Pharmacy
There is a well-known and knowledgeable staff that advises customers and provides great care. For expats or travelers, simply describe your symptoms and let these professionals help you. You can find this pharmacy in four different locations in Ho Chi Minh City and it is a very trustworthy place.
The medicine they offer is of an international standard and the same you would find back home. If you are looking for a particular brand just ask the staff and they can tell if they have it for you. Even medicine you would normally need a prescription for is sometimes available over the counter in Vietnam, so do not hesitate to ask if you are in need of something specific.
