Hello, I'm leaving today for 7 weeks in France. I also spent a month there in the summer. I traveled with my Tymlos. There is no reason to miss a day of medication. I purchased a travel cooler like a thermos that keeps the medicine cold for up to 30 hours. I also brought the box with the prescription on it. I was asked to see the prescription in London, but otherwise no worries getting through security. The one thing that makes traveling difficult is during a hot summer. The medicine should not get over 78 degrees. The thermos has an inner piece that needs to be frozen. If staying in a airbnb it's easy, not so much a hotel. I have a home in France so I just keep it in the fridge all the time. The same at home. I'm going over to Spain mid October for 2 weeks and I will just carry it as temperatures will be perfect by then. I'm having great results and don't want to miss a day of bone growth!
