Travelling across multiple time zones can disrupt your body’s natural sleep pattern, leading to tiredness, difficulty sleeping, reduced concentration, and daytime fatigue. At Healthcare Pharmacy, we offer travel health advice to help you prepare for long-haul travel and manage the effects of jet lag.
Our experienced healthcare team can provide practical guidance tailored to your journey and destination.

Jet lag occurs when your body’s internal clock becomes out of sync with the local time at your destination. It’s most common when travelling across several time zones and can affect sleep, energy levels, concentration, and general wellbeing.
Common symptoms may include difficulty sleeping, daytime tiredness, irritability, digestive disturbances, and reduced alertness while travelling.
Our healthcare team can provide advice on managing jet lag before, during, and after your journey. This may include guidance on sleep routines, hydration, meal timing, light exposure, and other practical measures that may help your body adjust to a new time zone.
We can also discuss any wider travel health concerns you may have, as part of our Travel Clinic service.
We welcome patients from Hornchurch and the surrounding area looking for advice ahead of upcoming travel.
Melatonin is a hormone your body produces naturally that helps regulate your sleep-wake cycle. Melatonin is a prescription-only medicine in the UK and is not available for us to sell over the counter. If you’re considering melatonin to help with jet lag, this can be discussed as part of a consultation with an appropriately qualified prescriber, who will assess whether it may be suitable for you.
Timing is an important factor when melatonin is used for jet lag, as taking it at the wrong time could potentially shift your body clock further out of sync. Where treatment is considered appropriate, our team can explain how and when it would usually be taken, tailored to whether you’re travelling east or west.
Medication is only one part of managing jet lag. Our pharmacists can talk you through practical steps you can take during your flight and at your destination, such as light exposure, adjusting your eating schedule, and staying well hydrated, to help support a more comfortable journey.
Jet lag symptoms usually improve within a few days as your body adjusts. If you have a pre-existing sleep disorder, are taking other medicines, or have ongoing symptoms that concern you, please speak with our team or your GP. Melatonin can cause drowsiness; if prescribed, you should be advised not to drive or operate machinery until you know how it affects you.
