Treatment of Sleep-Onset Insomnia

Initial Non-Pharmacological Approach

The American College of Physicians provides a strong recommendation (Grade: strong recommendation, moderate-quality evidence) that all adult patients receive cognitive behavioral therapy for insomnia (CBT-I) as initial treatment for chronic insomnia 1
CBT-I combines cognitive therapy, behavioral interventions (sleep restriction and stimulus control), and sleep hygiene education, and can be delivered through in-person sessions, telephone/web-based modules, or self-help books 1
This approach is particularly appropriate since the patient is already responding to escitalopram for depression and anxiety, meaning the insomnia may be a residual symptom or medication side effect rather than a primary manifestation of untreated mood disorder 1

Short-acting benzodiazepine receptor agonists are the preferred first-line pharmacological option 2, 3
Zolpidem 10 mg at bedtime is primarily used for sleep-onset insomnia, short-to-intermediate acting 3
Eszopiclone 2-3 mg at bedtime is used for sleep-onset and maintenance, with no short-term usage restriction 3
Low-dose trazodone (50-100 mg at bedtime) can be added to escitalopram if maintaining the current antidepressant is preferred 2, 3, 4
Low-dose doxepin (3-6 mg) is FDA-approved specifically for insomnia characterized by sleep maintenance difficulties, though it can help with sleep onset as well 5, 6

SSRIs including escitalopram can cause or exacerbate insomnia through serotonin-2 (5-HT2) receptor stimulation 7

Over-the-counter antihistamines and herbal supplements (valerian, melatonin) are NOT recommended for chronic insomnia due to lack of efficacy and safety data 2
Older sedatives including barbiturates and chloral hydrate should not be used 2

The American College of Physicians recommends using shared decision-making when adding pharmacotherapy, discussing benefits, harms, and costs of short-term medication use 5, 8
Patients should be followed every few weeks initially to assess effectiveness, side effects, and need for ongoing medication 2
Employ the lowest effective maintenance dose and attempt to taper medication when conditions allow 2
Medication tapering is facilitated by concurrent CBT-I 2
