Hi Claire, there is also our web page
https://www.pituitary.org.uk/information/related-links/travel-insurance/ These are companies other patients have used. Consider too if your bank account has benefit of travel insurance ('free'), but best to call them for any added premium for your hypopit.
We have a travel letter your endo nurse/GP can complete to assist when going through customs with meds, plus helps if you were to need medical help at your holiday destination. I can email you this if you want it
