Hi,
I am in Thailand now and needed to restock my Novorapid and Levemir supplies in both Bangkok and Chiang Mai. I did a lot of asking around to find reputable pharmacies due to the significant number of counterfeit drugs here. I have not had any issues with the insulin quality from where I purchased mine from. I have always timed my flights to be back in Thailand after 30 days whilst travelling SEA to get insulin. I personally didn't want to risk using insulin from Laos/Cambodia/Vietnam as Bangkok has a much better health care system.
Insulin is not cheap here and either are test strips. It is available over the counter unless you go to a hospital pharmacy, which will require a script.
Levemir flexpen=650 Baht (800-1200 at a hospital + a fee for doctors prescription )
Novorapid penfill =350 Baht
Test strips = 400-500 Baht for a box of 25
PM me if you would like the pharmacy locations. In Bangkok the Bumragrund hospital stocks both insulins however you will be required to see a doctor first for a prescription. A few months ago I spoke to the in house pharmacist. The hospitals in house pharmacy is considerably more expensive.
TIPS
-Thai food tends to run my blood sugars high. After doing a cooking course I believe its due to the significant amount of sugar that's put into the sauces...it will be trial and error at first...
-Get a Frio wallet even for your insulin supply you carry in your purse. Outside temperatures are above 25 degrees most of the time
-There is always a risk of your bag being snatched ( I have met a few people that had this happen in SEA). Split your insulin supply up and take two metres with you. Since I am travelling alone I keep some insulin/one metre in my hotel room and the rest in my backpack...depending on where you stay never leave it all in your room...it could get stolen.
-Carry lots of hypo food with you. I use sugar packets. I found my basal requirements have lowered due to being more active and also the hot weather.
-Have a gluco pen with you just in case.
I have been backpacking solo for 5 months without a fridge therefore had to make multiple purchases (Including in Zimbabwe) so I know how stressful it can be thinking about your diabetes. Let me know if you have any questions/need any tips.
I hope you have a great trip!
