How do I adjust medication times when crossing time zones?

For medicines where exact timing is flexible, the common approach is to keep the interval between doses through the travel day, then shift by one to two hours a day until doses land at sensible destination times. Timing is critical for some medicines, so confirm your plan with a pharmacist.

Does this tool save my medication details?

No. Nothing you type is stored or sent anywhere. The schedule is worked out in your own browser and disappears when you close the page.

Should I take my pills on home time or destination time?

For short trips many people stay on home time, and for longer stays they shift gradually to destination time. Which is right depends on the specific medicine, so ask your pharmacist or prescriber.

What if I miss a dose while travelling?

Do not double up to catch up unless you were specifically told to. Follow the instructions in your medicine's leaflet and contact a pharmacist if you are unsure.

Can I keep my medicines in a pill organiser when I fly?

Organisers are convenient and widely used, but carrying medicines in labelled original packaging in your hand luggage avoids problems at some borders and in a medical emergency.

Destination time zone

Your dose schedule

Destination time is +5 hours from home. Your usual doses are at 8:00 am home time.

Travel day: keep the interval

Through the journey, the safest general approach for most medicines is to keep roughly 24 hours between doses and ignore the clock on the wall. Read both columns so you always know which clock you are using.

Dose times during travel in home time and destination time
Dose	Home clock	Destination clock
1 (Travel day)	8:00 am	1:00 pm
2 (Next day)	8:00 am	1:00 pm

After arrival: settling onto destination time

Where your pharmacist confirms the timing is flexible, moving up to 1 hour a day gets you onto destination times in 5 days without a large jump.

Dose times for the days after arrival, in destination time
Day at destination	Dose times (destination clock)
Day 1	12:00 pm
Day 2	11:00 am
