What is superimposed vaginal yeast? and how do you cure it?

Second infection...: Likely, you are referring to a seocndary infection that occurs after treatment has been initated for an infection such as a urinarybtract infection. The treatment usually involves antibiotics that disrupt the normal balance of bacteria in your vagina, causing a change in the ph of the environment that allows yeast to grow. A dose of Fluconazole should do the trick (drug is by prescription only).
