Management of Difficulty Sleeping
First-Line Treatment: Cognitive Behavioral Therapy for Insomnia (CBT-I)
Cognitive Behavioral Therapy for Insomnia (CBT-I) must be initiated as the primary treatment for all patients with chronic insomnia before considering any pharmacological intervention, as it demonstrates superior long-term efficacy with sustained benefits after discontinuation. 1, 2
Core Components of CBT-I
Stimulus control therapy involves going to bed only when sleepy, leaving bed if unable to sleep within 20 minutes, using the bedroom exclusively for sleep and sex, and maintaining a consistent sleep-wake schedule to strengthen the association between bed and sleep 1, 3
Sleep restriction therapy requires calculating mean total sleep time from 1-2 week sleep logs, setting time in bed to match actual sleep time (not less than 5 hours), and adjusting weekly based on sleep efficiency (target >85%) to consolidate sleep and improve quality 1
Cognitive restructuring addresses maladaptive beliefs such as "I can't sleep without medication" or "My life will be ruined if I can't sleep" that perpetuate insomnia 1
Relaxation training including progressive muscle relaxation, guided imagery, or diaphragmatic breathing reduces somatic and cognitive arousal 1, 3
Sleep Hygiene Education (Adjunctive Only)
Sleep hygiene alone is insufficient as monotherapy but should be incorporated into CBT-I 1, 2:
- Maintain a regular sleep-wake schedule, even on weekends 1
- Avoid caffeine after noon and limit alcohol consumption 1
- Keep the bedroom dark, cool (around 65-68°F), and quiet 1
- Avoid heavy meals within 2-3 hours of bedtime 1
- Engage in regular morning or afternoon exercise, but avoid vigorous exercise within 2 hours of bedtime 1
CBT-I Delivery Formats
CBT-I can be effectively delivered through individual therapy, group sessions, telephone-based programs, web-based modules, or self-help books—all formats demonstrate effectiveness 2, 4
Environmental Optimization for ICU Patients
For critically ill patients with sleep disruption, implement a multicomponent protocol that optimizes the environment by controlling light and noise, clustering care activities, and protecting sleep cycles during the 2-4 AM or 12-5 AM periods when uninterrupted sleep is most likely to occur. 5
- Turn down lights and reduce ambient noise during designated quiet periods 5
- Cluster patient care activities to avoid routine procedures (such as daily baths) during protected sleep periods 5
- Implement scheduled rest periods, with 2-4 AM being the most consistently uninterrupted time in ICU settings 5
- This multicomponent approach may reduce delirium prevalence (RR 0.62,95% CI 0.42-0.91) 5
Second-Line: Pharmacological Treatment
Pharmacological options should only be considered after 4-8 weeks of unsuccessful behavioral interventions, using the lowest effective dose for the shortest duration possible. 1, 2
First-Line Pharmacotherapy Options
For sleep onset insomnia:
- Zaleplon 10 mg (5 mg in elderly) 2
- Ramelteon 8 mg (melatonin receptor agonist with minimal abuse potential) 2
- Zolpidem 10 mg (5 mg maximum in elderly and women) 2
For sleep maintenance insomnia:
- Low-dose doxepin 3-6 mg (reduces wake after sleep onset by 22-23 minutes with moderate-quality evidence) 2
- Suvorexant (orexin receptor antagonist) 2
- Eszopiclone 2-3 mg 2
For both sleep onset and maintenance:
Critical Medications to AVOID
Do NOT use the following agents due to unfavorable risk-benefit profiles:
Over-the-counter antihistamines (diphenhydramine, hydroxyzine) cause anticholinergic effects, daytime sedation, delirium risk in elderly, and may accelerate dementia progression 1, 3, 2
Trazodone is explicitly NOT recommended by the American Academy of Sleep Medicine for sleep onset or maintenance insomnia, as trials show modest improvements in sleep parameters but no improvement in subjective sleep quality, with harms outweighing benefits 2
Long-acting benzodiazepines (diazepam, lorazepam) carry increased risks of falls, cognitive impairment, dependence, and associations with dementia without clear benefit over shorter-acting alternatives 3, 2
Herbal supplements (valerian) and nutritional substances (melatonin) lack sufficient evidence of efficacy 2
Special Population Considerations
Elderly Patients (Age 65+)
Use extreme caution with benzodiazepines due to high fall risk, cognitive impairment, and dependence; taper and discontinue if currently prescribed 1, 3
