No anti malarial medication is needed in South America unless you are REALLY going off the beaten track.
I've strong view about the high cost, side effects and efficacy of such medication and would not consider it unless going somewhere where malaria is rife and without it you would be sure to catch it.
A preferable alternative (IMO) is to carry a course of quinine sulphate which is very cheap and can be used to treat suspected cases of malaria.
Mossie repellent should see you right in South America. Happy travels.
