Hi Veronica
I have travelled Europe with Enbrel but never really been well enough (or perhaps that should read confident enough!) to go further!
Always worth doing a test run before you go to ensure your cool packs keep the injections at the right temperature. I'm not sure about the warming up process? I was told that once Enbrel is out of its 'chill factor' it must be used within a few hours and not re-chilled as will affect the efficacy. You would need to check this. I use a small collapsible lunch bag (the kind you get for school lunches) and two ice packs. The info given by Healthcare at Home (who I have found to be brilliant incidentally) is actually incorrect!
Injections MUST be carried in hand luggage (too cold in the hold!) and you must check with the airline that it is permissible for them to be carried before you travel. I was not allowed to take my injections on board a Jet2 flight and had to leave them at the airport!
You will also be obligated to ensure the safe disposal of used needles at your destination.
I think perhaps in view of your travel proposals it might be worth speaking to rheumatology for their advice. The meds you are on, due presumably to your moderate to severe disease status, and the plans you have don't quite seem to go hand in hand!
As regards to Humira, please don't give up yet it is still very early days! It can take a minimum of three months to fully load the system before you will see a noticeable difference ( although sometimes sooner!). You should, of course, only come off the medication with the agreement of your consultant as a suitable alternative would need to be put in place.
I know this doesn't sound optimistic for your plans but better to proceed with some caution whilst plans can still be adapted! Good luck
