Has anyone recently traveled to Brazil with medication and can share your experience? I’ll be staying there for a month and I am on a medication that needs to be kept cold so I will have it in my carryon in a small cooler case (like this https://a.co/d/09laVEDA) with the medication, syringes, and some alcohol swabs. I will have my prescription but it’s in English so not sure if that is useful. Do I need to declare it since it is only for my personal medical use? Flying into GRU if that makes any difference.
