Many drugs are available over the counter here, without a doctor's prescription. Three of the most common chain pharmacies in Thailand that come to mind are Watsons, Boots and Fascino. If I were you, I'd do a little research on the web and see if you can buy your meds while you are here. There's even a chance that they may cost you less money, especially if you are from the US.

I bought a mobile phone off Lazada from China a couple of years ago. No additional VAT charges. Just the price of the phone and shipping.

right! Same as HIV, Hepatitis, Cancer and countless other diseases! 😂

I haven't completed the journey you are inquiring about but maybe this will help you.
