Is melatonin effective sleep aid medicine?

In the UK, licensed forms of melatonin are prescribed either for the management of insomnia in adults over 55 years of age or to help with jet lag.

Cochrane Collaboration (a world-wide collaboration of scientists) looked at the effectiveness of melatonin in the management o jet lags. Cochrane looked at a number of trials that involved airline passengers, airline staff and military personnel who used melatonin or placebo ( a dummy pill) to evaluate the effectiveness of melatonin.

Cochrane concluded that melatonin is ‘remarkably effective’ in preventing or reducing jet-lag. It also concluded that short-term use of melatonin is safe (Herxheimer & Petrie, 2002).

In the UK, melatonin is classified as a prescription-only medication. The supply of prescription-only medicines is possible after a prescription (NHS or private prescription) is issued to the patient by a doctor or another qualified prescriber.

How to get melatonin in the UK?

1. Getting melatonin prescribed by NHS doctor

The most appropriate way of getting melatonin in the UK is by having it prescribed. Individuals who experience a jet-lag or seek temporary aid to their sleeping problems may contact their GP and discuss the possible use of melatonin.

Alternatively, over the counter sleeping medicines such as sedative antihistamines can be used as a temporary aid to sleeping problems. See the next section.

2. Buying melatonin from UK online pharmacies (private service)

A number of online pharmacies (for example, UKMedsTheOnlineClinic) offer private services by which patients are able to buy prescription-only medicines after online consultation takes place (usually screening questionnaire).

Online consultation covers general health questions, including questions about any concomitant conditions. The screening questionnaire is then reviewed by a doctor who issues a private prescription with drugs being delivered to the patients home. Consultation fees are usually included in the total price of prescribed medicines.

3. Getting melatonin on a private prescription 

It would be possible to get melatonin on a private prescription from a doctor after a private consultation takes places (Online GP services or Private consultation). A number of online GP services provide private consultation services. Alternatively, similar services may be offered for individuals who have private insurance in place.

The difference between this and the previously discussed route is that a private prescription is issued, which patients need to take to a pharmacy to get a supply of melatonin. When a drug is supplied on a private prescription, a patient needs to cover the cost of medication and any additional supply fees, regardless of their age or NHS exemption.

4. Buying melatonin from abroad

In many countries, including the USA, melatonin is classified as a supplement and is available over the counter. Non-UK websites such as Amazon.com and eBay lists melatonin on those websites. See the next paragraph for more details.

Can you import melatonin for personal use?

It is possible to buy melatonin from abroad, for example, from the USA (Amazon.com, eBay.com) and import it for personal use. It is illegal to sell or redistribute imported melatonin in the UK since melatonin is classified as prescription-only medicine in the UK.

Please note the higher delivery cost to the UK. You may also have to pay import duty tax, which may contribute to the high overall cost.

The mainstream management of temporary sleep disorders in the UK involves the use of sedative antihistamines, most of which are available without prescription from the pharmacy. Common antihistamines use in sleeping pills include:

  • Diphenhydramine (for example, Nytol)
  • Promethazine (for example, Sominex)
