When I have to take antibiotics I will always get a yeast infection. Is thrush like a yeast infection? My family has been sick, so today I thought that it was time to take them in for antibiotics. I will probably have to get some too... so do you think that because I get yeast infections from antibiotics I might get thrush too? Can you prevent this? And is what they give you expensive? Is there a cheap/ sure fire way to get ride of thrush? thanks!
