No idea, ask in your health center.I imagine you will have to demonstrate at the NHI (National Health Insurance) that you live there with some rent or work contract to give you assistance.In Edinburgh there is Spanish consulate but the support is bad, at least for me that the Covid caught me there and they did not give me any assistance.
Now they are not "European Union" so I don't know if the European health card accepts it.
The other option is to send you a relative from here the material and insulin.
Years before knowing that he was diabetic, he was traveling with a friend who was DM1, and he was carrying a detailed medical report and his translation certified into English, he carried all the material he could for twice the time planned in his boxesOriginals not open, and if we were going to work longer, I went to the local health center or hospital A for the recipe, for the strangers it was much more expensive.In England I went to a clinic for the recipe and I think it was eight pound the lantus. I hope I have helped
