Jet lag treatment UK: tablets, sleep tips and east-west travel
How to treat jet lag when flying from the UK — sleep-timing tablet use, light exposure, sleep hygiene and assessed options for long-haul travel.

Long-haul travel disrupts your body clock faster than it adapts. The good news: jet lag is self-limiting and responds to timed light, sleep and — when appropriate — pharmacy tablets.
East vs west from the UK
| Direction | Example routes | Difficulty |
|---|---|---|
| East | UK → Dubai, India, Thailand, Australia | Harder — you need to fall asleep earlier |
| West | UK → New York, Caribbean, South America | Easier for most — you stay up later |
Plan recovery time into your itinerary — especially for important meetings or sport.
Non-drug strategies (first line)
- Set watch to destination time when you board
- Sleep on the plane if it is night at destination; stay awake if it is day there
- Get outdoor light at destination morning — strongest clock reset signal
- Avoid long daytime naps — limit to 20 minutes before 3pm local time
- Hydrate; go easy on alcohol and caffeine after arrival
- Eat on local meal times — helps circadian rhythm
Jet lag tablets in the UK
Prescription sleep-timing support is licensed for short-term jet lag in adults over 18 in the UK — supplied after a prescriber suitability check, not as a daily sleep pill for chronic insomnia.
Typical use:
- Take at local bedtime for up to 5 nights after arrival
- Do not combine with sedating alcohol or other sleep medicines without advice
- Not suitable for pregnancy, breastfeeding, autoimmune conditions or some medicines — assessment filters these out

Before you fly — travel health checklist
Jet lag is only one part of travel medicine. Also plan:
- Anti-malaria tablets if your destination requires them — start before travel
- Travel sickness tablets for long transfers

When jet lag might be something else
See a clinician if:
- Sleep problems persist weeks after return with no travel planned
- Snoring with daytime sleepiness — possible sleep apnoea, not jet lag
- Low mood or anxiety dominating after travel — may need separate support

The travel health programme covers jet lag support, malaria prevention and motion sickness — comparing services where a prescriber or pharmacist reviews your trip dates.
Frequently asked questions
What is the best treatment for jet lag from the UK?
Combine timed light exposure, sleep at the destination local night, short naps only if needed, hydration and — where suitable — prescription sleep-timing tablets taken at destination bedtime for the first few nights. Eastward travel is usually harder than westward.
Can I get jet lag tablets in the UK?
Prescription sleep-timing tablets are licensed for short-term jet lag in adults and supplied after a prescriber suitability check. They are not a general sleep aid for everyday insomnia.
When should I take jet lag tablets?
Take at local bedtime at your destination for up to 5 nights after arrival — not before travel unless your prescriber or pharmacist advises a specific schedule. Timing matters more than dose.
How long does jet lag last?
Roughly one day of adjustment per time zone crossed — often longer after eastward flights. Most people feel substantially better within 3–5 days.
Are jet lag tablets safe with other medicines?
Sleep-timing tablets interact with some medicines including blood thinners and immunosuppressants. Complete a clinical assessment and declare all medicines before use.
