- Starting Point: Generally, beginning with a lower amount is considered a reasonable starting point for addressing minor adjustments and jet lag, potentially with fewer side effects. [1, 2]
- Adjusting Intake: If lower amounts do not sufficiently shift the sleep cycle, some adults may work with a healthcare provider to adjust their intake, though higher amounts might increase the likelihood of side effects without offering additional benefits. [1, 2, 3]
- Timing: For effectiveness, melatonin is generally taken in the evening, roughly 30 to 60 minutes before the target bedtime. [1, 2]
- Eastward Travel: Taking melatonin in the early evening (around local bedtime) for a few days before and after arrival can help advance the body clock. [1, 2]
- Westward Travel: While this often involves delaying the body clock, where light exposure management is crucial, a small evening amount can sometimes assist if there is trouble staying asleep. [1, 2, 3, 4]
- Duration: Melatonin is typically used short-term, generally for up to 5 days, until the body adjusts to the new local time zone. [1, 2, 3, 4]
- Potential Side Effects: Higher amounts may lead to side effects like daytime sleepiness, vivid dreams, or headaches.
- Interactions: It is advisable to avoid combining melatonin with alcohol or sedatives. [1, 2, 3]
