Depends what kinda fungus prob he's having?
In general, ppl would go for miconazole (daktarin decozol...goes by many generic names).
ketoconazole (nizoral) is much more expensive compared to the regular antifungal.
if u wan something new school, lamisil (brand) is fantastic and expensive.

yet again rm30/week is ridiculous. never heard of it unless the infected site is large and u practically had to use the whole tube.....
