Jet Lag Assessment

Do not order medication for another patient or order multiple medications for different patients on a SINGLE order. Please register separate accounts for each patient as each account is treated as a medical record.

Melatonin is not advised during pregnancy. Appropriate contraception (including a barrier method for male patients) is recommended during treatment.

Jet lag treatment is usually only advised if there is a time difference of 3 or more hours from your starting country to your destination.

Smoking may reduce the effectiveness of the treatment.

I understand that:

• Melatonin can cause drowsiness and I should not drive or operate heavy machinery for at least 8 hours after taking it.
• Melatonin should be taken daily, at my intended bedtime in the new time zone. It should only be taken between the hours of 8pm and 4am and should not be taken for more than 5 days.
• Recent studies have suggested melatonin may increase the risk of falls and accidents.
• I should not take melatonin with alcohol.
• Melatonin is a medication that helps sleep, it can therefore increase the sleepiness or lower blood pressure when taken with other medications that cause these. If I experience light-headedness, fuzziness, or excessive sleepiness I will immediately stop melatonin and seek advice.
