Melatonin is a signal for the body clock. Whether it suits a sleep problem therefore does not depend solely on how tired someone is. Sleep times, symptom duration, daytime sleepiness and possible causes should be assessed first.
Which question comes first?
| Situation | A useful next step |
|---|---|
| Shifted sleep-wake rhythm | Plan timing and daily rhythm together with a professional |
| Persistent difficulty falling or staying asleep | Assess causes and cognitive behavioural therapy for insomnia |
| Breathing pauses or marked daytime sleepiness | Obtain medical assessment independently of any melatonin product |
Timing and release pattern belong together
For jet lag or delayed sleep phase, a targeted time signal may have a role. This does not justify random dosing in the middle of the night. Immediate-release and prolonged-release products are also not interchangeable, even when the same milligram figure appears on the pack.
The 2023 European Insomnia Guideline recommends cognitive behavioural therapy as the first treatment for chronic insomnia. Limited use of prolonged-release melatonin in certain older patients is not a general recommendation for every freely sold spray or combination product.
Keep a sleep diary before the consultation
Record bedtime, waking time, nighttime wakefulness and how you feel the following day. Include caffeine, alcohol, medicines and the product used. Before starting a measure, agree what should improve and when benefits and unwanted effects will be reviewed.
Consider adverse effects and combinations
Headache, dizziness and next-day tiredness are possible. Do not drive or operate machinery when drowsy. Have combinations professionally reviewed with anticoagulants, epilepsy or other medicines. Children, pregnancy and breastfeeding are not appropriate settings for self-directed product trials.
Frequently asked questions
Is more melatonin automatically more effective?
No. A larger amount replaces neither the right diagnosis nor appropriate timing.
Can I replace necessary medicines with it?
No. Do not stop or change prescribed treatment yourself.
