About Melatonin tablets

Melatonin tablets contain the active medication melatonin. Melatonin 3mg tabs are used for the treatment of jet lag.

Jet lag, which often lasts a few days and can last up to a week or more, causes sleep disturbances, daytime tiredness, mild mental impairment, irritability, and reduced appetite. It is often unpleasant, and sometimes debilitating, affecting both business and holiday travel. Severity varies from person to person and on the number of time zones crossed, tending to be more severe in older people and with flights from east to west.

You should get medical advice if you do not feel better or if you feel worse after 5 days.

What is Melatonin medication?

Melatonin is a naturally occurring hormone which helps regulate the body's day-and-night clock. The biological clock can be disturbed by travelling across time zones leading to jet lag. The severity of symptoms varies between individuals, but are generally worse and last longer the more time zones that are crossed. Melatonin tablets can help restore the normal day-and-night rhythm and reduce jet lag symptoms.

Can I get Melatonin on the NHS?

Melatonin medication for the treatment of jet lag is considered to be a 'travel medication', and like other travel medicines, is not available through the NHS. It is a prescription medicine which Dr Fox supplies through a private online prescription, posted from our UK pharmacy.

How many tablets do I need?

Treatment is taken for up to 5 days after arriving when one or two tablets are taken each evening. One pack of 30 tablets is enough for up three or six treatments depending on the number of tablets taken each day. Frequent travellers can take up to 16 courses of treatment in a year.

Can anyone take Melatonin?

Most people can take Melatonin, although people with some pre-existing medical conditions or those taking certain medicines should not take it. Further information is listed in the patient information leaflet supplied with the tablets. Melatonin is not suitable for under 18s.

How to reduce jet lag without medication

  • Before you travel try going to bed at a time closer to the destination bedtime.
  • Try to make sure you have enough sleep in the days before you travel.
  • Keep as calm and relaxed as possible during travel.
  • Drink plenty to keep hydrated.
  • Avoid more than a little alcohol.
  • Move around during the flight when you can.
  • Adjust the time on your watch to the destination time at the start of the journey.
  • Sleep during the journey if travelling West.
  • On arrival try to sleep and eat at destination times.
  • Try to avoid naps in the day.
  • Spend time out of doors where natural light helps with adjustment.

Warnings/Cautions

Talk to your doctor before taking Melatonin medication, if the following apply:

  • Epilepsy - frequency of fits may increase.
  • Autoimmune disease (where the body is 'attacked' by its own immune system).
  • Diabetes or impaired glucose tolerance, as this medicine may increase the level of glucose in your blood.
  • Impaired kidney function or liver function.
  • Smoking - may reduce the effect of Melatonin medication as smoking can increase the breakdown of melatonin by the liver.

Children and adolescents - not suitable for under 18 years, safety and efficacy are unknown.

Other medicines

Tell your doctor or pharmacist if you are taking or will take melatonin whilst also taking any of the following:

  • Fluvoxamine (used for the treatment of depression and obsessive-compulsive disorder), as fluvoxamine may increase the effect of melatonin.
  • Psoralens (used for the treatment of skin disorders e.g. psoriasis), as psoralens may increase the effect of melatonin.
  • Cimetidine (used for the treatment of stomach problems such as ulcers), as cimetidine may increase the effect of melatonin.
  • Estrogens (used in contraceptives or hormone replacement preparations), as estrogens may increase the effect of melatonin.
  • Quinolones (used in the treatment of bacterial infections), as quinolones may increase the effect of melatonin.
  • Rifampicin (used in the treatment of bacterial infections), as rifampicin may decrease the effect of melatonin.
  • Carbamazepine (used in the treatment of epilepsy), as carbamazepine may decrease the effect of melatonin.
  • Benzodiazepines and non-benzodiazepine hypnotics (medicines used to induce sleep, e.g. midazolam, temazepam, and zaleplon, zolpidem, zopiclone), as melatonin may enhance the sedative effect of such drugs, and may enhance certain side effects of zolpidem (morning sleepiness, nausea, confusion).
  • Warfarin (anticoagulants), as melatonin may influence the effect of the anticoagulant warfarin.

Melatonin tablets with alcohol and food drink

Alcohol should NOT be taken whilst taking melatonin. Alcohol can impair sleep and potentially worsen certain symptoms of jet lag (e.g. concentration, headache, morning fatigue).

Pregnancy, breastfeeding, and fertility

Seek medical advice, if you are pregnant or breast-feeding or think you may be pregnant or are planning to have a baby. Melatonin crosses into breast milk. The effects on babies is unknown and therefore it is not recommended. Melatonin crosses the placenta and the risks to the unborn are unknown. Women who might become pregnant MUST take contraception if taking melatonin.

Operating machinery and driving

Melatonin can decrease alertness for several hours after intake - do NOT drive or operate machinery after taking.

How to take

Adults only - 1 tablet daily for a maximum of 5 days. If not working, 2 tablets daily. Take first tablet(s) on arrival at destination at your usual bed-time. On the following days take at your usual bed-time - should not be taken before 20:00 hr or after 04:00 hr. Take tablets whole with water or other liquid (not alcohol), not within 2 hours before or after food.

Courses of melatonin treatment can be repeated for each episode of jet lag up to a maximum of 16 treatment periods per year.

If you have taken more than recommended, please contact your doctor, hospital, or pharmacy. Common symptoms of overdose are drowsiness, headache, dizziness, and nausea.

If you forget to take a tablet at bedtime and wake during the night you may take the forgotten dose but at no later than 04:00 hr. Do not take a double dose to make up for a missed dose.
