Initial Approach to Managing Insomnia
Cognitive Behavioral Therapy for Insomnia (CBT-I) should be the first-line treatment for patients with insomnia due to its proven efficacy and long-term benefits with minimal side effects. 1
Initial Assessment and Diagnosis
- Evaluate for co-morbid conditions as sleep disturbances may be a manifestation of underlying physical or psychiatric disorders 1, 2, 3, 4
- If insomnia doesn't improve after 7-10 days of treatment, consider unrecognized primary medical or psychiatric illness 2, 3, 4
- Assess for:
- Sleep patterns (onset, maintenance, early morning awakening)
- Duration of symptoms
- Daytime functioning impairment
- Current sleep habits and environment
- Medication use (including OTC and supplements)
- Substance use (caffeine, alcohol, tobacco)
First-Line Treatment: CBT-I
CBT-I includes several evidence-based components:
Stimulus Control Therapy 1
- Go to bed only when sleepy
- Use bed only for sleep and sex
- Leave bed if unable to sleep within 15-20 minutes
- Maintain regular wake-up time regardless of sleep duration
Sleep Restriction Therapy 1
- Limit time in bed to match actual sleep time
- Gradually increase time in bed as sleep efficiency improves
- Target sleep efficiency >85%
Relaxation Training 1
- Progressive muscle relaxation
- Deep breathing exercises
- Meditation techniques
- Identify and challenge unhelpful beliefs about sleep
- Address excessive worry about consequences of poor sleep
Sleep Hygiene Education 1
- Regular sleep schedule
- Limit caffeine and alcohol
- Create comfortable sleep environment
- Note: Sleep hygiene alone is insufficient and should be used as an adjunct to other CBT-I components 5
Pharmacological Interventions (Second-Line)
If CBT-I is not immediately available or for short-term use while initiating CBT-I:
For Sleep Onset Insomnia:
- Targets melatonin receptors
- Lower risk of next-day impairment
- Caution: May affect reproductive hormones 4
Zolpidem 10mg (5mg in elderly) 1, 3
- Caution: Risk of complex sleep behaviors, next-day impairment 3
Zaleplon 10mg 1
For Sleep Maintenance Insomnia:
- Low-dose doxepin 3-6mg 1
- Eszopiclone 2-3mg 1, 2
- Caution: CNS depressant effects, next-day impairment 2
- Suvorexant 10-20mg 1
Important Precautions with Medications
- Avoid benzodiazepines due to high risk of falls, cognitive impairment, and dependency 1
- Start with lower doses in elderly patients or those with liver impairment 1
- Monitor for complex sleep behaviors (sleep-walking, sleep-driving) with sedative-hypnotics 2, 3
- Avoid concomitant use of multiple CNS depressants 2, 3, 4
- Discontinue medication if angioedema or abnormal thinking/behavioral changes occur 2, 3, 4
Follow-up and Monitoring
- Schedule follow-up within 2-4 weeks to assess effectiveness and side effects 1
- For CBT-I, typical treatment duration is 6-8 sessions 6
- Treatment goals include: 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
Special Considerations
- CBT-I is effective for insomnia comorbid with psychiatric and medical conditions 1, 7
- For elderly patients, use lower medication doses and prioritize non-pharmacological approaches 1
- CBT-I has been shown effective for 70-80% of patients with sustained benefits 8
- When using medications, administer 30-60 minutes before desired sleep time 1
