Can You Become Dependent on Melatonin?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Melatonin does not cause physical dependence or withdrawal symptoms like prescription sleep medications. Unlike benzodiazepines or Z-drugs, melatonin is a naturally occurring hormone that supplements your body's own production. However, psychological dependence can develop where you feel unable to sleep without it. Studies show that 3-5 mg doses taken 1-2 hours before bedtime are most effective for sleep regulation. Long-term use may slightly suppress natural melatonin production, but this typically reverses within days of stopping. Most sleep specialists recommend using melatonin intermittently rather than nightly to maintain your body's natural sleep-wake cycle and avoid psychological reliance.
