time >6 hours or sleep efficiency >80-85%
  • Improvement in daytime functioning and quality of life

Common Pitfalls to Avoid

• Using too high a medication dose initially, especially in elderly patients 3
• Not allowing adequate time for CBT-I to take effect (typically requires 4-8 weeks)
• Failing to address underlying depression or anxiety while treating insomnia 3
• Long-term use of hypnotic medications without reassessment
• Neglecting to evaluate for comorbid sleep disorders like sleep apnea or restless legs syndrome 3

By following this evidence-based approach to insomnia management, clinicians can effectively address both the nighttime symptoms and daytime consequences of insomnia while minimizing potential adverse effects of treatment.
