Best Sleep Aid for an 85-Year-Old Female

Cognitive Behavioral Therapy for Insomnia (CBT-I) is the recommended first-line treatment for sleep disturbances in elderly patients, with low-dose trazodone (25-50mg) as the preferred pharmacological option when non-pharmacological approaches are insufficient. 1

Non-Pharmacological Approaches (First-Line)

1. Cognitive Behavioral Therapy for Insomnia (CBT-I)

• Most effective non-pharmacological intervention with strong evidence for improving sleep quality, duration, and efficiency 1
• Should be attempted for 4-6 weeks before considering medication 1
• Components include:
  • Sleep restriction therapy
  • Stimulus control
  • Cognitive restructuring of sleep-related thoughts
  • Relaxation techniques

2. Sleep Hygiene Practices

• Maintain regular sleep-wake schedule (same bedtime and wake time)
• Ensure exposure to bright light during the day
• Keep bedroom dark, quiet, and comfortable
• Avoid heavy meals, alcohol, and nicotine before bedtime
• Avoid caffeine and daytime naps 1

3. Additional Non-Pharmacological Options

• Regular morning or afternoon exercise (improves sleep quality) 1
• Progressive muscle relaxation (reduces somatic arousal) 1
• Mindfulness meditation (significantly decreases sleep disturbance) 1, 2
• Light therapy (helps establish normal sleep patterns) 1

Pharmacological Approaches (Second-Line)

If non-pharmacological approaches fail after 4-6 weeks, consider medication:

1. Preferred Option: Trazodone

• Recommended dose: 25-50mg at bedtime 1, 3
• Preferred over benzodiazepines in elderly patients 1
• Better safety profile than benzodiazepines in older adults 1
• Start at lowest dose (25mg) and titrate as needed 3

2. Alternative Options:

• Mirtazapine (7.5-15mg): Useful when depression and insomnia coexist 1
• Melatonin: May help establish normal sleep patterns in older adults 4, 5
  • British Association for Psychopharmacology recommends prolonged-release melatonin as first-line for insomnia in persons over 55 years 4

Medications to Avoid

• Benzodiazepines (e.g., lorazepam): High risk in elderly due to:

  • Prolonged sedation
  • Increased fall risk
  • Cognitive impairment
  • Respiratory depression 4, 1, 6

• Long-acting benzodiazepines: Particularly problematic due to:

  • Half-lives longer than 24 hours
  • Accumulation with multiple doses
  • Impaired clearance in older patients 4

• Antihistamines (e.g., diphenhydramine/Benadryl):

  • Risk of daytime sedation and delirium in older patients 4
  • Not recommended due to anticholinergic effects 4, 1

• Over-the-counter sleep aids:

  • Lack of demonstrated efficacy
  • Safety concerns 4

Treatment Algorithm

1. Start with CBT-I and sleep hygiene for 4-6 weeks
2. If insufficient response: Add trazodone 25mg at bedtime
3. Reassess in 2-4 weeks:
   • If improved but suboptimal: May increase to 50mg
   • If no improvement: Consider switching to mirtazapine 7.5mg or melatonin
4. Reevaluate regularly: Attempt gradual withdrawal when stability is achieved 1

Important Considerations for Elderly Patients

• Start with lower doses than would be used in younger adults
• Monitor for daytime sedation, cognitive effects, and fall risk
• Check for medication interactions (common in elderly patients)
• Evaluate for underlying conditions that may affect sleep (pain, depression, restless leg syndrome)
• Consider checking ferritin levels (treat if below 45-50 ng/mL) 1

Common Pitfalls to Avoid

• Relying solely on sleep hygiene without additional interventions
• Using sedating medications long-term without addressing underlying causes
• Ignoring comorbid conditions that may affect sleep 1
• Prescribing benzodiazepines or anticholinergic medications due to their high risk in elderly patients 4, 1
