In the pharmacy in Bali, they can give medicine for almost any problem.
Do we bring medicine from home or are they good here?
It is not worth leaving home if you just do not have a specific allergy for which a specific type of medicine is a solution. In pharmacies in Bali, they can give medicine for almost any problem, in fact, they usually ask what medicine you take for similar complaints in Europe and try to give such content. In Bali, you can also buy antibiotics without a prescription, in exchange for some surcharge. So, if you get sick and want to quickly get over it, then a course of antibiotics will help you not to spend your vacation in bed.
