What is Melatonin?

Melatonin is a hormone which may be used to treat jet lag in travellers crossing several time zones. Melatonin occurs naturally in the human body and is involved in regulating our sleep-wake cycle.

How does Melatonin work?

Normally, levels of melatonin increase when it gets dark outside, making you feel sleepy and tired to prepare your body for rest. When you travel to a place with a different time zone, your body clock takes some time to adjust to the change in time. Taking Melatonin can help you to sleep when it is nighttime at your destination and overcome the time zone gap.

How do I use Melatonin?

One tablet of Melatonin 3mg should be taken at your usual bedtime when you arrive at your destination, for no longer than 5 days. For frequent fliers, treatment may be taken for a maximum of 16 treatment periods per year.

How long does it take for Melatonin tablets to work?

Once taken, Melatonin tablets start working quickly to help you get to sleep more easily and overcome the time zone gap. Melatonin helps to speed up the process of your internal body clock adjusting to the new time zone while also minimising symptoms of jet lag.

Where can I buy Melatonin in the UK?

You can buy Melatonin 3mg from Pharmica by completing a short consultation. Melatonin tablets cannot be purchased over the counter and require a prescription. Following completion of your online medical consultation, you can get same-day or next-day delivery to ensure your treatment arrives promptly ahead of travel.

Side Effects

By its nature, taking this treatment can cause drowsiness so when using this medication no activities should be performed which would be dangerous to undertake when drowsy.

Some possible side effects include headache, drowsiness, chest pain, abdominal pain, dizziness, irritated skin, and increased weight.

 Information Leaflet

Always read the patient information leaflet before commencing treatment.

Important: We advise you to always read the patient information leaflet inside the medication box, as the generic medication may not always entirely match the patient information leaflet listed. Please contact us if you have any questions.

"I was quite skeptical at first that…"

Product Review:

Really helps with jet lag with no “hangover’ grogginess the next day.

Service Review:

I was quite skeptical at first that they were genuine but after reading a few reviews I took a chance and ordered and was pleasantly surprised that the medication was received promptly and is the genuine product. As a result, I have been using them regularly for quite a few months now and have not been let down once. The ordering process and consultation form is simple and easy to use, the prices are great and delivery is always within a couple of days. All in all a great experience and I will be continuing to use them for all my future medication orders.

"Pharmica’s Philosophy!"

Product Review:

Pharmica are a great company to have in your back pocket. They have knowledge and have an interest in their clients. They are bound as much as a chemist pharmacy to ensuring their clients have the healthiest interaction, and that the medication asked for is in their best interest. Give them a try!

Service Review:

Pharmica will always ask for extra information if needed before dispensing, which I feel is the safest way of administering medications online.
They will inform you at all stages of the process of buying from them. If they cannot fulfil an order they will let you know why.
