Trazodone vs. Halcion
See how Trazodone and Halcion compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Trazodone is FDA-approved for depression but most often prescribed off-label at low doses for insomnia, while Halcion is FDA-approved specifically for short-term insomnia treatment.
Halcion is a Schedule IV controlled substance with a boxed warning for abuse, misuse, and dangerous interactions with opioids, while trazodone carries no such controlled-substance risk.
Halcion is meant for short courses of about 7 to 10 days, while trazodone is sometimes continued nightly for longer stretches under a doctor's supervision.
Trazodone vs. Halcion Drug Summary
Trazodone
Trazodone is an atypical antidepressant, a serotonin antagonist and reuptake inhibitor, that the FDA has approved to treat major depressive disorder. At low doses, it is commonly prescribed off-label as a sleep aid, taken as a tablet about 30 to 60 minutes before bedtime. It is not a controlled substance and does not carry the dependency risks associated with benzodiazepine sleep aids.
Halcion
Halcion (triazolam) is a benzodiazepine sedative-hypnotic that the FDA has approved specifically for short-term treatment of insomnia, generally lasting 7 to 10 days. It is taken as a tablet once daily at bedtime and is a Schedule IV controlled substance because of its potential for misuse and dependence. It is not intended for long-term nightly use without medical re-evaluation.

Trazodone vs. Halcion Indications
Trazodone
Trazodone's only FDA-approved use is major depressive disorder, not insomnia. Despite this, it is one of the most frequently prescribed off-label sleep aids in the United States, typically used at doses far lower than those needed for depression.
FDA-approved for major depressive disorder
Off-label use for insomnia at low doses (25-100 mg)
Sometimes used off-label for anxiety or PTSD-related sleep issues
Not approved for use in children or adolescents
Halcion
Halcion's only FDA-approved use is short-term treatment of insomnia, generally limited to 7 to 10 days of nightly use. It is not approved for long-term nightly use, for daytime anxiety, or for any other condition, and requires re-evaluation if insomnia persists.
FDA-approved for short-term insomnia treatment
Limited to about 7 to 10 days of use per FDA labeling
Not approved for long-term or chronic insomnia
Approved for adults only
Trazodone vs. Halcion Pros and Cons
Trazodone
Trazodone is not a controlled substance, so it carries none of the abuse, misuse, or opioid-interaction warnings that come with benzodiazepine hypnotics. Because it is FDA-approved for depression rather than sleep, dosing for insomnia is based on clinical experience rather than dedicated FDA-reviewed sleep trials.
Pros
No controlled-substance status or abuse-related boxed warnings
Can be continued nightly for months under medical supervision
Also treats coexisting depression or anxiety symptoms
Lower risk of next-day memory impairment than benzodiazepines
Cons
Insomnia dosing is off-label, without FDA-reviewed sleep trials
Can cause priapism, a rare but serious condition in men
Can prolong the QT interval and affect heart rhythm
Sedation can take longer to kick in than fast-acting benzodiazepines
Halcion
Halcion is FDA-approved specifically for insomnia, so its dosing and short-term efficacy are backed by dedicated sleep trials. Its Schedule IV status means it carries boxed warnings for abuse, dependence, and dangerous interactions with opioids that trazodone does not share.
Pros
FDA-approved dosing and trials specific to insomnia
Fast onset, well suited for trouble falling asleep
Effective at very low milligram doses
Short half-life limits next-day carryover sedation
Cons
Schedule IV controlled substance with abuse and dependence risk
Boxed warning for dangerous interactions with opioids
Not intended for use beyond about 7 to 10 days
Higher rate of anterograde amnesia than some other benzodiazepine hypnotics
