that should clear a lot of this up.
She is perfectly right antibiotics won't do anything for a yeast infection and if anything will just make it worse because they will kill all bacteria even the good that helps to keep the vagina clean there for allowing the fungal yeast infection to grow.
Chances are if you are female and have ever had any kind of antibiotics for anything you will find it has brought on a yeast infection.
Don't be so fast to judge replies as there are far to many people on here that give the wrong advice!
You are totally wrong fluconazole is not an antibiotic its an antifungal medication. Yeast is a form of fungus not a bacteria, yes all vaginas do contain yeast but they also contain bacteria that keep the yeast to a certain level, when you take antibiotics they kill all bacteria in the body wether it be good or bad that then allows the yeast in the vagina to grow to higher levels causing thrush. If you get BV then you will be prescribed some form of antibiotics because that's a bacterial infection and often followed by a yeast infection after you finnish the course of antibiotics.
Please don't be so defensive towards replies if you don't really understand the difference between bacteria infection and a fungal infection.
