If you take any regular medication bring double your needs in case of loss or theft. In Thailand you can buy many medications over the counter without a doctor’s prescription, but it can be difficult to find the exact medication you are taking.
Contact your home country’s Department of Foreign Affairs or the equivalent and register your trip; this is a helpful precaution in the event of a natural disaster.
