Sleep Aids for a 71-Year-Old with Insomnia

Cognitive Behavioral Therapy for Insomnia (CBT-I) is strongly recommended as the first-line treatment for insomnia in older adults due to its proven efficacy, long-term benefits, and minimal side effects compared to pharmacological options. 1

Non-Pharmacological Approaches (First-Line)

Cognitive Behavioral Therapy for Insomnia (CBT-I)

• Multiple guidelines strongly support CBT-I as the most effective first-line treatment for chronic insomnia in older adults 2, 1
• Components include:
  • Sleep restriction therapy (limiting time in bed to match actual sleep time)
  • Stimulus control (using bed only for sleep and sex, leaving bed if unable to sleep)
  • Relaxation techniques (deep breathing, progressive muscle relaxation)
  • Sleep hygiene education

Implementation Options

• Face-to-face CBT-I with a trained provider is the gold standard
• Alternative delivery methods when access is limited:
  • Telehealth/telemedicine sessions
  • Self-directed internet-based programs
  • Group therapy sessions 2

Pharmacological Options (Second-Line)

If CBT-I is unsuccessful or while waiting for CBT-I to take effect, consider these medication options with caution:

Safer Options for Older Adults

1. Low-dose doxepin (3-6mg)

   • Effective for sleep maintenance issues
   • Minimal anticholinergic effects at low doses 1
   • Lower risk of side effects compared to other sleep medications in elderly

2. Melatonin (1-3mg)

   • Drug-free and non-habit forming 3
   • Helps establish normal sleep patterns
   • Start with 1mg and increase if needed
   • Take 1-2 hours before bedtime

3. Ramelteon (8mg)

   • Targets melatonin receptors
   • Specifically helps with sleep onset difficulties
   • Lower risk of falls and cognitive impairment than benzodiazepines 1

Medications to Use with Extreme Caution

1. Trazodone
   • Can be used at lower doses (25-50mg) in elderly 1, 4
   • Should be taken shortly after a meal or light snack 4
   • Monitor for orthostatic hypotension and cardiac effects

Important Precautions for Older Adults

Medications to Avoid

• Benzodiazepines (temazepam, diazepam): High risk of falls, cognitive impairment, and dependency 1
• Z-drugs (zolpidem, zopiclone): Associated with cognitive and behavioral changes, impaired driving, and memory loss 5
• Quetiapine and other antipsychotics: Significant safety concerns when used for insomnia 1
• Antihistamines: Limited evidence for effectiveness and high anticholinergic burden

Special Considerations for the Elderly

• Start with lower medication doses (typically half the adult dose) 1
• Monitor for adverse effects, particularly daytime sedation and falls
• Use medications for the shortest duration possible
• Regularly reassess the need for continued medication

Monitoring and Follow-up

• Schedule follow-up within 2-4 weeks to assess effectiveness and side effects 1
• Gradually taper medications when discontinuing to avoid rebound insomnia
• Consider "refresher" sessions of CBT-I to maintain long-term benefits 6

Treatment Algorithm

1. Start with CBT-I as first-line treatment
2. If immediate relief is needed while waiting for CBT-I effects:
   • Try melatonin 1-3mg first for minimal side effects
   • If ineffective, consider low-dose doxepin (3-6mg) for sleep maintenance or ramelteon (8mg) for sleep onset issues
3. Avoid benzodiazepines, Z-drugs, and antihistamines due to high risk of adverse effects in elderly
4. Reassess regularly and discontinue medications as soon as possible

Remember that sleep problems in older adults are often multifactorial and may be related to underlying medical conditions, medications, or normal age-related changes in sleep architecture 7. Addressing these underlying factors is crucial for long-term management.
