I have traveled internationally after liver transplant. Been to Mexico and Europe several times. I had to wait a bit to get past monthly blood draw. Once tacrolimus hit stable and consistent trough. I had to be conscious of time change a meds. In Europe I kept same scedule and just took in middle of the night rather than wean into time difference. That would have taken me a week on each side to move 30 minutes daily to get to the 7 hour difference. Just easier to adjust my taking to there time. I do 8 am and pm at home, so I just took at 3 in afternoon and 3 am during evening. I did purchase med jet insurance. I know people who have it. Will fly in with med team and transport you to hospital of choice. I know someone who used it from Europe to Wisconsin when he got sick. It cost me $300 per year. For me worth it for peace of mind. Cost less than ambulance ride back home. It can be used nationally or internationally. Has couple different plans. One provides terrorist or natural disaster evacuation in addition to the medical . That a bit higher. I'm not sure of that cost. I do basic medical. Good luck. If not now, travel is possible.
