Bactrim would be a better.This combination drug has broad-spectrum activity. It is effective against Gram-positive bacteria such as streptococci and some strains of staphylococcus.If you cant get Bactrim I would use Amoxicillin since it is bactericidal and is shown to be active against most strains of Gram-positive aerobes such as: Enterococcus faecalis, beta-lactamase-negative strains of the Staphylococcus spp., Streptococcus pneumoniae, and the alpha-hemolytic and beta-hemolytic strains of streptococcus.
