Hi
I take Novorapid and Lantus. Travelled for six months from last October through India, Nepal and South East Asia finishing in Sri Lanka (in time for the second test in Colombo). I took sufficient insulin with me and had no problems. Used a couple of Frio bags when on flights and buses etc and used fridges at hotels/guesthouses/hostels as far as possible. At the start the Frio bags only held my Lantus so Novorapid was uncooled for some journeys. My HBA when tested on my return was fine.
Am going to China for 9 months from early October and have literally just got off the phone from Novo Nordisk. They told me Novorapid is available there and in Malaysia. If you want to talk to them their non 0845 number is 01293 613555.
It might be worth keeping testing strips in the fridge as you go along as when I got to my last pack they kept giving error readings, can only assume they did get heat affected.
Good luck, enjoy it and I'm sure you will have a great time.
