Management of Chronic Insomnia
Cognitive Behavioral Therapy for Insomnia (CBT-I) should be the first-line treatment for all adults with chronic insomnia due to its superior long-term efficacy and safety profile compared to pharmacological options. 1, 2
First-Line Treatment: CBT-I
- CBT-I is recommended as the initial treatment for chronic insomnia by the American College of Physicians, American Academy of Sleep Medicine, and VA/DoD with moderate-quality evidence supporting its effectiveness 1, 2
- CBT-I produces reliable and durable improvements in sleep parameters that are sustained for at least 6 months after treatment completion 3, 4
- 70-80% of patients treated with nonpharmacological interventions benefit from treatment 4
Key Components of CBT-I
Stimulus control therapy (Standard): Designed to extinguish negative associations between bed and wakefulness 1
- Go to bed only when sleepy
- Maintain a regular schedule
- Use the bed only for sleep and sex
- Leave the bed if unable to fall asleep within 20 minutes
- Return to bed only when sleepy again 1
Relaxation training (Standard): Reduces somatic and cognitive arousal that interferes with sleep 1
- Progressive muscle relaxation involves methodically tensing and relaxing different muscle groups 1
Sleep restriction (Guideline): Limits time in bed to match actual sleep time 1
- Maintain sleep logs to determine mean total sleep time
- Set bedtime and wake time to achieve >85% sleep efficiency
- Make weekly adjustments based on sleep efficiency 1
Cognitive therapy: Addresses dysfunctional beliefs and attitudes about sleep 1
Second-Line Treatment: Pharmacotherapy
- If CBT-I alone is unsuccessful, clinicians should use a shared decision-making approach to discuss adding pharmacological therapy 1, 6
- Short to intermediate-acting benzodiazepine receptor agonists (BzRAs) or ramelteon are recommended as first pharmacological options 1, 7
Medication Selection Considerations
- For sleep onset difficulties: Consider zaleplon or ramelteon due to their short half-lives 1
- For sleep maintenance problems: Consider eszopiclone or temazepam with relatively longer half-lives 1
- For patients with substance use history: Ramelteon may be appropriate as it is not a DEA-scheduled drug 1
Important Medication Considerations
- Start at the lowest available dose, especially in older adults 6
- Zolpidem 10mg has shown efficacy for chronic insomnia in controlled studies, improving sleep latency and efficiency 7
- Be aware of potential adverse effects including residual sedation, memory impairment, falls (especially in older adults), and anterograde amnesia 6, 7
Special Considerations for Older Adults
- CBT-I remains highly effective in older adults and should still be first-line treatment 2, 6
- Pharmacological treatments carry increased risks in older adults due to pharmacokinetic changes 6
- Medication-related risks include falls, fractures, cognitive impairment, and potential for dependence 6
Implementation and Monitoring
- Collect sleep diary data before and during treatment 2, 6
- Follow up regularly until insomnia stabilizes, then every 6 months 2, 6
- Evaluate for improvement in sleep parameters (sleep onset latency <30 minutes, wake after sleep onset <30 minutes, sleep efficiency >80-85%) 1
Common Pitfalls to Avoid
- Relying solely on sleep hygiene without other behavioral interventions 6
- Using over-the-counter antihistamines or herbal supplements without sufficient evidence 6
- Prescribing benzodiazepines as first-line agents, especially in older adults 6
- Continuing ineffective treatments without reassessment 6
- Failing to address underlying medical or psychiatric conditions contributing to insomnia 6
