What are the recommended treatment options for a patient with insomnia, considering their medical history and potential underlying conditions?

Treatment for Insomnia

Cognitive Behavioral Therapy for Insomnia (CBT-I) is the first-line treatment for all adults with chronic insomnia and must be initiated before or alongside any pharmacological intervention. 1, 2, 3

Initial Treatment Approach

CBT-I as Standard of Care

• CBT-I demonstrates superior long-term efficacy compared to medications, with sustained benefits for up to 2 years after treatment discontinuation and no risk of tolerance, dependence, or adverse effects. 1, 3, 4

• CBT-I must include these core behavioral and cognitive components: 1, 3, 5

  • Sleep restriction therapy: Limits time in bed to match actual sleep duration, creating mild sleep deprivation that strengthens homeostatic sleep drive and consolidates sleep 3
  • Stimulus control therapy: Re-establishes the bed as a cue for sleep rather than wakefulness through specific instructions (e.g., go to bed only when sleepy, get out of bed if unable to sleep within 15-20 minutes, use bed only for sleep and sex) 1, 3
  • Cognitive therapy: Targets maladaptive thoughts and beliefs about sleep using structured psychoeducation, Socratic questioning, and behavioral experiments 3
  • Relaxation techniques: Progressive muscle relaxation, guided imagery, or breathing exercises 6, 5
  • Sleep hygiene education: Addresses environmental and behavioral factors, though insufficient as monotherapy 6, 3

• CBT-I can be delivered through multiple accessible formats—all demonstrating effectiveness: individual therapy, group sessions, telephone-based programs, web-based modules, or self-help books. 1, 2

Sleep Hygiene Components (Adjunct Only)

Sleep hygiene education alone is insufficient as monotherapy but should be included as part of comprehensive treatment: 6, 1

• Wake up at the same time every day and maintain a consistent bedtime 6
• Exercise regularly but not within 2-4 hours of bedtime 6
• Avoid caffeine and nicotine for at least 6 hours before bedtime 6
• Drink alcohol only in moderation and avoid use for at least 4 hours before bedtime 6
• Keep the bedroom quiet and temperature regulated 6
• Avoid napping and excess fluid intake before bedtime 6

Pharmacological Treatment

When to Consider Medications

Pharmacotherapy should only be added if CBT-I is insufficient, unavailable, or while CBT-I is being implemented—medications must supplement, not replace, behavioral interventions. 1, 2, 3

First-Line Pharmacotherapy Options

The American Academy of Sleep Medicine recommends short-intermediate acting benzodiazepine receptor agonists (BzRAs) or ramelteon as first-line medications: 1

For sleep onset insomnia: 1

• Zaleplon 10 mg (5 mg in elderly) 1
• Zolpidem 10 mg (5 mg in elderly—FDA-mandated lower dose due to cognitive and behavioral changes) 1
• Ramelteon 8 mg (melatonin receptor agonist with different mechanism, no abuse potential) 1, 7
• Triazolam 0.25 mg (associated with rebound anxiety, not preferred) 1

For sleep maintenance insomnia: 1

• Eszopiclone 2-3 mg (effective for both sleep onset and maintenance) 1
• Zolpidem 10 mg (5 mg in elderly) 1
• Temazepam 15 mg 1
• Suvorexant (orexin receptor antagonist) 1, 8
• Low-dose doxepin 3-6 mg (reduces wake after sleep onset by 22-23 minutes with moderate-quality evidence) 1

Second-Line Options

• Sedating antidepressants (mirtazapine, low-dose doxepin) are preferred when comorbid depression or anxiety is present 1
• Lemborexant and other newer orexin receptor antagonists offer advantages over older agents with lower risk of cognitive and psychomotor effects 1

Medications NOT Recommended

The American Academy of Sleep Medicine explicitly recommends against: 1, 3

• Over-the-counter antihistamines (e.g., diphenhydramine) due to lack of efficacy data, daytime sedation, and delirium risk, especially in elderly patients 1, 2
• Trazodone for sleep onset or maintenance insomnia (harms outweigh benefits) 1
• Herbal supplements (e.g., valerian) and melatonin due to insufficient evidence of efficacy 1, 3
• Tiagabine (anticonvulsant) 1
• Older hypnotics including barbiturates and chloral hydrate 1
• Long-acting benzodiazepines (e.g., diazepam, clonazepam as first-line) due to increased risks without clear benefit, including prolonged daytime sedation, cognitive impairment, falls, and fractures 1, 2

