Melatonin tablets product information

Melatonin hormone tablets (known as Circadin) contains melatonin which is originally produced in our body to regulate sleep and wakefulness. It is originally used for insomnia (difficulty sleeping) but has been widely used for relieving symptoms of jet lag.

How to take

You should take melatonin hormone tablets as prescribed by your doctor.

You should take it after food, 1-2 hours before bedtime.

Avoid alcohol before, during or after taking the tablets as alcohol can reduce the effectiveness of melatonin.

Side effects of Melatonin tablets

Like all medicines, Melatonin tablets can cause some side effects, although not everyone gets them.

Side effects are generally uncommon but can include feeling tired or sleeping, headache and indigestion. Side effects are mild  but if you are concerned about any of these, you should speak to a doctor or pharmacist for advice. It is important that if you experience drowsiness that you avoid driving or operating machinery.

However, if you experience some serious side effects such as chest pain (uncommon), visual impairment (rare) or depression (rare), you should stop taking Melatonin tablets and seek urgent medical advice.

The full list of side effects can be found on the patient information leaflet attached below.


When ordering from Medicinesbymailbox, you may be required to fill in a series of Yes/No questionnaires to determine your suitability to the medicines. You should NOT take melatonin tablets without consulting a doctor if you:
  • are allergic to melatonin
  • have liver or kidney problems
  • have auto-immune diseases (if you are unsure about this, speak to a doctor)

Some medications can interact with melatonin tablets, such as some sleeping tablets (benzodiazepines, zopiclone, zaleplone), some blood pressure medications (adrenergic agonists), and fluvoxamine used for the treatment of depression. If you are unsure about your current medications, you should speak to a doctor or pharmacist.
