is absolutely correct. My wife is diabetic and we moved here to Thailand 4 years ago. We brought 5 months supply of her medication. I did a lot of checking the best option for her to carry on managing her condition.
I checked at pharmacies in Cha Am (where we live), Hua Hin, Bangkok and Pattaya. When it came to price the results were, most expensive first:
1. Private hospitals, by a long way the most expensive option. There was quite a variation between hospitals, even different hospitals in the same chain.
2. Private clinics.
3. Pharmacies, again quite a variation between pharmacies. Pattaya was the cheapest although our local pharmacy in Cha Am offered to do a price match if we bought 3 months supply at a time.
4. Government Hospitals, because of where we live we ended up using Hua Hin Hospital. Cost of medication is 25% less than buying at the cheapest of the pharmacies.
