Keeping a medication schedule while travelling
A morning tablet that slowly migrates into the afternoon is almost always a scheduling bug rather than a memory problem.
Travel breaks medication routines in a way that looks like forgetfulness and usually is not. The anchors that normally hold the routine in place, breakfast at a familiar table, the kettle, the evening news, are all missing at once, and the software is often quietly working against you as well.
The bug hiding in "every 24 hours"
There are two ways to express a daily dose, and they are not equivalent.
Wall clock time means eight in the morning, wherever the person happens to be, whatever the clocks have done.
Fixed interval means twenty four hours after the last one.
These behave identically until something disturbs them. Then the interval version drifts. Take a dose two hours late once and every subsequent dose shifts by two hours, so the morning tablet gradually becomes an afternoon tablet without anyone deciding anything.
Daylight saving does the same thing on a fixed schedule twice a year. Fly across a few time zones and the interval version keeps you on the routine of a country you have left.
For most routine medication, wall clock time is what people actually want, and it is what CareDuo schedules: the dose belongs to the person's day, in their time zone.
Some medication genuinely does need fixed spacing. That is a clinical question, and a pharmacist will answer it properly in a way that no app setting can.
Before you travel
Ask the pharmacist about the flight, not the app. Whether to shift a dose gradually, take one early, or simply keep to home time is a medical question and it depends on the medication. It takes one phone call, and the answer is usually straightforward.
Take more than you need, in hand luggage. Hold baggage goes missing. The supply calculation people make is nearly always the exact number of days, which leaves no margin for a delay.
Count in doses, not in tablets. How many more times can this be taken is the number that matters. A dose of two tablets is one dose. Counting objects gives an answer you then have to convert under pressure.
Check the schedule survives the change. Once the phone updates to local time, look at whether tomorrow's reminders sit where you would expect them.
While you are away
New anchors have to be chosen deliberately, because the old ones are not there. Whatever is reliable in the new setting works: the hotel breakfast, coming back to the room in the evening, plugging in the phone at night.
Expect the first two days to be the worst. Routines that were automatic at home have become decisions, and decisions are what get missed.
What the person at home sees
If somebody is following the routine from home, travel changes what their day looks like too.
In CareDuo the day belongs to the person taking the medication, in their time zone. So a family member in London following a parent in California will see the day unfold on California time, and a missed dose alert may arrive at an odd hour.
That is the correct behaviour, and it is worth mentioning to each other before the trip rather than discovering at four in the morning. The alternative, translating everything into the caregiver's time zone, produces a day that makes no sense to the person actually living it.
Coming back
The return trip is the one people underestimate. The routine has been rebuilt around temporary anchors, and those anchors vanish on arrival home while tiredness makes everything harder.
The fix is small: put the medication back where the old habit lives, beside the kettle or wherever it was, on the first evening rather than the third day.
The short version
- Wall clock schedules survive travel and daylight saving. Interval schedules drift.
- Ask a pharmacist about timing changes, not an app.
- Pack extra doses in hand luggage, counted as doses.
- Choose new anchors deliberately on arrival, and restore the old ones on return.
- Agree in advance that alerts at home will arrive on the traveller's clock.

Common questions
Should reminders follow local time or home time?
For most routine medication, local time is what people want: a breakfast tablet should arrive at breakfast wherever you are. Some medication needs fixed intervals instead, and that is a question for a pharmacist rather than for an app's settings.
What happens to my reminders when the clocks change?
In a well built app, nothing. A dose set for eight in the morning arrives at eight in the morning before and after the change. Apps that count in fixed intervals instead will shift by an hour twice a year.
Will a family member at home see the right times?
In CareDuo the day belongs to the person taking the medication, in their time zone. A caregiver may therefore get an alert at an unusual hour while the traveller is away, which is geography working correctly rather than a fault.
