Why

Worth using for flights crossing five or more time zones, and the benefit is larger going east than west - eastward travel asks the body clock to advance, which it does badly on its own. The dose is wide because the trials found little difference across it; 5 mg got people to sleep faster than the lower doses. What matters more than the number is the clock.

Cautions
  • Timing is the whole treatment. Taken early in the day it makes jet lag worse - it causes daytime sleepiness and delays the body clock adapting.
  • Case reports of harm in epilepsy and in patients taking warfarin. Avoid in both unless a specialist has agreed it.
  • Do not drive or operate machinery for several hours after a dose.
  • Melatonin is sold in Egypt as a supplement as well as a medicine, and content has been found not to match the label in some commercial products. Prefer a registered pharmaceutical pack.
