    Is trazodone or melatonin better for sleep?

    Neither is a universal first choice for chronic insomnia. Trazodone is an antidepressant that can be sedating; melatonin acts on sleep timing. The cause of insomnia, other conditions and the treatment goal determine the comparison. Cognitive behavioral therapy for insomnia is central to guideline-based chronic-insomnia care.

    They act in different treatment contexts

    NHS describes trazodone as a treatment for depression and anxiety with possible sleepiness. Melatonin is a hormone involved in circadian timing and has selected sleep-related uses. Sedation is not the same as correcting a circadian problem or providing effective long-term insomnia treatment. [1][2]

    Guidelines do not identify either as the default winner

    The 2026 AASM combination guideline reviews the earlier conditional recommendations against trazodone and melatonin for routine chronic-insomnia pharmacotherapy because of limited evidence and other considerations. It emphasizes CBT-I and individualized decisions about adding medication. These recommendations do not mean either medicine has no role in any patient or diagnosis. [3]

    Compare harms and the reason for prescribing

    Trazodone can cause dizziness and daytime sleepiness and should not be stopped abruptly without a prescriber’s plan. Melatonin can also impair alertness, interact with medicines and has limited long-term safety evidence. There is no valid milligram-for-milligram conversion between them. [1][2]

    Make a goal-based choice

    Imagine trazodone is treating depression as well as sleep symptoms. Replacing it with melatonin could leave the underlying treatment need unmet. Discuss whether the problem is chronic insomnia, a timing disorder or another condition, and use that assessment to select care. [1][3]
