Insomnia Management with Trazodone

Introduction to Trazodone for Insomnia

• The American Academy of Sleep Medicine provides a weak recommendation against using trazodone for sleep onset or maintenance insomnia, based on clinical trial evidence showing limited efficacy, with sleep latency reduction of only 10.2 minutes, total sleep time increase of only 21.8 minutes, wake after sleep onset reduction of only 7.7 minutes, and insignificant sleep quality improvement of -0.13 points on a 4-point scale 1

Efficacy and Side Effects

• Trazodone at a dose of 50 mg at bedtime is recommended for sleep in patients taking sertraline 50 mg, though evidence suggests limited efficacy for insomnia compared to other options 1
• Common side effects of trazodone when used for sleep include headache (30% vs 19% with placebo) and somnolence/daytime drowsiness (23% vs 8% with placebo) 1

Alternative Therapies

• The American Academy of Sleep Medicine recommends Cognitive Behavioral Therapy for Insomnia (CBT-I) as a first-line non-pharmacological alternative 2
• Pharmacological alternatives include Zolpidem 10 mg (5 mg in elderly) with the strongest evidence for sleep onset, Eszopiclone 2-3 mg effective for both onset and maintenance, and Doxepin 3-6 mg effective for sleep maintenance with minimal side effects 2

Special Considerations

• Elderly patients should start with 25 mg and titrate cautiously due to increased risk of falls and orthostatic hypotension 1
• Patients with cardiac conditions should use trazodone with caution due to potential for QT prolongation 1
• Patients with liver impairment may require lower doses 1
