I would agree and say go for the oral tablet as it is definitely the most effective way of getting rid of it. There is a supplement called acidophilus which is a good preventative measure if you find you start getting repeated attacks. Thrush is a fungal yeast infection called Candida Albicans which can live in our guts. It flares up in our guts, mouths and vaginas for a variety of reasons such a stress, a diet high in yeast and oral antibiotics which can deplete the good 'flora' in our guts.
