OK, I have posted before regarding taking prescription injectable drugs through multiple countries security and customs - thanks again for the informative responses.

I must keep the drugs below 4C so will need an ice brick.

What I need to know is how the ice brick will be dealt with. I have some long layovers in J lounges where the ice brick will melt to become a fluid brick of more than 100ml. I have a 9 hr wait in the TG lounge at BKK between flights from VTE - BKK - FRA - ATH. This little brick will be well and truly melted by ATH, any suggestions on refreezing it are also welcome!!
