Basically you need to figure out what time it is in your home time zone and take it at that time. For example, if you live in Washington, DC, and you travel to Spain, which is 6 hours ahead, you should take your pill 6 hours later in the day than you normally would. So if you take your pill at 9AM in DC, you should take it at 3PM in Spain.
If you use our pill reminder system, you're good to go while traveling; we'll always send the reminder based on your home time zone. If you remember your pill by setting an alarm on your phone, however, make sure to adjust it as needed when you're on the road.
If it's easier (for example, if your usual pill time falls in the middle of the night wherever you're visiting), you can change your schedule, as long as you don't go more than 24 hours without a pill. So, if you live in DC and you go to Spain and want to stay on a 9AM schedule, it's totally fine to take your next pill at 9AM Spanish time (18 hours after your last East Coast pill).
Also, if you’re traveling long enough that you’ll be starting a new pack of pills while you’re gone, don’t forget to stick them in your suitcase!
