Trazodone vs. Dayvigo
See how Trazodone and Dayvigo compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Trazodone is FDA-approved only for major depressive disorder, so using it for sleep is an off-label practice guided by a doctor's judgment, not an FDA-approved use.
Dayvigo is FDA-approved specifically for insomnia and works by blocking wake-promoting orexin signals instead of boosting GABA activity like older sleep drugs.
Trazodone is a low-cost generic with decades of use, while Dayvigo is newer, brand-only, and a Schedule IV controlled substance.
Trazodone vs. Dayvigo Drug Summary
Trazodone
Trazodone is a serotonin antagonist and reuptake inhibitor (SARI) that is FDA-approved to treat major depressive disorder in adults. It is not FDA-approved for insomnia, but it is widely prescribed off-label at lower doses to help people fall asleep. It comes as an oral tablet, usually taken once nightly for sleep or in divided doses for depression.
Dayvigo
Dayvigo (lemborexant) is a dual orexin receptor antagonist FDA-approved to treat insomnia in adults who have trouble falling asleep, staying asleep, or both. It is taken as a single 5 mg or 10 mg tablet each night, shortly before bed.

Trazodone vs. Dayvigo Indications
Trazodone
Trazodone's only FDA-approved use is major depressive disorder in adults, at doses much higher than those typically used for sleep. Using it for insomnia is off-label, meaning the FDA has not evaluated or approved it for that purpose, even though many doctors prescribe it this way at lower doses.
Major depressive disorder (FDA-approved)
Insomnia (off-label use only)
Often added to an SSRI for sleep (off-label)
Used off-label in patients with substance use risk
Dayvigo
Dayvigo is FDA-approved specifically for adults with insomnia, covering trouble falling asleep, staying asleep, or both. It is not approved for children or for narcolepsy, and its benefit has been studied with nightly use for up to 12 months.
Insomnia with difficulty falling asleep
Insomnia with difficulty staying asleep
Studied for nightly use up to 12 months
Not approved for narcolepsy or children
Trazodone vs. Dayvigo Pros and Cons
Trazodone
Trazodone's safety profile comes from depression trials at higher doses, not from studies designed around sleep, so its off-label use for insomnia relies on clinical experience rather than label guidance. Its low generic price and lack of controlled-substance status make it easy to access.
Pros
Roughly $5 to $25 a month as a generic, without insurance or savings programs
Not a controlled substance, so no special monitoring or refill limits
Decades of real-world use and safety data across many patient types
Cons
Not FDA-approved for insomnia, so sleep dosing relies on clinical experience rather than label guidance
Carries a boxed warning for increased suicidal thoughts in children and young adults
Can cause dry mouth, dizziness from low blood pressure, and next-day grogginess
Rare but serious risk of prolonged, painful erections (priapism) in men
Dayvigo
Dayvigo's safety and dosing data come from trials built specifically around insomnia, giving providers evidence matched to that exact use. That more targeted profile comes with a brand-only price and controlled-substance status.
Pros
Specifically FDA-approved for insomnia, with dosing built for sleep rather than adapted from another use
12-month trial data show sustained benefit without rebound insomnia after stopping
Works by blocking wake-promoting orexin receptors, a different mechanism than GABA-based sleep drugs
Cons
Roughly $135 to $400 a month, since no generic version exists yet
Schedule IV controlled substance with potential for misuse and dependence
Warning for complex sleep behaviors such as sleep-walking or sleep-driving
Not approved for use in children or for narcolepsy
