Prescribing melatonin

Prescribing melatonin

If a prescriber decides to prescribe an unlicensed or off-label medicine, they must follow their professional guidance. For doctors this is the General Medical Council's good practice guidelines. This guidance includes giving information about the treatment and discussing the possible benefits and harms so that the patient, and their parent or carer if appropriate, has enough information to decide whether or not to have the treatment. This is called giving informed consent.

The full version of the summary aimed at healthcare professionals is available at The summary for healthcare professionals does not contain recommendations from NICE on whether the medicine should be used.
