Dosing Schedule for Insomnia Medications

For insomnia treatment, recommended dosages include zolpidem 10mg (adults) or 5mg (elderly), zaleplon 10mg, ramelteon 8mg for sleep onset issues; and doxepin 3-6mg, eszopiclone 2-3mg, temazepam 15mg, or suvorexant 10-20mg for sleep maintenance issues. 1

First-Line Medication Options

Sleep Onset Insomnia

  • Zolpidem: 10mg for adults, 5mg for elderly patients
  • Zaleplon: 10mg at bedtime
  • Ramelteon: 8mg at bedtime (particularly beneficial for patients with substance abuse history due to lack of abuse potential)

Sleep Maintenance Insomnia

  • Doxepin: 3-6mg at bedtime (particularly suitable for elderly patients)
  • Eszopiclone: 2-3mg at bedtime
  • Temazepam: 15mg at bedtime
  • Suvorexant: 10-20mg at bedtime

Additional Medication Options

  • Trazodone: 25-100mg at bedtime - effective for decreasing nighttime awakening frequency 1
  • Mirtazapine: 7.5-30mg at bedtime - effective for both sleep onset and maintenance issues (note: may stimulate appetite) 1

Special Population Considerations

Elderly Patients

  • Lower doses are recommended:
    • Zolpidem: 5mg
    • Eszopiclone: 1-2mg
    • Doxepin: 3-6mg (preferred due to fewer anticholinergic effects and minimal next-day impairment) 1

PTSD-Related Insomnia

  • Prazosin: First-line medication for PTSD-related insomnia and nightmares 1
  • Clonidine: Starting at 0.1mg twice daily, titrate as needed 1
  • Gabapentin: Starting at 300mg at bedtime, titrate to effective dose (typically 900-1800mg daily) 1

Efficacy and Safety Considerations

Eszopiclone has demonstrated efficacy in reducing sleep latency and improving sleep maintenance in clinical studies lasting up to 6 months 2. The 3mg dose was superior to placebo on wake time after sleep onset (WASO) measures 2.

Important Cautions

  • Next-day impairment: Eszopiclone 3mg has been associated with next-morning psychomotor and memory impairment that can persist for up to 11.5 hours after dosing 2
  • Withdrawal concerns: Abrupt discontinuation may lead to rebound insomnia. Gradual tapering is recommended when discontinuing after more than a few days of use 3
  • Memory impairment: Reported in 1-1.5% of patients taking eszopiclone 2

Medications to Avoid

  • Benzodiazepines: Should be avoided for long-term management due to risks of dependency, cognitive impairment, falls, and respiratory depression 1
  • Antihistamines: Should be avoided due to antimuscarinic effects and rapid development of tolerance 3, 1
  • Antipsychotics (including quetiapine): Have sparse evidence with significant harms, including increased mortality risk in elderly patients with dementia 1
  • Alcohol: Not recommended due to short duration of action, adverse effects on sleep, exacerbation of obstructive sleep apnea, and potential for abuse 3

Treatment Duration and Monitoring

  • Assess response to treatment within 2-4 weeks of initiation 1
  • Monitor for side effects such as daytime sedation, cognitive changes, and falls 1
  • For long-term use, consider periodic attempts to reduce the frequency and dose to determine the lowest effective dose 3
  • When discontinuing medication after more than a few days of use, taper both the dose and frequency of administration gradually to minimize rebound insomnia and withdrawal effects 3

Common Pitfalls to Avoid

  1. Failing to adjust dosage for elderly patients, who require lower doses due to altered pharmacokinetics
  2. Continuing medications long-term without attempting dose reduction or medication-free periods
  3. Abrupt discontinuation of hypnotic medication, which can lead to rebound insomnia and withdrawal symptoms
  4. Not addressing underlying causes of insomnia before initiating pharmacotherapy
  5. Using over-the-counter sleep aids long-term, which is not recommended due to limited efficacy and safety data 3
