Jet Lag Treatment
A private pharmacist-led service to help reduce the impact of jet lag on long-haul travel. After a consultation, you may be supplied with melatonin to help re-align your body clock.
What is jet lag?
Jet lag is a temporary sleep disorder that occurs when you travel quickly across multiple time zones, disrupting your body's internal 'clock' (circadian rhythm). It's especially common after long-haul flights and can affect both holiday enjoyment and work performance abroad.
- Daytime sleepiness and fatigue
- Difficulty falling asleep at night
- Poor concentration or memory
- Mood changes, irritability or low motivation
- Digestive upset — constipation, diarrhoea or nausea
- Bladder disturbances
Who this service is for
- Adults aged 18 and older
- Travelling across multiple time zones on long-haul flights
- Frequent flyers and business travellers
- Holidaymakers on long-haul trips
When it may not be suitable
- Under 18
- Pregnant or breastfeeding
- Severe liver or kidney problems
- Autoimmune disease or history of seizures / epilepsy
- Taking medicines that interact with melatonin (e.g. SSRIs, benzodiazepines, oestrogens, warfarin, quinolones, rifampicin, cimetidine, carbamazepine)
Treatment we can provide
Melatonin 2mg prolonged-release tablets
How it works: Melatonin is a naturally occurring hormone that regulates sleep-wake cycles. Supplementing it can help re-align your body clock after long flights.
How to use
- Take 1 x 2mg tablet 30–60 minutes before bedtime at your destination
- Swallow whole (do not crush)
- Maximum 5 days of use
- Up to 10 tablets supplied — enough to cover a return long-haul journey
Melatonin is licensed in the UK for insomnia in over-55s, but not specifically for jet lag. Its use here is considered 'off-label' but is supported by clinical guidance and evidence of benefit. Avoid alcohol during treatment — it reduces melatonin's effectiveness.
Possible side effects
Generally mild and uncommon with short-term use. May include drowsiness, headache, dizziness, vivid dreams, digestive upset or mood changes. Seek medical advice if you experience persistent or severe side effects.
Important
When to seek medical help
Seek medical advice if side effects are persistent or severe, or if sleep problems continue well after you return home.
