Quick answer

Melatonin tablet: indications and effects

What it is:
Melatonin is a hormone normally released by the pineal gland at night. It helps regulate the body’s circadian rhythm, or sleep-wake clock. Tablets are mainly used to adjust sleep timing rather than as a strong sedative.

Common indications

Jet lag, especially after travel across several time zones.
Delayed sleep-wake phase disorder: sleeping very late and difficulty waking at the desired time.
Shift-work related sleep disturbance in selected people.
Short-term insomnia, particularly difficulty falling asleep, when a clinician considers it appropriate.
Circadian sleep disorders in blind people, including non-24-hour sleep-wake disorder.
Sometimes used for sleep difficulty in certain neurologic or developmental conditions, under medical guidance.

Effects

May reduce the time needed to fall asleep.
Can help shift the body clock earlier or later depending on when it is taken.
May improve sleep timing and quality in jet lag or circadian-rhythm problems.
It does not always work well for chronic insomnia, especially if sleep problems are driven by anxiety, pain, depression, caffeine, sleep apnea, or poor sleep habits.

Common side effects

Next-day drowsiness or tiredness
Headache
Dizziness
Nausea or stomach upset
Vivid dreams or nightmares
Irritability or mood changes in some people

Important precautions

Do not drive, drink alcohol, or operate machinery if sleepy after taking it.
Check with a clinician or pharmacist before use if you are pregnant or breastfeeding, have liver/kidney disease, epilepsy, autoimmune disease, or take regular medicines.
Drug interactions can occur, including with sedatives, alcohol, anticoagulants such as warfarin, some antidepressants, blood-pressure medicines, and diabetes medicines.
For children, use only on a pediatric clinician’s advice.
Product quality and dose can vary where melatonin is sold as a supplement.

Melatonin usually works best when taken at the correct time for the sleep problem, not simply at bedtime.

What is the correct melatonin dose and timing for my sleep problem?

Reading File

The correct timing depends on the pattern: trouble falling asleep, waking during the night, an advanced/delayed body clock, shift work, or jet lag.

melatonin dosage timing jet lag delayed sleep wake phase insomnia NHS

The correct dose and timing depend on the type of sleep problem, your age, other medicines, and the product type. I cannot safely give a personal regimen without those details, but these are typical adult approaches:

Sleep pattern	Typical starting approach
Difficulty falling asleep at a normal bedtime	Low-dose immediate-release melatonin, often 0.5 to 1 mg, 1 to 2 hours before the intended bedtime. Avoid taking it in the middle of the night.
You naturally fall asleep very late and cannot wake early (delayed sleep phase)	Usually 0.5 mg about 4 to 5 hours before your current natural sleep-onset time, combined with a fixed wake-up time and bright morning light. Timing matters more than increasing the dose.
Jet lag	A common short course is 3 mg at local bedtime after arrival, for up to 5 nights. Do not take it earlier than 8 pm or later than 4 am local time, per NHS dosing advice.
Waking frequently during the night / early-morning waking	Do not self-dose in the night. A clinician may consider a prolonged-release product, but this pattern can also reflect sleep apnea, depression, pain, alcohol, or medication effects.
Shift work	Individualize with a sleep clinician or pharmacist. Wrong timing can further shift the body clock and worsen alertness at work.

General use

Start with the lowest effective dose, rather than high doses such as 5 to 10 mg.
Take it only when you can allow 7 to 8 hours for sleep.
Avoid alcohol and driving after taking it.
If it causes morning grogginess, vivid dreams, dizziness, or headache, reduce the dose or stop and seek advice.
For persistent insomnia, sleep habits and CBT-I are generally more useful than indefinite melatonin use.

Do not start or adjust it without clinician/pharmacist advice if you are under 18, pregnant or breastfeeding, age 65+, have epilepsy, autoimmune or liver disease, or take medicines such as warfarin/blood thinners, sedatives, antidepressants, diabetes medicines, or blood-pressure medicines.

Reply with: your age, sleep schedule, whether you cannot fall asleep or wake too early/often, shift work or jet lag, and medicines/conditions. Then I can help identify the safest timing range to discuss with your clinician or pharmacist.

Every prescription medicine and supplement, with dose and time taken

Do not take melatonin without pharmacist or prescriber advice if you take a blood thinner such as warfarin, sedatives/sleeping medicines, opioids, or certain antidepressants, because interactions can increase bleeding risk or excessive drowsiness.
