Approach to Primary Insomnia in Young Adults

First-Line Treatment: CBT-I

The American College of Physicians recommends Cognitive Behavioral Therapy for Insomnia (CBT-I) as first-line therapy for all adults with chronic insomnia disorder due to superior long-term efficacy and minimal adverse effects compared to medications 1, 2
CBT-I is the gold standard initial treatment with moderate-strength evidence demonstrating improvements in sleep onset latency, wake after sleep onset, sleep efficiency, and total sleep time compared to waitlist or information controls 1
CBT-I consists of multiple evidence-based components, including cognitive restructuring, which addresses dysfunctional beliefs about sleep and catastrophic thinking about insomnia consequences 1

Stimulus control therapy is a standard recommendation, where the patient should use the bed only for sleep, leave the bed if unable to sleep within approximately 20 minutes, and return only when drowsy 3

CBT-I can be effectively delivered through multiple formats, including individual therapy sessions, group therapy, telephone-based programs, web-based modules, and self-help books, all showing comparable efficacy 2, 4

Pharmacological treatment should only supplement—never replace—CBT-I, and is reserved for situations where behavioral interventions alone are insufficient or while CBT-I is being implemented 3, 4

For sleep onset insomnia, zolpidem 10 mg has proven efficacy for reducing sleep latency 3, 4
For combined sleep onset and maintenance insomnia, eszopiclone 2-3 mg addresses both initiation and maintenance 4

Use the lowest effective dose for the shortest duration possible, typically less than 4 weeks for acute exacerbations 3, 4
Always combine pharmacotherapy with CBT-I implementation, as short-term hypnotic treatment should be supplemented with behavioral interventions 4

Over-the-counter antihistamines (diphenhydramine) are not recommended due to lack of efficacy data, anticholinergic side effects, and daytime sedation 3, 4
Antipsychotics should not be used as first-line treatment due to problematic metabolic side effects and lack of evidence 3

Starting with medications before attempting CBT-I violates guideline recommendations and deprives patients of more effective, durable therapy with superior long-term outcomes 1, 2, 4
Relying on sleep hygiene education alone lacks efficacy as a single intervention and must be combined with other CBT-I components like stimulus control and sleep restriction 4

Improvements from CBT-I are gradual but durable beyond treatment end, with benefits sustained up to 2 years post-treatment 5
In contrast, medications provide rapid symptom relief but do not address underlying perpetuating mechanisms and lose efficacy after discontinuation 1
