How do I transfer my diabetes medication prescription to Thailand, and what are the costs involved?

Transferring your diabetes medication to Thailand can be straightforward. You can buy diabetic medications over the counter in Thai pharmacies without a prescription. Prices vary, but some users report costs of around £22 for a three-month supply of insulin and other necessary medications when registered with a local hospital. It's common for expats to bring a supply from the UK, often enough for six months, in their hand luggage. Note that you only need prescriptions for controlled substances like opiates. Shopping around or ordering online may provide additional savings.