Treatment Algorithm

1. Initiate CBT-I immediately through the most accessible format (individual, group, telephone, web-based, or self-help) 1, 2, 3

2. Implement comprehensive sleep hygiene as part of CBT-I, not as standalone treatment 6, 1

3. If CBT-I insufficient after 4-6 weeks, add pharmacotherapy based on symptom pattern: 1

   • Sleep onset difficulty → zaleplon, ramelteon, or zolpidem
   • Sleep maintenance → eszopiclone, temazepam, doxepin, or suvorexant
   • Both onset and maintenance → eszopiclone or zolpidem

4. If first-line medication unsuccessful, try alternative agent in same class before moving to second-line options 1

5. If comorbid depression/anxiety present, consider sedating antidepressants (mirtazapine, low-dose doxepin) 1

6. Use lowest effective dose for shortest duration possible, typically less than 4 weeks for acute insomnia 1, 2

7. Monitor regularly during initial treatment period to assess effectiveness, side effects, and ongoing medication need 1

8. Taper medication when conditions allow, with CBT-I facilitating successful discontinuation 1

Special Population Considerations

Elderly Patients (Age 65+)

• Maximum zolpidem dose 5 mg (not 10 mg) due to increased sensitivity and fall risk 1
• Ramelteon 8 mg or low-dose doxepin 3 mg are safest choices due to minimal fall risk and cognitive impairment 1
• Higher risk of complex sleep behaviors (sleep-driving, sleep-walking), falls, fractures, and cognitive impairment with all hypnotics 1

Pregnant Women

• CBT-I remains first-line treatment with favorable benefit-to-risk ratio without medication exposure 2
• Pharmacotherapy only if CBT-I insufficient, unavailable, or while being implemented 2
• Ramelteon 8 mg may be considered for sleep onset insomnia despite limited pregnancy-specific data 2
• Avoid long-acting benzodiazepines (risk of prolonged neonatal sedation) and antipsychotics 2

Patients with Comorbid Conditions

• Comorbid depression/anxiety: Sedating antidepressants (mirtazapine, low-dose doxepin) address both mood disorder and sleep disturbance simultaneously 1
• History of substance abuse: Avoid benzodiazepines; consider ramelteon or suvorexant 1
• Seizure disorder or bipolar disorder: Use caution with sleep restriction therapy due to sleep deprivation effects 1

Critical Safety Considerations

All Hypnotics Carry Risks

• Complex sleep behaviors (sleep-driving, sleep-walking, sleep-eating) may occur—stop medication immediately if patient discovers they performed activities while not fully awake 1
• Driving impairment and motor vehicle accidents documented by FDA for all benzodiazepine and nonbenzodiazepine hypnotics 1
• Falls, fractures, cognitive impairment, particularly in elderly patients 1
• Observational studies suggest associations with dementia, fractures, and major injuries (primarily from benzodiazepine studies) 1

Medication-Specific Warnings

• Benzodiazepines: Risk of dependence, withdrawal reactions, cognitive impairment; require careful tapering upon discontinuation 1
• FDA mandates lower doses in women and older adults due to cognitive and behavioral changes 1
• Hepatic impairment: Zaleplon dose should be reduced to 5 mg (clearance reduced by 70-87% in cirrhosis) 1

Common Pitfalls to Avoid

• Starting with medications before attempting CBT-I violates guideline recommendations and deprives patients of more effective, durable therapy 1, 2, 3
• Relying on sleep hygiene education alone lacks efficacy as single intervention and must be combined with other CBT-I components 1, 2
• Using sedating agents without considering specific effects on sleep onset versus maintenance 1
• Failing to consider drug interactions and contraindications 1
• Continuing pharmacotherapy long-term without periodic reassessment 1
• Using doses appropriate for younger adults in elderly patients (e.g., zolpidem requires age-adjusted dosing to maximum 5 mg) 1
• Combining multiple sedative medications significantly increases risks of complex sleep behaviors, cognitive impairment, falls, and fractures 1

Assessment Requirements

Before initiating treatment, assess: 6

• Sleep history using 2-week sleep diary (minimum) documenting sleep quality, sleep parameters, napping, daytime impairment, medications, activities, evening meal timing, caffeine/alcohol consumption, and stress level 6
• Underlying causes and comorbidities: recent stressors, detailed history, drug history 6
• Screen for other sleep disorders (sleep apnea, restless legs syndrome, circadian rhythm disorders) if insomnia persists beyond 7-10 days of treatment 1
• Impact on quality of life, daytime functioning, ability to drive, employment, relationships, and mood 6
• Patient beliefs about sleep 6
