text: what can u do if u have yeast infection?   if you mean a vaginal yeast infection, it's probably the result of taking an antibiotic.  get monostat 3 or 7-day at the drug store.  it will have a tube of itch cream that you might want to keep in your purse.  yogurt does have microorganisms in it, but not nearly enought.  you also can buy acidopholus in the vitamin section.  try to find a brand that doesn't say to refrigerate after opening.  my doc has okayed me to take 3 times the dose on the label each day.  normally i take one every other day.
