Bangkok is a crowded, bustling city, and though pharmacies are plentiful, carrying a small first aid kit will save you time and trouble. Items such as Band-Aids, antiseptic wipes, pain relievers, and motion sickness tablets are easy to forget but can be a lifesaver during your holiday. This is especially valuable if you will be taking boat trips, long tuk-tuk trips, or going on tours out of the city. Having your medication ready in advance means that you will not have to rush to find a pharmacy in an unfamiliar area, which will give you a sense of security during your trip.
