Adjusting medication times to time zones when traveling

When you travel to a different time zone, your phone's clock changes on its own. But what happens to your medication reminders? Does the reminder that rings at 9 a.m. at home arrive on the new city's time, or on your home time? Knowing the answer before you set off, not on the road, makes the trip go much more smoothly.

Ask your doctor or pharmacist first

How to arrange your medication times on a trip across time zones is a decision specific to your medication and your situation. An app doesn't make this decision, and you shouldn't make it by guessing either. Ask your doctor or pharmacist how your dose should be shifted.

A few days before you set off, you can prepare questions like these:

• The time difference between here and where I'm going is this many hours; how should I arrange my medication times?
• How should I plan doses on travel day itself?
• How should I switch back to my usual schedule when I return?

Save the answers you get as a note. Then you have somewhere ready to check if you're unsure on the road. Similar questions come up when the clocks change for daylight saving time; we cover them in daylight saving time and your medication schedule.

What time do reminders go by?

Reminder apps can handle time zones differently. Some always ring the reminder according to the local time wherever you are: a reminder that rings at 09:00 at home will also ring at 09:00 local time where you've traveled. Others stay tied to a fixed time zone and keep ringing according to your home time; in that case the reminder may arrive at a completely different hour where you are.

Which one is right depends on the schedule you've agreed on with your doctor. What matters is knowing, before you set off, where this setting stands in the app you use.

On a short trip, say a couple of hours' time difference for a few days, not changing the setting at all can also be an option; on a longer trip the situation may be different. Make this distinction together with your doctor or pharmacist too, and choose the app's setting based on that decision.

Settings to check before you set off

1. Your phone's date and time settingYour iPhone's time zone is usually set automatically. Know whether this is on, so the time changing after you land doesn't catch you off guard.
2. The app's time zone preferenceDoes the app use your phone's clock, or is a fixed time zone selected? Set it according to the schedule you've agreed with your doctor.
3. The times in your plansReview what times each medication plan will give reminders at. If your doctor told you to change the times, make the change before you leave.
4. Reminders for the first few daysPicture in your mind which reminder will arrive when during the first days of the trip; note any that fall during sleep or a flight, and ask about those too.
5. How notifications appearCheck that notifications are turned on and how they look in silent mode. Sending a test notification is the easiest way.

On the road: don't forget to log

Your routine gets disrupted while traveling, and the time you take your medication can shift too. That's why logging it right away when you take it or skip it becomes even more important than at home. Recording the actual time comes in useful when you're explaining to your doctor afterward what happened when.

A practical reminder too: make sure you're carrying enough medication for the whole trip. Check the airline's and your destination's rules in advance for how to carry medications.

If you also log your period days while traveling, tracking your period while traveling can help you keep the dates right.

Time zone settings in Oveluni

In Oveluni, time zone settings live in two places:

• Settings → Date and time: You can use your iPhone's settings, or choose the time zone yourself.
• Medication plan: When you set up a new medication plan, the plan's time zone sits alongside the times, amount, and start and end date. Doctor visits also record a time zone.

Before you set off, you can check how notifications look with "Send test notification" in Reminder settings. On the road, when you take or skip a dose you add the actual time and a short note to the intake log; this doesn't change your plan.

If you keep a period record, there's one more detail: period days keep their calendar date while traveling. The day you record doesn't shift to another day on the calendar because of the time difference.

Oveluni gives reminders according to the plan you set up. How to arrange the times is a decision you and your doctor make together.
