Melatonin is the body's own darkness signal, taken as a short course at destination bedtime to pull the body clock toward local time after eastward flights across multiple zones.

The condition it treats

Jet lag is the misalignment between the internal clock and destination time: broken nights, daytime fog and gut upset that can consume half of a short trip. Timed melatonin plus light-exposure strategy compresses the adjustment.

How the service runs on Scripter

Patients book online, complete the pre-consultation questionnaire, and the guided pathway walks the practitioner through the jet lag consultation with the screening and counselling steps built in. The supply decision, the record and any GP notification are produced in the same flow, documented against the exact protocol version in force.

Training and eligibility requirements.

Who can deliver this service, and who it can be delivered to. The governing PGD document defines the definitive inclusion, exclusion and supply criteria; the Scripter consultation pathway enforces them, and every consultation is documented against the protocol version it ran under.

Melatonin PGD questions

When exactly is melatonin taken?+

At destination bedtime for a few nights after arrival, especially eastward; the consultation writes the actual clock times for the itinerary so nothing is left to jet-lagged arithmetic.

Is it a sleeping tablet?+

Not really; it is a clock signal more than a sedative. It tells the brain when night is, which is why timing matters more than dose.

Does it work for westward flights?+

Benefit is clearest flying east; westward adaptation is easier and light management alone often suffices, which the counselling covers honestly.
