Hello,

Thanks for writing to DoctorSpring.com with your health concern.

1. You take your pill at 1 pm on the day of travel, Seoul time. Then you board the flight at 1 am , 12 hours later. You reach Amsterdam after another 12 hours approximately.
So say you would reach Amsterdam at 1 pm itself, going by Seoul time ( 24 hours later more or less ).
So you take a pill as soon as you reach Amsterdam, whatever time it is over there locally.
And then continue taking the pill at that very time everyday for the rest of the month.
Say you reached at 9 pm Amsterdam time, so take a pill then, and then have the pill at that time everyday while you are out there.
Did this make sense, and is it clear ? I would not mind explaining again..

2. Given your age and weight, yes, DVT is a concern, but only with long term use. A couple of packs , one that you have used, and the current one, just two packs, will not at all carry a risk of DVT.
Particularly as you have had a safe history in the past with pills.
Yes, book an aisle seat, move around every hour or so ( take a walk down the aisle ).
Keep exercising your calves and take aspirin, starting 3 days before the trip, and stopping when you reach, again doing the same on the return journey.

All the best, Please feel free to discuss this further.
Wish you good health.

Hi again,
No, shifting it 2 hours later and then taking it at the same time everyday will not reduce the effectiveness at all.
Take care.
