I always get a yeast infection from antibiotics.  I had a bad case of bronchitis and was on Augmentin for 10 days and ended up with one of the worst yeast infections I've every had.  My acupuncturist recommended this and it was (and is) AMAZING!  I ordered this in conjuction with Yin-care®'s Plastic Accordion Applicator and used it in the shower.  I got pretty much immediate relief. I will definitely be ordering this product again.