Reduce all sedative medication doses by at least 50%: zolpidem maximum 5 mg, zaleplon 5 mg, eszopiclone 1-2 mg 1, 3, 2
Screen for sleep apnea and restless legs syndrome, as these conditions are common in elderly populations and may present as insomnia 1
Safest pharmacological choices for elderly include ramelteon 8 mg or low-dose doxepin 3 mg due to minimal fall risk and cognitive impairment 2
Patients with Comorbid Depression/Anxiety
Sedating antidepressants should be the preferred initial pharmacological choice when comorbid depression/anxiety exists, as they simultaneously address both conditions 2
Mirtazapine or other sedating antidepressants require nightly scheduled dosing (not PRN) due to 20-40 hour half-life and need for steady-state levels 2
Avoid antidepressants with high anticholinergic burden (amitriptyline, tricyclics) in elderly patients with potential cognitive decline 3
ICU Patients
Prioritize nonpharmacologic interventions including environmental optimization, light/noise control, and care clustering during 2-4 AM protected sleep periods 5, 1
One study included pharmacologic guidelines administering zolpidem to patients without delirium and haloperidol or atypical antipsychotics for patients with delirium as part of a multicomponent protocol 5
Critical Safety Warnings
Dependence and Withdrawal
All benzodiazepines and benzodiazepine receptor agonists carry risk of physical dependence with prolonged use; abrupt discontinuation can precipitate life-threatening withdrawal reactions including seizures. 6
- Use gradual taper with patient-specific plan when discontinuing 6
- Patients at highest risk: those on higher doses and longer duration of use 6
- Protracted withdrawal syndrome can last weeks to more than 12 months 6
Complex Sleep Behaviors
All sedative-hypnotics may cause complex behaviors including sleep-driving, sleep-walking, preparing food, making phone calls, or having sex while not fully awake, with amnesia for the event 2, 6
Discontinue medication immediately if patient reports sleep-driving or other complex behaviors 6
Risk increases with alcohol/CNS depressant co-administration and doses exceeding maximum recommended 6
Severe Anaphylactic Reactions
- Rare cases of angioedema involving tongue, glottis, or larynx have been reported after first or subsequent doses 6
- Patients who develop angioedema should never be rechallenged with the drug 6
Treatment Algorithm
Initiate CBT-I immediately for all patients with chronic insomnia (sleep difficulty ≥3 nights/week for ≥1 month) 1, 2
Optimize sleep environment and implement sleep hygiene measures as adjunct to CBT-I 1
Assess for underlying conditions: If insomnia persists beyond 7-10 days of treatment, evaluate for sleep apnea, restless legs syndrome, circadian rhythm disorders, psychiatric conditions, or medication-induced causes 2, 6
Consider pharmacotherapy only after 4-8 weeks of unsuccessful CBT-I, selecting agent based on:
Continue CBT-I alongside any pharmacotherapy, as behavioral interventions provide more sustained effects and facilitate medication discontinuation 2
Reassess after 1-2 weeks to evaluate efficacy on sleep latency, maintenance, daytime functioning, and monitor for adverse effects including morning sedation, cognitive impairment, and complex sleep behaviors 2
Use lowest effective dose for shortest duration, with intermittent dosing (3 nights/week) or as-needed administration when appropriate rather than nightly chronic use 2
Common Pitfalls to Avoid
Failing to implement CBT-I before or alongside pharmacotherapy—behavioral interventions are the standard of care with superior long-term outcomes 1, 2
Using sleep hygiene education alone—it must be combined with other CBT-I components (stimulus control, sleep restriction, cognitive restructuring) to be effective 1, 2
Prescribing over-the-counter antihistamines or trazodone—these agents lack efficacy data and carry significant risks, particularly in elderly patients 1, 3, 2
Using standard adult doses in elderly patients—all sedative-hypnotics require dose reduction by at least 50% in patients age 65+ 1, 3, 2
Continuing pharmacotherapy long-term without periodic reassessment—regular follow-up is essential to evaluate ongoing need and monitor for adverse effects 2
Abrupt discontinuation of benzodiazepines or benzodiazepine receptor agonists—always use gradual taper to prevent withdrawal seizures 6
Overlooking medication-induced insomnia—SSRIs, β-blockers, bronchodilators, corticosteroids, decongestants, and diuretics commonly cause or worsen sleep disturbance 3
