hi Sally,
Paula posted a very long thread about travelling abroad with Enbrel,
i really don't know how to find it now.
i travel in this Country with Humira, and i bought a small sandwich size coolbox and packed my Humira in bubble wrap and placed a frozen pack each side of it,
i got a Thermometer from Healthcare at Home, and you can phone and ask to speak to Pharmacy about travelling.
Paula and her Hubby did experiments as to the best way of packing it all,
try and do a search maybe under the drug section.
